View clean working conditions: CLEAN WORKING CONDITIONS
Prior to repair work, perform a preliminary check to verify the condition. Refer to PRELIMINARY CHECK .
Use only gold-plated terminals when servicing any component with gold-plated electrical harness connector terminals.
See Appropriate Wiring Diagram Information for component locations and connector views.
Special Tools And Workshop Equipment Required
- Multimeter.
- Wiring diagram.
Test Requirements
- The ignition switched Off.
Start Diagnosis
-- Disconnect the Intake Flap Motor -V157- electrical harness connector.
Checking Voltage
-- Switch the ignition On.
-- Using a multimeter, measure voltage supply between connector terminals 1 to 3 for voltage. Refer to Appropriate Wiring Diagrams for Pin locations.
Specified Value: Approx. 5 V.
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 The Specified Value Was Obtained:
-- Ignition still On.
-- Using a multimeter, measure voltage supply between connector terminals 4 to 5 for voltage.
Specified Value: Near 4.35 V.
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 The Specified Value Was Obtained:
-- Using a multimeter, measure voltage supply between connector terminals 2 to 3 for voltage.
-- Switch the ignition Off.
Specified Value: Approx. 5.01 V.
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 Intake Flap Motor -V157-. 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 Intake Flap Motor -V157- electrical harness connector to the Engine Control Module (ECM) -J623- electrical harness T60 connector for resistance. Refer to Appropriate Wiring Diagrams for Pin locations.
| Intake Flap Motor -V157- electrical harness connector terminal | Engine Control Module (ECM) -J623- electrical harness connector T60 terminals |
|---|---|
| 1 | 10 |
| 2 | 27 |
| 3 | 51 |
| 4 | 35 |
| 5 | 50 |
Specified Value: 1.5 Ω Max.
If The Specification 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:
- Check the DTC memory. Refer to DIAGNOSTIC MODE 03 - READ DTC MEMORY .
- If necessary, erase the DTC memory. Refer to DIAGNOSTIC MODE 04 - ERASE DTC MEMORY .
- If the DTC memory was erased, generate readiness code. Refer to READINESS CODE .
