DOOR SWITCH
| Step | Check | Yes | No |
|---|---|---|---|
| 1 CHECK DOOR SWITCH CIRCUIT. Measure the voltage between the security control module harness connector terminal and chassis ground. Connector & terminal Front and rear door: (B93) No. 5 (+) - Chassis ground (-): Rear gate or trunk lid: (B93) No. 4 (+) - Chassis ground (-): |
Is the measured value less than 1.5 V when each door, rear gate or trunk lid is opened? | Go to step 2. | Go to step 3. |
| 2 CHECK DOOR SWITCH CIRCUIT. Measure the voltage between the security control module harness connector terminal and chassis ground. Connector & terminal Front and rear door: (B93) No. 5 (+) - Chassis ground (-): Rear gate or trunk lid: (B93) No. 4 (+) - Chassis ground (-): |
Does the measured value exceed the 10 V when all doors and rear gate or trunk lid is closed? | The door switch is OK. | Go to step 3. |
3 CHECK DOOR SWITCH.
Terminal Door switch: No. 1 - No. 3: Rear gate latch switch or trunk room light: No. 1 - No. 2: |
Is the measured value more than 1 MΩ when door switch is pushed? | Go to step 4. | Replace the door switch. |
| 4 CHECK DOOR SWITCH. Measure the resistance between the door switch terminals. Terminal Door switch: No. 1 - No. 3: Rear gate latch switch or trunk room light switch: No. 1 - No. 2: |
Is the measured value less than 1Ω when door switch is released? | Check the harness for open circuits and shorts between the security control module and door switch. | Replace the door switch. |
