General information
1. Honda's HISS (Honda Ignition Security System) immobiliser is fitted to XL650V models as an anti-theft device. The system will only allow the machine to be started if the correct registered key is used to turn the ignition ON. The system consists of a transponder which is part of the ignition key, a receiver which is fitted around the ignition switch, and the ignition control unit (ICU).
2. When the Ignition is switched ON, the ICU sends power through the receiver to the transponder. The transponder sends a coded signal back through the receiver to the ICU. If the signal sent by the transponder matches the signal stored in the ICU memory, the immobiliser indicator light in the tachometer (marked by a key symbol) comes on for two seconds, then goes out, and the ICU allows the engine to be started. If the key code signal is not recognised, or if there is a fault in the system, the indicator light stays on. If the light stays on, refer to the fault diagnosis and troubleshooting Sections below. Likewise if the light does not come on at all.
3. The ICU can store the codes for up to four registered keys. They keys should be kept separately (i.e. not on the same key-ring) as the proximity of another key to the one being used in the switch can lead to the signal from it being jammed, and the bike will not start. The key has a built in transponder which can be damaged if the key is dropped or knocked, gets too hot, is too close to a magnetic object, or is submerged in water for too long. If all the keys are lost, the ICU must be replaced with a new one, so always make sure you have at least one spare key. If a new key is obtained, it must be registered into the system before the bike can be started.
Key registration procedure to register a new key
Note: To do this you will need the Honda special tools (Part Nos. 07XMZ-MBW0100, 07YMZ-MCB0100 or 07XMZ-MBW0101, and 07YMZ-0010100) which are a wiring loom and adapter that plug into the ignition pulse generator wiring connector. If this tool is not available, registration must be carried at a Honda dealer with the special tool.
4. Obtain a new key from a Honda dealer, then have it cut to match the original key.
5. Remove the fuel tank (see Chapter 4), then disconnect the 2-pin ignition pulse generator wiring connector. Connect the special tool wiring connector to the ICU side of the connector, then connect the red coloured clip of the tool to the battery positive (+ve) terminal and the green coloured clip to the battery negative (-ve) terminal.
6. Turn the ignition switch ON using your original key. The immobiliser indicator light should come on and stay on (if It starts to flash after ten seconds, then there is a fault in the system, which will have gone into fault diagnosis mode, and the pattern of the flashes it emits should be matched with the fault code (see below)). Now disconnect the red clip from the battery positive terminal and leave it disconnected for at least two seconds, then reconnect it. The indicator should now come on for two seconds, then begin to flash repeatedly four times. This Indicates that the system is in registration mode. At this point the registrations of all keys except the one in the switch will have been cancelled, so if you have another spare apart from the new one you want to register, this will also have to registered.
7. Turn the ignition OFF and remove the original key, placing it well away from the receiver.
8. Insert the new key into the switch and turn it ON. The indicator should now come on for two seconds, then begin to flash repeatedly four times. This indicates that the system has registered the new key. Turn the ignition OFF and remove the key.
9. To register any other spare keys that will have been cancelled, repeat Steps 7 and 8. Up to four keys can be registered
10. On completion turn the ignition OFF. then remove the special tool and reconnect the ignition pulse generator wiring connector. Now turn the ignition ON using any of the registered keys to return the system to normal mode.
11. Check that all registered keys can start the motorcycle.
To register new keys with a new ignition switch
Note: To do this you will need the Honda special tool (Part No. 07XMZ-MBW0100) which is a wiring loom adapter that plugs into the ignition pulse generator wiring connector. If this tool is not available, registration must be carried at a Honda dealer with the special tool.
12. Obtain a new switch and two (or more if you want) new keys (which presume come with the switch).
13. Remove the faulty switch (see Chapter 9), but retain the receiver to fit with the new switch.
14. Remove the fuel tank (see Chapter 4), then disconnect the 2-pin ignition pulse generator wiring connector. Connect the special tool wiring connector to the ICU side of the connector, then connect the red coloured clip of the tool to the battery positive (+) terminal and the green coloured clip to the battery negative (-) terminal.
15. Place one of the original registered keys for the faulty switch next to the receiver.
16. Connect the new ignition switch to its connector in the wiring loom, but keep it away from the receiver. Turn the new switch ON with one of the new keys. The immobiliser Indicator light should come on and stay on. which means the ICU recognises the old key that is next to the receiver (if it starts to flash after ten seconds, then there Is a fault in the system, which will have gone into fault diagnosis mode, and the pattern of the flashes ii emits should be matched with the fault code (see below). Now disconnect the red clip from the battery positive terminal and leave it disconnected for at least two seconds, then reconnect it. The indicator should now come on for two seconds, then begin to flash repeatedly four times. This indicates that the system is in registration mode. At this point the registrations of all keys except the one near the receiver will have been cancelled.
