STEP 1. Front door lock actuator (driver’s side) check.
STEP 2. Resistance measurement at front door lock actuator (LH) connector (ground terminal).
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Measure the resistance between the door lock actuator (LH) connector (ground terminal) and ground.OK: The resistance should be 2 ohms or less
Is the check result normal?
Go to Step 4. Go to Step 3.
STEP 3. Check of open circuit in ground line between front door lock actuator (LH) connector and body ground.
STEP 4. Check of short to power supply, short to ground, and open circuit in DDUK line between ETACS-ECU connector and front door lock actuator (LH) connector.
STEP 5. Using scan tool (M.U.T.-III), check data list.
(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 Scan Tool (M.U.T.-III)
."
(2) Change the status of driver's door from unlocked to locked. | Item No. | Item name | Normal condition | 228 | Dr door unlock | ON → OFF |
|
Item No. | Item name | Normal condition |
228 | Dr door unlock | ON → OFF |
OK: Normal condition is displayed.
Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to use Troubleshooting/inspection Service Points - How to Cope with Intermittent Malfunction ). Replace the ETACS-ECU.
