Checking loudspeaker element
Fault-tracing
Note! This fault tracing only applies to vehicles with Premium Sound audio equipment.
To determine whether a loudspeaker element works or not, it is appropriate to activate a test sequence that sends sent frequencies to all loudspeakers. The Audio module (AUD) can detect a defective loudspeaker element after the test sequence.
Carry out as follows to check the loudspeaker elements:
Note! The test sequence consists of high tones. Therefore, do not go near the speakers during the test.
- Press the symbol for VCT2000 in order to start the test sequence.
- Read off the result.

Fault-tracing information
Use the following information and general checks during fault-tracing.
Note! Check that the fuses are intact. For locations, see the instruction manual, cover for fuse box, fuse ratings or similar.
1. Check, if possible, relevant functions in the vehicle using buttons/controls/test drives to determine the status of the fault.
Note! If the vehicle does not show any of the given symptoms in the diagnostic trouble code information (DTC), this may mean that the fault is intermittent or that the control module is not detecting the fault at this moment.
2. Use the diagnostic trouble code's frozen values, status identifiers and counter to determine the operating conditions when the fault was detected, the fault's current status and any degree of intermittence of the fault.

Fault-tracing
Check if similar diagnostic trouble codes are stored in one or any of the other loudspeakers.
Are there similar DTCs in several loudspeakers?
Yes - Rectify in the following order
No - Rectify in the following order
-------------------------------------------------
Rectify in the following order:
1. Check the connectors to the control module. Check for contact resistance, loose connections and oxidation.
2. Check the connector to the loudspeaker. Check for contact resistance, loose connections and oxidation.
3. Check relevant signals using wiring diagram, signal specification and breakout box.
4. Perform a visual inspection of the cable between the control module and loudspeaker. If necessary, install a new cable.
5. Check the loudspeaker.

Fault-tracing
Rectify in the following order:
1. Use VIDA Vehicle communication. Read off the parameters, activate components and functions, carry out quick tests and checking routines for the diagnostic trouble codes to identify the fault.
2. Check relevant components according to Component specifications.
3. Remedy as necessary.
Note! More information is available in Design and function.
