Check Door Switch

DOOR SWITCH DIAGNOSTIC PROCEDURE

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 10V when each door or rear gate is closed? The door switch is OK. Go to step 3.
3 CHECK DOOR SWITCH. 
  1. Disconnect the door switch harness connector.
  2. 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: (D140) No. 3 - No. 4: 

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: (D140) No. 3 - No. 4: 

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.
