Special tools, testers and auxiliary items required

• Multimeter

• Wiring diagram.

Start diagnosis

- The Exhaust Flap Control Module (J883) is located near the center of the vehicle in the exhaust pipe.

- Disconnect the Exhaust Flap Control Module (J883) electrical harness connector.

Checking voltage

- Switch the ignition On.

- Using a multimeter, measure voltage supply between connector terminals 1 to 3 for voltage.

Specified value: near 5 V.

- Using a multimeter, measure voltage supply between connector terminals 2 to 3 for voltage.

Specified value: near 5 V.

If any specified value was Not obtained:

- Check the wiring for a short circuit to Battery positive, Ground or high resistance.

- Check the wiring connections for damage, corrosion, loose or broken terminals.

- If necessary, repair the faulty wiring connection.

If the specified values were obtained:

- Using a multimeter, measure voltage supply between connector terminals 4 to 5 for voltage.

Specified value: near 4.35 V.

- Switch the ignition Off.

If the specified value was Not obtained:

- Check the wiring for a short circuit to each other, Battery positive, Ground or high resistance.

- Check the wiring connections for damage, corrosion, loose or broken terminals.

- If necessary, repair the faulty wiring connection.

If no malfunction is detected in the wiring and the voltage readings were correct:

- Replace the Exhaust Flap Control Module (J883). Refer to the service information for removal and installation procedures.

If no malfunction is detected in the wiring and the voltage readings were Not correct:

Checking wiring

- Remove the Engine Control Module (ECM) (J623). Refer to the Repair Information.

- Using a multimeter, check the Exhaust Flap Control Module (J883) electrical harness connector to the Engine Control Module (ECM) (J623) electrical harness T60 connector for resistance. Refer to Wiring Diagrams for Pin locations.

For 2010 Models:






For 2011> Models:






Specified value: 1.5 ohms Max.

If the specified value was Not obtained:

- Check the wiring for a short circuit to each other, Battery positive, Ground or high resistance.

- If necessary, repair the faulty wiring connection.

- Check the electrical harness connector for damage, corrosion, loose or broken terminals.

If no malfunction is detected in the wiring and the voltage readings were Not correct:

- Replace the Engine Control Module (ECM) (J623). Refer to the service information for removal and installation procedures.

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 Modes 01 - 09.

2. If necessary, erase the DTC memory. Refer to => [ Diagnostic Mode 04 - Erase DTC Memory ] Diagnostic Modes 01 - 09.

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