Check Power Supply And Ground Circuit

POWER SUPPLY REFERENCE

Step	Check	Yes	No
1 CHECK POWER SUPPLY. Disconnect the keyless entry control module harness connector. Measure the voltage between the harness connector terminal and chassis ground. Connector & terminal (B176) No. 2, No. 26 (+) - 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 (B176) No. 14 - Chassis ground:	Is the measured value less than 10 Ω?	The power supply and ground circuit are OK.	Repair the harness.
