1 CHECK CRUISE SET INDICATOR LIGHT CIRCUIT. Turn the ignition switch to OFF. Disconnect the combination meter harness connector. Measure the voltage between harness connector terminal and chassis ground. Connector & terminal (i12) No. 3 (+) - Chassis ground (-):	Is the voltage more than 10 V?	Go to step 2.	Check the harness for open or short between combination meter and ignition relay.
2 CHECK CRUISE SET INDICATOR LIGHT CIRCUIT. Turn the ignition switch to OFF. Disconnect the cruise control module harness connector. Measure the resistance between cruise control module harness connector terminal and combination meter harness connector terminal. Connector & terminal (112) No. 61 - (B94) No. 3:	Is the resistance less than 10 Ω?	Go to step 3.	Repair the harness.
3 CHECK CRUISE SET INDICATOR LIGHT CIRCUIT. Ground the cruise control module harness connector terminal with a suitable wire. Connector & terminal (B94) No. 3 - Chassis ground:	Does the cruise set indicator light illuminate?	Replace the cruise control module.	Check the cruise set indicator light bulb in combination meter, and replace it if malfunction occurred. No malfunction found, replace the printed circuit of combination meter.
