DOOR SWITCH CHECKING PROCEDURE CHART
| Step | Check | Yes | No |
|---|---|---|---|
| 1 CHECK DOOR SWITCH CIRCUIT. Measure the voltage between the body integrated unit harness connector terminal and chassis ground. Connector & terminal Front door RH: (i84) No. 32 (+) - Chassis ground (-): Front door LH: (i84) No. 19 (+) - Chassis ground (-): Rear door RH: (i84) No. 18 (+) - Chassis ground (-): Rear door LH: (i84) No. 31 (+) - Chassis ground (-): Rear gate: (i84) No. 17 (+) - Chassis ground (-): |
Is the voltage 0 V when each door or rear gate is opened? | Go to step 2. | Go to step 3. |
| 2 CHECK DOOR SWITCH CIRCUIT. Measure the voltage between the body integrated unit harness connector terminal and chassis ground. Connector & terminal Front door RH: (i84) No. 32 (+) - Chassis ground (-): Front door LH: (i84) No. 19 (+) - Chassis ground (-): Rear door RH: (i84) No. 18(+) - Chassis ground (-): Rear door LH: (i84) No. 31 (+) - Chassis ground (-): Rear gate: (i84) No. 17 (+) - Chassis ground (-): |
Is the voltage more than 10 V when each door or rear gate is closed? | The door switch is OK. | Go to step 3. |
3 CHECK DOOR SWITCH.
|
Is the resistance 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 door switch terminals. Connector & terminal (R12) Front RH door switch: (R9) Front LH door switch: (R16) Rear RH door switch: (R22) Rear LH door switch: No. 1 - No. 3: Rear gate latch switch (Wagon model): (D46) No. 1 - No. 2: |
Is the resistance less than 1 Ω, when door switch is released? | Check the harness for open or short between body integrated unit and door switch. | Replace the door switch. |
