CHECKING STEPS REFERENCE

Step Check Yes No
1 CHECK POWER SUPPLY. 
  1. Disconnect the keyless entry control module harness connector.
  2. Measure the voltage between the harness connector terminal and chassis ground.

    Connector & terminal 

    1. (B176) No. 14, No. 15 (+) - Chassis ground (-): 
Is the measured value more than 10 V? Go to step 2. Check the harness for open circuits and shorts between the keyless entry control module and fuse.
2 CHECK GROUND CIRCUIT. 
Measure the resistance between the harness connector terminal and chassis ground.
Connector & terminal 
  1. (B176) No. 11 - Chassis ground: 
Is the measured value less than 10 Ω? The power supply and ground circuit are OK. Repair the harness.
