01549 - Supply Voltage for Parking Aid Sensor

01549 - Supply Voltage for Parking Aid Sensor: Short to Ground

Possible Symptoms

  • Malfunction Indicator Light (MIL) ON
  • Parking Aid not working

Possible Causes

  • Fuse(s) faulty
  • Wiring and/or Connector(s) from/to Parking Aid Sensor(s) faulty
  • Parking Aid Sensor(s) faulty

Possible Solutions

  • Check Fuse(s)
  • Check Wiring and/or Connector(s) from/to Parking Aid Sensor(s)
  • Check/Replace Parking Aid Sensor(s)
    • Check Measuring Value Blocks (MVB) for Supply Voltage

Special Notes

  • One faulty sensor can cause this DTC and drop the Sensor Voltage Supply MVB reading. Unplugging the front -or- rear wiring harness to eliminate 4 sensors at a time is advised during the diagnosis. Make sure to cycle the ignition off and back on before evaluating the MVBs. After the front -or- rear of the vehicle are determined to be problematic it is recommended to unplug the senors one at a time to see which one crashes the Sensor Voltage Supply MVB reading.
