CRUISE CONTROL SYSTEM DIAGNOSIS SYSTEM


  1. DESCRIPTION

    The ECM controls the cruise control system of the vehicle. The data and DTCs relating to the cruise control system can be read from the DLC3 of the vehicle. If either DTC or CRUISE OK is not displayed on the multi-information display on the combination meter when checking for DTCs, there may be a problem with either the combination meter or the CAN communication system. Use the intelligent tester to check and solve the problem.

    Tech Tips

    If a vehicle speed sensor, stop light switch or any other related part malfunctions, the ECM cancels cruise control operation automatically.