17. Turn the ignition OFF and remove the new key.
18. Install the new ignition switch, then fit the receiver onto it (see Chapter 9).
19. Insert the new key into the switch and turn it ON. The indicator should now come on for two seconds, then begin to flash repeatedly four times. This indicates that the system has registered the new key. Turn the ignition OFF and disconnect the red clip of the special tool from the battery positive terminal.
20. Turn the ignition ON using the newly registered key. The indicator light should come on for two seconds, then go off.
21. Turn the ignition OFF and reconnect the red clip to the battery positive terminal.
22. Turn the ignition ON using the newly registered key. The indicator light should come on and stay on. Now disconnect the red clip from the battery positive terminal and leave it disconnected for at least two seconds, then reconnect it. The indicator should now come on for two seconds, then begin to flash repeatedly four times. This indicates that the system is in registration mode. At this point the registrations ot all old keys (for the faulty switch) are cancelled.
23. Turn the ignition OFF and remove the key, placing it well away from the receiver.
24. Insert the second new unregistered key and turn the ignition ON. The indicator should now come on for about two seconds, then begin to flash repeatedly four times This indicates that the system has registered the second new key. Turn the ignition OFF and remove the key.
25. To register any other new spare keys, repeat Steps 23 and 24. Up to four keys can be registered.
26. On completion turn the ignition OFF, then remove the special tool and reconnect the ignition pulse generator wiring connector. Now turn the ignition ON using any of the registered keys to return the system to normal mode.
27. Check that all newly registered keys can start the motorcycle.
To register new keys with a new ICU
28. Obtain a new ICU along with two (or more if you want) new keys. Install the ICU (see Section 5). Have the keys cut to match the original key for your ignition switch.
29. Insert a new key into the switch and turn it ON. The indicator should now come on for two seconds, then begin to flash repeatedly four times. This indicates that the system has registered the new key. If the indicator stays on foi ten seconds then starts to flash, then there is a fault in the system, which will have gone into fault diagnosis, and the pattern of the flashes it emits should be matched with the fault code (see below).
30. Turn the ignition OFF and remove the key.
31. Insert the second new key and turn the ignition ON. The indicator should now come on for two seconds, then begin to flash repeatedly four times. This indicates that the system has registered the second new key.
32. Turn the ignition OFF and remove the key.
33. The new ICU will only register two new keys at this stage. If you have a third key that you want to register, refer to Steps 4 to 10 to register it, noting that you will need the special tool mentioned therein.
34. Check that both newly registered keys, can start the motorcycle.
Fault diagnosis
Note: To enter the fault diagnosis mode ot the system you will need the Honda special tools (Part Nos. 07XMZ-MBW0100, 07YMZ-MCB0100 or 07XMZ-MBW0101, and 07YMZ-0010100) which are a wiring loom adapter that plugs into the ignition pulse generator wiring connector. If this tool is not available, fault diagnosis must be carried at a Honda dealer with the special tool.
35. There are two fault diagnosis modes, one for if there is a fault during normal use. and one for a fault that occurs when registering a new key. Make sure you refer to the correct table below when matching the fault code pattern.
36. If the Indicator light has come on and stayed on during normal use, remove the fuel tank (see Chapter 4). Disconnect the 2-pin ignition pulse generator wiring connector. Connect the special tool wiring connector to the ICU side of the connector, then connect the red coloured clip of the tool to the battery positive (+) terminal and the green coloured clip to the battery negative (-) terminal.
37. Turn the ignition switch ON. The indicator light in the tachometer will come on for ten seconds, then start to flash. This means it has entered diagnostic mode, and the pattern ol the flashes indicates the fault that has occurred. The pattern repeats continuously. Match the pattern with the fault codes shown below, making sure you refer to the relevant table. If the indicator stays on after ten seconds and does not flash, then there is no fault logged in the system.
Troubleshooting procedure
Indicator light does not come on when ignition switched ON
38. Check the fuses (see Chapter 9).
39. If the fuses are good, check whether the neutral and oil pressure warning lights have come on.
40. If the lights have not come on, remove the fairing (see Chapter 8). Disconnect the instrument cluster wiring connectors. Using a voltmeter, connect the positive (+) probe to the black wire terminal on the loom side of the 6-pin connector and the negative (-) probe to the green wire terminal on the loom side of the 9-pin connector. With the ignition ON there should be battery voltage. If voltage is present, the indicator unit is faulty and must be replaced with a new one (see Chapter 9). If there is no voltage, check for continuity in the wiring, referring to the Wiring Diagrams at the end of Chapter 9. The green wire goes to earth (ground).
