00538 - Reference Voltage : Signal too small
Possible Causes
- Common Causes
- Fuse(s) faulty
- Wiring and/or Connector(s) from/to Control Module faulty
- Control Module faulty
- Heating/Climate Control specific Causes
- Fuse(s) faulty
- Wiring and/or Connector(s) from/to Control Module for Heating/Climate Control (J255/J301) faulty
- Flap Motor/Position Sensor faulty
- Control Module for Heating/Climate Control (J255/J301) faulty
Possible Solutions
- Common Solutions
- Check/Replace Fuse(s)
- Check/Repair Wiring and/or Connector(s) from/to Control Module
- Check/Replace Control Module
- Heating/Climate Control specific Solutions
- Check/Replace Fuse(s)
- Check/Repair Wiring and/or Connector(s) from/to Control Module for Heating/Climate Control (J255/J301)
- Check/Replace Flap Motor/Position Sensor
- Perform Output Test
- Control Module for Heating/Climate Control (J255/J301)
Special Notes
- When found in Control Module for Heating/Climate Control (J255/J301):
- Disconnect the electrical Connectors to the Position Sensors one after another, erase Fault Codes and check Fault Codes again. If the "Reference Voltage" Fault Code is no longer recognized (and the Fault Code for the reappears after reconnecting), the applicable Flap Motor/Position Sensor must be replaced.
00538 - Reference Voltage : Faulty
Possible Causes
- Fuse(s) faulty
- Wiring and/or Connector(s) from/to Battery faulty
- Control Module faulty
Possible Solutions
- Check Fuse(s)
- Check Wiring and/or Connector(s) from/to Battery
- Check/Replace Control Module
Special Notes
- When found in Central Electronics Control Module (J519):
- Specifically check the (Ground) Wiring from the Central Electronics Control Module (J519) to the Battery.
