Observe all safety precautions: SAFETY PRECAUTIONS 

View clean working conditions: CLEAN WORKING CONDITIONS 

Perform a preliminary check to verify the condition: PRELIMINARY CHECK .

Special Tools And Workshop Equipment 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 appropriate 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-.

-- 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 Appropriate Wiring Diagrams for Pin locations.

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 appropriate 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 .
2. If necessary, erase the DTC memory. Refer to DIAGNOSTIC MODE 04 - ERASE DTC MEMORY .
3. If the DTC memory was erased, generate readiness code. Refer to READINESS CODE .
