VEHICLE STABILITY CONTROL SYSTEM CHECK FOR INTERMITTENT PROBLEMS


  1. SYMPTOM SIMULATION

    Tech Tips

    The most difficult case in troubleshooting is when no symptoms occur. In such cases, a thorough customer problem analysis must be carried out. Then the same or similar conditions and environment in which the problem occurred in the customer's vehicle should be reproduced. No matter how experienced or skilled a technician may be, if he/she proceeds to troubleshoot without confirming the problem symptoms, he/she will likely overlook something important and make a wrong guess at some points in the repair operation. This leads to a standstill in troubleshooting.

      Vibration method: When vibration seems to be the major cause.

      Tech Tips

      Perform the simulation method only during the primary check period (for approximately 6 seconds after the ignition switch ON).


      1. Slightly vibrate the part of the sensor considered to be the problem cause with your fingers and check whether the malfunction occurs.

      2. Slightly shake the connector vertically and horizontally.

        Tech Tips

        Shaking the relays too strongly may result in open relays.

      3. Slightly shake the wire harness vertically and horizontally. The connector joint and fulcrum of the vibration are the major areas to be checked thoroughly.
