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 PCM and transmission for a damaged wire or
open/short circuit. Check for a damaged pin or pin not fully inserted into the connector.
 If damage exists, repair or replace the control wiring and drive the vehicle to confirm the
repair.
 If no damage or open/short circuit, go to Step 4.
