CRUISE CONTROL SYSTEM DIAGNOSIS SYSTEM

  1. DESCRIPTION

    The hybrid vehicle control ECU 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. Use the GTS to check and solve the problem.

    Tip:

    If a vehicle speed sensor, stop light switch assembly or any other related part malfunctions, the hybrid vehicle control ECU cancels control of vehicle speed automatically.

    1. Check the battery voltage.

      Standard Voltage

      11 to 14 V

      If the voltage is below 11 V, replace or recharge the battery before proceeding to the next step.
