DTC Confirmation Procedure

NOTE:

- If DTC other than aimed DTC are previously detected in DTC confirmation procedure, be sure to troubleshoot DTC previously detected.
- Check that the following conditions are satisfied when using this procedure.

- Battery voltage > 10.5 V

1) Turn ignition switch to ON position for 10 sec.

DTC Troubleshooting



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

2. CVT fluid temperature sensor signal 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 CVT fluid temperature sensor signal circuit (A1) is as follows.
- Insulation resistance of CVT fluid temperature sensor signal circuit is infinity between solenoid connector and vehicle body ground.
- Insulation resistance of wire harness is infinity between CVT fluid temperature sensor signal circuit terminal and terminal at solenoid connector.

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

3. CVT fluid temperature sensor check

Check CVT fluid temperature sensor. Testing and Inspection

Are they in good condition?
YES
Substitute a known-good TCM and recheck.
NO
Replace CVT fluid temperature sensor (CVT assembly).
