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. 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 unit harness connector terminal and chassis ground.
Connector & terminal 
Front and rear side 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.
