Check Security Indicator Light Circuit

CHECKING STEPS REFERENCE

Step	Check	Yes	No
1 CHECK SECURITY INDICATOR LIGHT. Disconnect the security control module harness connector. Ground the harness connector terminal with a suitable wire. Connector & terminal (B93) No. 9 - Chassis ground:	Does the security indicator light illuminate?	Replace the security control module.	Go to step 2.
2 CHECK POWER SUPPLY FOR SECURITY INDICATOR LIGHT. Disconnect the connector from the combination meter. Measure the voltage between the combination meter harness connector terminal and chassis ground. Connector & terminal (i12) No. 7 (+) - Chassis ground (-):	Is the measured value more than 10 V?	Go to step 3.	Check the harness for open circuits and shorts between the combination meter and the fuse.
3 CHECK SECURITY INDICATOR LIGHT CIRCUIT. Measure the resistance between the combination meter harness connector terminal and security control module harness connector terminal. Connector & terminal (i12) No. 1 - (B93) No. 9:	Is the measured value less than 10Ω?	Replace the combination meter printed circuit.	Check the harness for open circuits and shorts between the combination meter and security control module.
