Inspection Method For Sensors

  1. Connect the M-MDS to the DLC-2.
  2. Switch the ignition ON (engine off).
    NOTE:
    • If the engine starts and runs, perform the following steps during idle.
  3. Access the PIDs for the switch you are inspecting.
  4. Shake the sensor slightly with your finger.
    • If the PID value is unstable or a malfunction occurs, check for a poor connection or a poorly mounted sensor or both.
