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, rear gate: 

(B176) No. 6 (+) - 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 module harness connector terminal and the body ground.

Connector & terminal 

Front and rear door, rear gate: 

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

Is the voltage more than 10 V when any 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 and shorts between the keyless entry control module and the door switch. Replace the door switch.