41. If the lights have come on, remove the left-hand side panel (see Chapter 8). Disconnect the ICU 22-pin wiring connector. Using a voltmeter, connect the positive (+ve) probe to the white/red wire terminal on the loom side of the indicator connector and the negative (-ve) probe to earth (ground). Turn the ignition ON - there should be battery voltage.
42. If there was no voltage, using a voltmeter, connect the positive (+) probe to the white/red wire terminal on the loom side of the indicator connector and the negative (-) probe to the green wire terminal on the loom side of the instrument cluster connector. Turn the ignition ON - there should be no voltage for two seconds, then there should be battery voltage. If there is no voltage after two seconds, check for continuity in the wiring, referring to the Wiring Diagrams at the end of Chapter 9. The green wire goes to earth (ground). If no voltage is present, the indicator unit is faulty and must be replaced with a new one (see Chapter 9). If there is voltage, check for continuity in the white/red wire between the indicator unit and the ICU.
43. If there is voltage in Step 41, disconnect the ICU wiring connector. Using a voltmeter, connect the positive (+) probe to the blаск/white wire terminal on the loom side of the ICU connector and the negative (-) probe to earth (ground). Turn the ignition ON - there should be battery voltage. If there is no voltage, check for continuity In the blаск/white wire, referring to the Wiring Diagrams at the end of Chapter 9. If voltage is present, check for continuity to earth (ground) in the green wire. If the wiring is good, check the ICU connector for loose, damaged or corroded terminals. If the connector is good, then the ICU could be faulty, and should be checked by a Honda dealer.
Indicator light stays on when ignition switched ON
44. Check Ihat none of the other registered keys are close to the receiver. If they are, remove them and try the ignition again.
45. Turn the ignition ON with a spare key and check the indicator light, which should come on for two seconds, then go out. If It does, the first key is faulty. If it doesn't, perform the fault diagnosis procedure described above. If a fault code is displayed, use the appropriate table to determine the fault and the solution.
46. If no fault code is displayed, or the system does not go into fault diagnosis mode, remove the seat (see Chapter 8). Disconnect the ICU 22-pin black wiring connector. Using a voltmeter, connect the positive (+) probe to the white/red wire terminal on the loom side of the indicator connector and the negative (-) probe to earth (ground). Turn the ignition ON -there should be battery voltage. If there is no voltage, check for continuity in the white/red wire between the ICU and the indicator unit.
47. If there is voltage, check for continuity in the yellow and white/yellow wires between the ICU and the ignition pulse generator, referring to the Wiring Diagrams at the end of Chapter 9. If there is no continuity, trace the fault and repair or replace the wiring as necessary. If there is continuity, the ICU could be faulty and should be taken to a Honda dealer for assessment.
Fault code indicated by flash pattern
48 If the 'two short, two long' flash pattern has been indicated during the fault diagnosis procedure, remove the fairing (see Chapter 8). Trace the wiring from the receiver on the ignition switch and disconnect it at the connector. Using a voltmeter, connect the positive (+) probe to the yellow/red wire terminal on the loom side of the receiver connector and the negative (-) probe to earth (ground). Turn the ignition ON - there should be approximately 5 volts present. If there is no voltage, check for continuity in the yellow/red wire between the ICU and the receiver, and repair or replace the wiring if there is no continuity.
49. If there is 5 volts present, check for continuity to earth (ground) in the green/orange wire, and repair or replace the wiring if there is no continuity.
50. If the wiring is good, using a voltmeter, connect the positive (+) probe to the pink wire terminal on the loom side of the receiver connector and the negative (-) probe to earth (ground). Turn the ignition ON - there should be approximately 5 volts present. If there is, the receiver is faulty.
51. If there is no voltage, check for continuity in the orange/blue and pink wires between the ICU and the receiver, and repair or replace the wiring if there is no continuity between the connectors, or if there is continuity in either to earth (ground). If the wiring is good, the receiver is faulty.
Replacement
52. To replace the receiver, remove the fairing (see Chapter 8). Trace the wiring from the receiver on the ignition switch and disconnect It at the connector. Undo the screws securing the receiver around the ignition switch and remove the receiver, noting how it fits. If you don't have the correct tools to easily access the screws, follow the procedure for removing the top yoke in the ignition switch replacement Section in Chapter 9.
53. To replace the ICU see Section 5.
