DTC Troubleshooting


1. Was "CVT System Check" performed?
YES
Go to Step 2.
NO
Go to CVT System Check CVT System Check.
2. Lock-up / select switching 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 the following points.
Resistance of "A4" circuit: less than 1
Resistance of "A4" circuit between "C142" connector and ground: infinity
Resistance between "A4" circuit terminal and each terminal at "C142" connector: infinity
Voltage of "A4" 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. Lock-up / select switching solenoid valve check
