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.
