SERVICE PROCEDURE:
1.
Attach a GDS and select DTC Analysis and A/T menu. Record the DTC and description.
Delete the DTC.
2.
From the GDS home screen, select Data Analysis and A/T menu and the solenoid parameters
shown below. If the solenoids show:
 Continuous and changing output while driving, the wiring currently has no open/short
circuits. Go to Step 4.
 No continuous and changing output, go to Step 3.
3.
Visually check the wiring harness between the TCM and transmission for a damaged wire or
connector. Check for an open/short circuit.
 If so, repair or replace the ECM control harness and drive the vehicle to confirm the repair.
 If no damage is found, go to Step 4.
4.
Record the audio preset stations and disconnect the negative battery terminal.
