DTC Troubleshooting



1.
Was "CVT System Check" performed?
YES
Go to Step 2.
NO
Go to CVT System Check.

2. TCC solenoid valve drive circuit check

Turn off ignition switch and disconnect TCM and solenoid connectors.
Check for proper terminal connection to TCM and solenoid connectors.
If connections are OK, check that TCC solenoid valve drive circuit (A2) is as follows.
- Insulation resistance of wire harness is infinity between TCC solenoid valve drive circuit terminal and each terminal at solenoid connector.
- Circuit voltage of TCC solenoid valve drive circuit 0 - 1 V with ignition switch ON position.

Are they in good condition?
YES
Go to Step 3.
NO
Repair or replace defective wire harness.
