Cruise Control Main Switch
- Remove Traction Control System (TCS) and cruise control main switch from driver's switch panel. Disconnect main switch 5-pin connector. With switch in OFF position, continuity should exist between switch terminals No. 1 and 2, and between terminals No. 4 and 5. See Fig 1 . Go to next step.
- With main switch in ON position, continuity should exist between switch terminals No. 1 and 2, and between terminals No. 3, 4 and 5. See WIRING DIAGRAMS . If continuity is not as specified, check for defective bulbs and replace as necessary. If both bulbs are okay, replace TCS/cruise control main switch.
