CHECKING DOOR SWITCH
| Step | Check | Yes | No |
|---|---|---|---|
| 1 : CHECK DOOR SWITCH CIRCUIT. Measure the voltage between the keyless entry control unit harness connector terminal and chassis ground. Connector & terminal Front and rear side door: (B176) No. 10 (+) - chassis ground (-): Rear gate: (B176) No. 9 (+) - 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 keyless entry control unit harness connector terminal and chassis ground. Connector & terminal Front and rear side door: (B176) No. 10 (+) - chassis ground (-): Rear gate: (B176) No. 9 (+) - chassis ground (-): |
Is the voltage more than 10 V when all doors and rear gate are closed? | The door switch is OK. | Go to step 3. |
3 : CHECK DOOR SWITCH.
Terminals Door switch No. 1 - No. 3: Rear gate latch switch No. 1 - No. 2: |
Is the resistance more than 1 Mohm when the door switch is depressed? | Go to step 4. | Replace the door switch. |
| 4 : CHECK DOOR SWITCH. Measure the resistance between the door switch terminals. Terminals Door switch No. 1 - No. 3: Rear gate latch switch No. 1 - No. 2: |
Is the resistance less than 1 ohm when the door switch is released? | Check the harness for open circuits and shorts between the keyless entry control unit and door switch. | Replace the door switch. |
