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.
