DTC P0768 DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P0768 |
Reduction timing solenoid valve circuit malfunction (open circuit/short circuit) |
| DETECTION CONDITION |
- Open circuit or short circuit in reduction timing solenoid signal system (while TCM monitors solenoid output voltage, the voltage that differs from the ON/OFF signal output by CPU in TCM is detected.)
Diagnostic support note:
- This is continuous monitor (CCM).
- MIL does not illuminate
- PENDING CODE is not available.
- FREEZE FRAME DATA is not available.
- O/D OFF indicator light flashes.
- DTC is stored in TCM memory.
|
| POSSIBLE CAUSE |
- Open circuit between reduction timing solenoid valve terminal A and TCM terminal 2G
- Short to ground between reduction timing solenoid valve terminal A and TCM terminal 2G
- Short to power between reduction timing solenoid valve terminal A and TCM terminal 2G
- Reduction timing solenoid valve malfunction
- Damaged connector between reduction timing solenoid and TCM
- TCM malfunction
