Honda Fit/Jazz - Interlock System - Shift Lock System Circuit Troubleshooting (CVT)
Interlock System - Shift Lock System Circuit Troubleshooting
1. | Press the brake pedal. Are the brake lights ON? YES - Go to 2. NO - Repair faulty brake pedal circuit.n |
2. | Disconnect the battery negative terminal. |
3. | Disconnect PCM connectors A (31P) and E (31P). |
4. | Connect the battery negative terminal. |
5. | Press the brake pedal, and measure the voltage between PCM connector terminals E22 and A23 or A24. Is there battery voltage? YES - Release the brake pedal, then go to 6. NO - Repair open in the wire between PCM connector terminal E22 and the brake pedal position switch.n |
6. | Disconnect the gauge assembly connector B (14P). |
7. | Press the brake pedal, and measure the voltage between gauge assembly connector terminal B6 and body ground. Is there battery voltage? YES - Release the brake pedal, then go to 8. NO - Repair open or short in the wire between gauge assembly connector terminal B6 and the brake pedal position switch.n |
8. | Disconnect the battery negative terminal. |
9. | Connect PCM connectors A (31P), E (31P), and gauge assembly connector B (14P). |
10. | Reconnect the battery negative terminal. |
11. | Remove the center console, and disconnect the shift lock solenoid connector. |
12. | Turn the ignition switch ON (II). |
13. | Measure the voltage between shift lock solenoid connector terminal No. 3 and body ground. Do not press the accelerator pedal. Is there battery voltage? YES - Go to 14. NO - Check for blown No. 16 fuse in under-hood fuse/relay box. If the fuse is OK, repair open or short in the wire between the shift lock solenoid connector and the under-hood fuse/relay box.n |
14. | Press the brake pedal, and measure the voltage between shift lock solenoid connector terminals No. 3 and No. 4. The shift lever must be in P position. Is there battery voltage? YES - Go to 15. NO - Go to 16. |
16. | Turn the ignition switch OFF. |
17. | Disconnect gauge assembly connector B (14P). |
18. | Check for continuity between gauge assembly connector terminal B1 and shift lock solenoid connector terminal No. 4. Is there continuity? YES - Go to 19. NO - Repair open in the wire between gauge assembly connector terminal B1 and the shift lock solenoid connector.n |
