    Are DTCs other than B129C:96 or B129D:96 recorded? 

    1. Yes: DIAGNOSE the other DTCs  first. REFER to DTC CHART: PARKING AID MODULE (PAM) .
    2. No: GO to 2  .
  2. CHECK THE ACTIVE PARK ASSIST SENSOR OPERATION
    NOTE: Make sure the area around the vehicle is clear of anything that can activate the active park assist sensors.

    2. Carry out the azimuth system check. REFER to Azimuth System Check .
    3. Ignition ON.
    4. Press the active park assist switch.
    5. Monitor and record the PAM distance PIDs  while moving a test object into and out of the azimuth field at each of the sensors.
      PID Description
      FSL_DIST_ER Left active park assist sensor distance
      FSR_DIST_ER Right active park assist sensor distance

    Does the active park assist sensor detect the correct PID distance according to the general specifications? 

    1. Yes: The system is operating correctly at this time. The concern may have been caused by a dirty or blocked active park assist sensor.
    2. No: GO to 3  .
  3. INSTALL A KNOWN GOOD SENSOR
