STEP 1. Measure the resistance at the AWC-ECU connector.
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Resistance between AWC-ECU connector terminal SOL+, SOL- and body groundOK: No continuity
Is the check result normal?
Go to Step 3. Go to Step 2.
STEP 2. Check the wiring harness between electronic control coupling solenoid (center) connector and AWC-ECU connector terminal SOL+, SOL-.
STEP 3. Check of the electronic control coupling (center)
STEP 4. Check whether the DTC is stored again.
STEP 5. Check whether the DTC is stored again.
