Checking wiring
-- Using a Multimeter, Check the Throttle Valve Control Module -J338- electrical harness connector for an open circuit.
| Throttle Valve Control Module -J338- electrical harness connector terminals | Measure To: |
|---|---|
| 1 | Ground connection in engine compartment, left |
| 2 | Fuse, (Refer to applicable wiring diagram for fuse positions). |
Specified value: 1.5 Ω Max.
If the specified value was Not obtained:
-- Check the wiring connection for an open or short circuit.
-- Check the wiring connection for damage, corrosion, loose or broken terminals.
-- If necessary, repair the faulty wiring connection and replace any open fuses
-- Go to Final procedures
If the specified value was obtained:
-- If no faults were found Replace the Throttle Valve Control Module -J338-.
-- Go to Final procedures
-- Remove the Motronic Engine Control Module (ECM) - J623 -.
-- Using a Multimeter, Check the Throttle Valve Control Module -J338- electrical harness connector to the Engine Control Module (ECM) - J623 - electrical harness connector T60 for an open circuit.
| Throttle Valve Control Module -J338- electrical harness connector terminals | Engine Control Module (ECM) - J623 - electrical harness connector T60 terminals |
|---|---|
| 3 | 30 |
| 4 | 11 |
Specified value: 1.5 Ω Max.
If the specified value was Not obtained:
-- Check the wiring connection for an open circuit, short circuit to Battery positive or Ground
-- Check the wiring connection for damage, corrosion, loose or broken terminals.
-- If necessary, repair the faulty wiring connection.
-- Go to Final procedures
If the specified value was obtained:
-- Replace the Engine Control Module (ECM) - J623 -.
Final procedures
After 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 .
