Pinpoint Test E: DTC B1B58:11

NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
  1. E1 CHECK THE CONNECTORS FOR CORRECT LATCHING AND THE BUMPER WIRING HARNESS FOR DAMAGE 
    • Inspect the PAM and sensor connectors for correct latching by pulling on the latched connector  .
    • Inspect the bumper wiring harness for opens, shorts, grounds, or corrosion.
    • Are the connectors correctly latched and the bumper wiring harness OK? 
    • Yes:  GO to  E2.
    • No:  Correctly LATCH the connectors or REPAIR or INSTALL a new bumper wiring harness. CLEAR the DTCs. TEST the system for normal operation.
  2. E2 CHECK THE LH OUTER PARKING AID SENSOR FOR AN INTERNAL SHORT 
    • Ignition OFF.
    • Disconnect: Parking Aid Sensor C4009.
    • Ignition ON.
    • Clear the DTCs. Repeat the on-demand self-test.
      NOTE: It is normal for the sensor open signal DTC B1B48: 14 to set when carrying out this step. It can be ignored.
    • Is DTC B1B58: 11 still present? 
    • Yes:  GO to  E3.
    • 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.
    • Clear the DTCs. Repeat the on-demand self-test
      NOTE: It is normal for the sensor open signal DTC B1B44: 14 to set when carrying out this step. It can be ignored.
    • Is DTC B1B58: 11 still present? 
    • Yes:  GO to  E4.
    • 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.
    • Clear the DTCs. Repeat the on-demand self-test.
    • Is DTC B1B58: 11 still present? 
    • Yes:  GO to  E5.
    • No:  INSTALL a new LH inner parking aid sensor. REFER to PARKING AID SENSOR . CLEAR the DTCs. TEST the system for normal operation.
  5. E5 CHECK THE RH INNER PARKING AID SENSOR FOR AN INTERNAL SHORT 
    • Ignition OFF.
    • Disconnect: Parking Aid Sensor C4012.
    • Ignition ON.
    • NOTE: It is normal for the sensor open signal DTC B1B46: 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? 
    • Yes:  GO to  E6.
    • No:  INSTALL a new RH inner parking aid sensor. REFER to PARKING AID SENSOR . CLEAR the DTCs. TEST the system for normal operation.
  6. E6 CHECK THE PARKING AID SENSOR VOLTAGE SUPPLY CIRCUIT FOR A SHORT TO GROUND 
    • Ignition OFF.
    • Disconnect: PAM C4014  .
    • Measure the resistance between the PAM C4014-9, circuit LMP07 (BU/WH), harness side and ground  .

    • Is the resistance greater than 10,000 ohms? 
    • Yes:  GO to  E7.
    • No:  REPAIR the circuit. CLEAR the DTCs. TEST the system for normal operation.
  7. E7 CHECK THE PARKING AID SENSOR VOLTAGE SUPPLY CIRCUIT AND GROUND CIRCUIT FOR A SHORT TOGETHER 
    • Measure the resistance between the PAM C4014-9, circuit LMP07 (BU/WH)  , harness side and the PAM C4014-12, circuit RMP07 (GN/WH)  .

    • Is the resistance greater than 10,000 ohms? 
      • Yes:  GO to  E8.
      • No:  REPAIR the circuit in question. CLEAR the DTCs. TEST the system for normal operation.
  8. E8 CHECK FOR CORRECT PAM OPERATION 
    • Connect: All Disconnected Connectors.
    • Disconnect the PAM connector  .
    • Check for:
      • corrosion
      • damaged pins
      • pushed-out pins
    • Connect the PAM connector and make sure it seats correctly  .
    • Operate the system and determine if the concern is still present.
    • Is the concern still present? 
    • Yes:  INSTALL a new PAM  . REFER to PARKING AID MODULE (PAM) . TEST the system for normal operation.
    • No:  The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.

      CLEAR the DTCs. REPEAT the self-test.
