-
Check the wiring from the Battery to the Transmission Control Module (TCM) (J217) electrical harness connector T52 terminal 3 for an open
circuit or a short circuit.
-
If necessary, repair the faulty wiring connection.
If the specified value was obtained:
Checking Ground (GND)
-
Using a Multimeter, check the Transmission Control Module (TCM) (J217) electrical harness connector T52 terminals 1 and 2 to Ground (GND)
connection on left headlight for resistance.
Specified value: 1.5 ohms
If the specification was not obtained:
-
Check the Transmission Control Module (TCM) (J217) electrical harness connector T52 terminals 1 and 2 to Ground (GND) connection on left
headlight for an open circuit or a short circuit.
-
If necessary, repair the faulty wiring connection.
If no malfunction is found in the wiring:
-
Erase the DTC memory. Refer to --> [ Diagnostic Mode 04 - Erase DTC Memory ] See: Powertrain Management/Computers and Control
Systems/Testing and Inspection/Scan Tool Testing and Procedures/Diagnostic Mode 04 - Erase DTC Memory.
-
Perform a road test to verify repair.
If the DTC does not return:
Repair complete, Generate readiness code. Refer to --> [ Readiness Code ] See: Powertrain Management/Computers and Control Systems/Testing and
Inspection/Monitors, Trips, Drive Cycles and Readiness Codes/Readiness Code.
-
End of diagnosis.
If the DTC does return and no malfunction is detected in the wiring and the voltage supply was OK:
-
Replace the Transmission Control Module (TCM) (J217). Refer to --> [ Transmission Control Module, Replacing ] .
After the repair work, the following work steps must be performed in the following sequence:
Final procedures
After the repair work, the following work steps must be performed in the following sequence:
1. Check the DTC memory. Refer to --> [ Diagnostic Mode 03 - Read DTC Memory ] See: Powertrain Management/Computers and Control
Systems/Testing and Inspection/Scan Tool Testing and Procedures/Diagnostic Mode 03 - Read DTC Memory.
2. If necessary, erase the DTC memory. Refer to --> [ Diagnostic Mode 04 - Erase DTC Memory ] See: Powertrain Management/Computers and
Control Systems/Testing and Inspection/Scan Tool Testing and Procedures/Diagnostic Mode 04 - Erase DTC Memory.
3. If the DTC memory was erased, generate readiness code. Refer to --> [ Readiness Code ] See: Powertrain Management/Computers and Control
Systems/Testing and Inspection/Monitors, Trips, Drive Cycles and Readiness Codes/Readiness Code.
