| Fault code No. | 36 |
| Symptom | Ignition coil #4 primary lead malfunction |
| Fail-safe action | Engine startup: Possible (depending on the number of failed cylinders) |
| Riding: Possible (depending on the number of failed cylinders) | |
| Diagnostic monitoring code No. | D:33 |
| Meter display | Actuates the cylinder-#4 ignition coil five times at one-second intervals. Illuminates the engine trouble warning light. |
| Checking method | Check the spark five times. Connect an ignition checker. |
| Item/components and probable cause | Check or maintenance job | Sensor inspection procedure | |
| 1 | Connection of ignition coil coupler. Check the connection of the coupler is secure. Remove the coupler, and check each pin (for bending, wear, or locking). | Poor connection → Connect it securely or repair/replace the wire harness. | Start and idle the engine for approximately 5 seconds. Then, check the fault code indication. No fault code indicated. → Recovered. Fault code indicated. → Check the next step. |
| 2 | Connection of main harness ECU coupler. Check the connection of the coupler is secure. Remove the coupler, and check each pin (for bending, wear, or locking). | Poor connection → Connect it securely or repair/replace the wire harness. | Start and idle the engine for approximately 5 seconds. Then, check the fault code indication. No fault code indicated. → Recovered. Fault code indicated. → Check the next step. |
| 3 | Continuity of wire harness | Open or short circuit → Replace the wire harness. Gray/Green-Gray/Green | Start and idle the engine for approximately 5 seconds. Then, check the fault code indication. No fault code indicated. → Recovered. Fault code indicated. → Check the next step. |
| 4 | Ignition coil installation status | Check the connection of the coupler is secure. Make sure that the mounting position is correct. | Start and idle the engine for approximately 5 seconds. Then, check the fault code indication. No fault code indicated. → Recovered. Fault code indicated. → Check the next step. |
| 5 | Ignition coil malfunction (Check the resistance of ignition coil #4.) | Refer to "Checking the ignition coils". Ignition coil inspection method | Start and idle the engine for approximately 5 seconds. Then, check the fault code indication. No fault code indicated. → Recovered. Fault code indicated. → Check the next step. |
| 6 | ECU malfunction | Check in the diagnostic mode (Code No. 33). If not ignited, replace the defective ECU. |
