CHECKING DOOR SWITCH
| Step | Check | Yes | No |
|---|---|---|---|
| 1 : CHECK DOOR SWITCH CIRCUIT. Measure the voltage between the security control unit harness connector terminal and chassis ground. Connector & terminal Front and rear door: (B93) No. 5 (+) - chassis ground (-): Rear gate: (B93) No. 4 (+) - chassis ground (-): |
Is the voltage 0 V when any door or rear gate is opened? | Go to step 2. | Go to step 3 . |
| 2 : CHECK DOOR SWITCH CIRCUIT. Measure the voltage between the security control unit harness connector terminal and chassis ground. Connector & terminal Front and rear door: (B93) No. 5 (+) - chassis ground (-): Rear gate: (B93) No. 4 (+) - chassis ground (-): |
Is the voltage more than 10 V when any door and rear gate are 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 No. 1 - No. 2: |
Is the resistance more than 1 Mohm 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 No. 1 - No. 2: |
Is the resistance less than 1 ohm when door switch is released? | Check the harness for open circuits and shorts between the security control unit and door switch. | Replace the door switch. |
