1. Check:
Fault code number:
- a. Check the fault code number displayed on the meter.
- b. Identify the faulty system with the fault code.
- c. Identify the probable cause of the malfunction.
- 2. Check and repair the probable cause of malfunction.
| Fault code No. | No fault code No. |
| Check and repair. Refer to "Troubleshooting details". Monitor the operation of the sensors and actuators in the diagnostic mode. Refer to "Sensor operation table" and "Actuator operation table". | Check and repair. |
3. Perform fuel injection system reinstatement action.
Refer to "Reinstatement method" of table in "Troubleshooting details".
4. Turn the main switch to "OFF" and back to "ON", then check that no fault code number is displayed.
If fault codes are displayed, repeat steps (1) to (4) until no fault code number is displayed.
5. Erase the malfunction history in the diagnostic mode. Refer to "Sensor operation table (Diagnostic code No. D:62)".
Turning the main switch to "OFF" will not erase the malfunction history.
The engine operation is not normal but the engine trouble warning light does not come on.
1. Check the operation of following sensors and actuators in the Diagnostic mode. Refer to "Sensor operation table" and "Actuator operation table".
- D:01: Throttle position sensor signal 1 (throttle angle)
- D:13: Throttle position sensor signal 2 (throttle angle)
- D:14: Accelerator position sensor signal 1 (throttle angle)
- D:15: Accelerator position sensor signal 2 (throttle angle)
- D:30: Cylinder-#1 ignition coil
- D:31: Cylinder-#2 ignition coil
- D:32: Cylinder-#3 ignition coil
- D:33: Cylinder-#4 ignition coil
- D:36: Primary injector #1
- D:37: Primary injector #2
- D:38: Primary injector #3
- D:39: Primary injector #4
- D:40: Secondary injector #1
- D:41: Secondary injector #2
- D:42: Secondary injector #3
- D:43: Secondary injector #4
- D:48: Air induction system solenoid
If a malfunction is detected in the sensors or actuators, repair or replace all faulty parts. If no malfunction is detected in the sensors and actuators, check and repair inner parts of the engine.
