DTC Troubleshooting


1. Was "CVT System Check" performed?
YES
Go to Step 2.
NO
Go to CVT System Check CVT System Check.
2. TCC solenoid valve drive circuit check
Confirm that ignition mode of keyless push start system is in "OFF".
Disconnect "C142", "E19" and "E20" connectors.
Check for proper terminal connection to "C142", "E19" and "E20" connectors.
If connections are OK, check that TCC solenoid valve drive circuit (A3) is as follows.
Resistance between "A3" circuit terminal and each terminal at "C142" connector: infinity
Voltage of "A3" circuit: 0 - 1 V (with ignition mode of keyless push start system in "ON")
Are they in good condition?
YES
Go to Step 3.
NO
Repair or replace defective wire harness.
3. TCC solenoid valve check
Check resistance of TCC solenoid valve. Testing and Inspection
Is it in good condition?
YES
Substitute a known-good TCM and recheck DTC. Service and Repair
NO
Replace TCC solenoid valve (CVT assembly). CVT Assembly Dismounting and Remounting
