Checking wiring
-- Remove the Engine Control Module - J623 -. Refer to appropriate Service Information.
-- Using a Multimeter, check the Control Valve Control Module -J808- at electrical harness connector terminals to the Engine Control Module -J623- electrical harness connector T94 terminals for an open circuit according to the wiring diagram.
| Control Valve Control Module -J808- electrical harness connector terminals: | Engine Control Module -J623- electrical connector T94 terminals: |
|---|---|
| 1 | 63 |
| 3 | 38 |
Specified value: 1.5 Ω max.
If the specified value was Not obtained:
-- Check the wiring for a short circuit to Battery voltage or an open circuit.
-- If necessary, repair the faulty wiring connection.
-- Check the electrical harness connector for damage, corrosion, loose or broken terminals.
If the specified value was obtained:
If no malfunction is detected in the wiring and if the voltage supply was not OK:
-- Replace the Engine Control Module -J623-. Refer to appropriate Service Information.
-- Go to Final procedures.
-- Remove the Engine Control Module - J623 -. Refer to appropriate Service Information.
-- Using a Multimeter, Check the Control Valve Control Module -J808- electrical harness connector to the Engine Control Module -J623 - electrical harness connector T94 for an open circuit.

Final procedures
-- Reinstall the engine cover with air filter, if necessary. Refer to the appropriate Service Information.
-- 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 .
