Other information
- To access and replace the ultrasonic sensor control module, see Ultrasonic or glass breakage control module Ultrasonic Or Glass Breakage Control Module
- To access and replace the VGLA control module, see VGLA-control module VGLA-Control Module
- The voltage between connector terminal #1 on the ultrasonic sensor control module and ground should be battery voltage.
Was a fault detected?
Yes - Verification
No - Replacing the component
-------------------------------------------------
Replacing the component
Try a new ultrasonic sensor control module.

Verification
Hint: After carrying out the repair, check that the fault has been remedied as follows:
- Remove the key from the ignition switch
- Ensure that all doors and hatches are shut, including the hood and the trunk lid or tailgate
- Lock the car using the remote control to activate the alarm. Wait approximately 30 seconds. Unlock the car again
- Ignition on.
Read off diagnostic trouble code (DTC) status.
The status should display intermittent fault.
Does the status display an intermittent fault?
Yes - FAULT FOUND
No - Fault-tracing information

Information
Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
Do you want to exit fault-tracing?
Yes - FAULT-TRACING FAILED
No - Attempt New Test
