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 Oil Temperature
Sensor. If the sensor shows:
 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 ECU 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 ECU control harness and drive the vehicle to confirm
the repair.
 If no damage or open/short circuit is found, go to Step 4.

4.

Refer to the DTC recorded in Step 1 and follow the repair procedure shown below:
