Ground the STI connector. Connect a LED test light or VOM between the Red/Black (+) and White/Yellow (-) wire terminals of the 6-pin Self-Test connector. Watch the VOM as each switch is activated. Record all test results.

DO NOT  depress the throttle or clutch, or engage the transmission, unless directed. Refer to the SWITCH MONITOR TEST PROCEDURES chart.
