Checking USB Compatibility

Checking USB compatibility

Self-test
Integrated Audio Module (IAM) diagnostic test for AUX-input can only detect faults when something is connected to it. Therefore the diagnostic test is only run when a self-test of the USB-input has been started. A fault code is set if the self-test detects a fault. To start self-test and check fault codes belonging to the USB-input, proceed as follows:
- Connect the USB test device (Software Download Media Device) to the USB port in the centre armrest support.
- Click on the VCT2000 symbol to start self-test of the control module.
- Go to the tab DIAGNOSTICS/DETAILS and click on Update to perform a new fault code read-out.
- Go to the tab DIAGNOSTICS/TROUBLESHOOT and check if fault codes belonging to the USB-unit have been set.









Is relevant fault code set?

No - Fault-tracing

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 - Exit fault-tracing

No - Attempt New Test

Attempt New Test - Self-test

-------------------------------------------------

Fault-tracing
Fault-trace according to diagnostic trouble code (DTC) instructions.

The customer's USB memory does not seem to be compatible with the integrated audio (IAM).
The Integrated Audio Module (IAM) is compatible with USB 2.0 Mass Storage Device in FAT32 format.

Note! Replacing the Integrated Audio Module (IAM) does not solve the problem.

Has the fault been remedied?

Yes - FAULT FOUND

No - Fault-tracing information
