      Tech Tips


      • If the cruise control indicator light check result indicates a problem, proceed to troubleshooting for the combination meter assembly section.

      • If a malfunction occurs in the vehicle speed sensors, stop light switch assembly or other related parts during cruise control driving, the ECM activates the AUTO CANCEL function of cruise control and goes off the cruise control indicator light. At the same time, the malfunction is stored as a diagnostic trouble code.
