Check Door Switch

DIAGNOSTIC PROCEDURE CHART

Step Check Yes No
1 CHECK DOOR SWITCH CIRCUIT. 
Measure the voltage between the keyless entry control module harness connector terminal and the body ground.

Connector & terminal 

Front and rear door: 

(B176) No. 6 (+) - Chassis ground (-): 

Rear gate: 


(B176) No. 7 (+) - 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 keyless entry control module harness connector terminal and the body ground.

Connector & terminal 

Front and rear door: 

(B176) No. 6 (+) - Chassis ground (-): 

Rear gate: 

(B176) No. 7 (+) - 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. 
  1. Disconnect the door switch harness connector.
  2. Measure the resistance between door switch terminals.

    Terminals 

    Door switch No. 1 - No. 3: 

    Rear gate latch switch No. 1 - No. 2: 

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.

Terminals 

Door switch No. 1 - No. 3: 

Rear gate latch switch No. 1 - No. 2: 

Is the resistance less than 1 Ω when door switch is released? Check the harness for open circuits or shorts between the keyless entry control module and the door switch. Replace the door switch.
DIAGNOSTIC PROCEDURE CHART

Step Check Yes No
1 CHECK SECURITY INDICATOR LIGHT. 
  1. Disconnect the keyless entry control module harness connector.
  2. Connect the harness connector terminal to ground using a suitable lead wire.

    Connector & terminal 

    (B176) No. 15 - Chassis ground: 

Does the security indicator light illuminate? Replace the keyless entry control module. Go to step 2. 
2 CHECK POWER SUPPLY FOR SECURITY INDICATOR LIGHT. 
  1. Disconnect the connector from combination meter.
  2. Measure the voltage between the keyless buzzer harness connector terminal and the body ground.

    Connector & terminal 

    (i10) No. 8 (+) - Chassis ground (-): 

Is the voltage more than 10 V? Go to step 3.  Check the harness for open or short circuits between combination meter and fuse.
3 CHECK SECURITY INDICATOR LIGHT CIRCUIT. 
Measure the resistance between the combination meter harness connector terminal and keyless entry control module harness connector terminal.

Connector & terminal 

(i12) No. 4 - (B176) No. 15: 

Is the resistance less than 10 Ω? Replace the combination meter. Check the harness for open or short circuits between combination meter and keyless entry control module.
