    • Disconnect: Parking Aid Sensor C4009.
    • Ignition ON.
    • NOTE: It is normal for the sensor open signal DTC B1B48:14 to set when carrying out this step. It can be ignored.

      Clear the DTCs. Repeat the on-demand self-test.

    • Is DTC B1B58:11 still present? 
    1. Yes  : GO to E3.
    2. No  : INSTALL a new LH outer parking aid sensor. REFER to PARKING AID SENSOR . CLEAR the DTCs. TEST the system for normal operation.
  3. E3 CHECK THE RH OUTER PARKING AID SENSOR FOR AN INTERNAL SHORT 
    • Ignition OFF.
    • Disconnect: Parking Aid Sensor C4011.
    • Ignition ON.
    • NOTE: It is normal for the sensor open signal DTC B1B44:14 to set when carrying out this step. It can be ignored.

      Clear the DTCs. Repeat the on-demand self-test.

    • Is DTC B1B58:11 still present? 
    1. Yes  : GO to E4.
    2. No  : INSTALL a new RH outer parking aid sensor. REFER to PARKING AID SENSOR . CLEAR the DTCs. TEST the system for normal operation.
  4. E4 CHECK THE LH INNER PARKING AID SENSOR FOR AN INTERNAL SHORT 
    • Ignition OFF.
    • Disconnect: Parking Aid Sensor C4010.
    • Ignition ON.
    • NOTE: It is normal for the sensor open signal DTC B1B50:14 to set when carrying out this step. It can be ignored.
