STEP 1. Scan tool (M.U.T.-III) other system DTC.
(1) caution | To prevent damage to scan tool (M.U.T.-III), always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool (M.U.T.-III). |
Connect scan tool (M.U.T.-III). Refer to "How to connect the Scan Tool (M.U.T.-III)
."
(2) Turn the ignition switch to the "ON" position.
(3) Check the ETACS DTC (Refer to GROUP 54A - Troubleshooting ). Is the DTC set?
Perform the relevant troubleshooting. Go to Step 2.
STEP 2. Check the battery.
STEP 3. Check the charging system.
STEP 4. Voltage measurement at AWD-ECU connector
STEP 5. Scan tool (M.U.T.-III) data list.
STEP 6. Measure the resistance at the AWD-ECU connector.
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Resistance between AWD-ECU connector terminal GND1 and body ground.OK: The resistance should be 2 ohms or less
Is the check result normal?
Go to Step 8. Go to Step 7.
STEP 7. Check the wiring harness between AWD-ECU connector terminal GND1 and body ground.
STEP 8. Measure the resistance at the AWD-ECU connector.
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Resistance between AWD-ECU connector terminal SOL+, SOL- and body groundOK: No continuity
Is the check result normal?
Go to Step 10. Go to Step 9.
STEP 9. Check the wiring harness between electronic control coupling solenoid connector and AWD-ECU connector terminal SOL+, SOL-.
STEP 10. Check of the electronic control coupling solenoid
STEP 11. Scan tool (M.U.T.-III) data list.
STEP 12. Check whether the DTC is set again.
