STEP 3. Resistance measurement at the stoplight connectors (ground terminals).
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Measure the resistance between the rear combination light (stoplight: LH) connector (ground terminal) and ground.
(3) Measure the resistance between the rear combination light (stoplight: RH) connector (ground terminal) and ground.
(4) Measure the resistance between the high-mounted stoplight connector (ground terminal) and ground.OK: The resistance should be 2 ohms or less
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 ). Go to Step 4.
