Diagnosis With KDS

The body electrical system can be quickly diagnosed for failed parts by using vehicle diagnostic system (KDS).

The diagnostic system (KDS) provides the following information.

(1) Self diagnosis : Checks and displays the failure code (DTC)

(2) Current data : Checks the system input/output data state

(3) Actuation test : Checks the system operating condition

(4) Additional function : Other controls such as the system option and zero point

  1. Select the 'Car model' and the system to be checked in order to check the vehicle with the tester.
  2. Select the 'Body Control Module (BCM)' to check the driver seat or assist door module (DDM/ ADM).
  3. Select the "Current Data" menu to check the current state of the input/output data.

    The input/output data for the sensors corresponding to the driver seat or assist door module (DDM/ ADM) can be checked.
