Test procedure

- Perform a preliminary check to verify the customers complaint. Refer to => [ Preliminary Check ] Preliminary Check.

Start diagnosis

- Disconnect the Selector Lever Sensor System Control Module (J587) electrical harness connector.

Checking voltage

- Using a Multimeter, check the Selector Lever Sensor System Control Module (J587) electrical harness connector terminal 10 to Ground (GND) for voltage.

- Switch the ignition off.

Specified value: battery voltage.

If the specified value was not obtained:

- Check the Selector Lever Sensor System Control Module (J587) electrical harness connector terminal 10 to the Battery (A) the for an open circuit or short to Ground (GND).

- Check the wiring connection for damage, corrosion, lose or broken terminals.

- If necessary, repair the faulty wiring connection.

If the specified value was obtained:

- Using a Multimeter, check the Selector Lever Sensor System Control Module (J587) electrical harness connector terminal 9 to Ground (GND) for voltage.

Specified value: battery voltage.

If the specified value was not obtained:

- Check the Selector Lever Sensor System Control Module (J587) electrical harness connector terminal 9 to the Generator (GEN) (C) terminal L for an open circuit or short to Ground (GND).

- Check the wiring connection for damage, corrosion, lose or broken terminals.

- If necessary, repair the faulty wiring connection.

If the wiring and voltage were OK:

- Using a Multimeter, check the Selector Lever Sensor System Control Module (J587) electrical harness connector terminal 5 to Ground (GND) for voltage.

Specified value: battery voltage.

If the specified value was not obtained:

- Check the Selector Lever Sensor System Control Module (J587) electrical harness connector terminal 5 to the Generator (GEN) (C) terminal L for an open circuit or short to Ground (GND).

- Check the wiring connection for damage, corrosion, lose or broken terminals.

- If necessary, repair the faulty wiring connection.

If the wiring and voltage were OK:

Checking Ground (GND)

- Using a Multimeter, check the Selector Lever Sensor System Control Module (J587) electrical harness connector terminal 1 to Ground (GND) connection on right lower A pillar for resistance.

Specified value: 1.5 ohms Max.

If the specified value was not obtained:

- Check the Selector Lever Sensor System Control Module (J587) electrical harness connector terminal 1 to Ground (GND) connection on right lower A pillar for an open circuit or short to Battery (+).

- Check the wiring connection for damage, corrosion, lose or broken terminals.

- If necessary, repair the faulty wiring connection.

- Erase the DTC memory. Refer to => [ Diagnostic Mode 04 - Erase DTC Memory ] 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 ] Monitors, Trips, Drive Cycles and Readiness Codes.

- End diagnosis.

If the DTC does return and no malfunction is detected in the wiring and the voltage supply was OK:

- Replace the Selector Lever Sensor System Control Module (J587).

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 ] Diagnostic Mode 03 - Read DTC Memory.

2. If necessary, erase the DTC memory. Refer to => [ Diagnostic Mode 04 - Erase DTC Memory ] Diagnostic Mode 04 - Erase DTC Memory.

3. If the DTC memory was erased, generate readiness code. Refer to => [ Readiness Code ] Monitors, Trips, Drive Cycles and Readiness Codes.
