Signal Missing

Signal missing

Checking the function of the driver information module (DIM)
Check the power supply for the driver information module (DIM) by switching on the ignition.
The lighting in the instrument panel must light up.

Does the lighting in the driver information module (DIM) light up?

Yes - Checking communication with the driver information module (DIM)

No - Checking the power supply and ground for the driver information module (DIM)

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

Checking the power supply and ground for the driver information module (DIM)
Check that the fuse for the control module is intact.
Check the power supply and ground terminal for the driver information module (DIM) as follows.
Remedy as necessary.

Was a fault detected?

Yes - Checking the function of the driver information module (DIM)

No - Signal Missing - General Information

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

Checking communication with the driver information module (DIM)

Hint: The CAN communication with the control module is probably OK if the control module ID can be read off. The fault is probably intermittent and may therefore be difficult to locate.




- Try to communicate with the driver information module (DIM) by reading off the control module ID
- Click on the symbol for VCT2000 to begin reading off

Checking the function of the driver information module (DIM)

Hint: After carrying out the repair, check that the fault has been remedied.








- Ignition off
- Reconnect the connectors. Reinstall the components
- Ignition on.
Check the power supply for the driver information module (DIM) by switching on the ignition.
The lighting in the instrument panel must light up.
If the above works, start the engine and check that the indicator lamps go out correctly and that the tachometer reacts to changes in engine speed.

Is the driver information module (DIM) working?

Yes - FAULT FOUND

No - Fault-tracing information

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

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 - Exit Fault-tracing

No - Attempt New Test
