Entry in fault memory - P0500 vehicle speed signal - malfunction
Check whether a malfunction or symptom is present at the customer.

If yes, work through the test module.

If no, clear this fault from the fault memory.

Explanation:

Possible cause of entry in fault memory:

In the event of undervoltage, ABS/ASC/DSC stops transmission of the speed signal earlier than DME. Thus DME lacks the signal for its function and this fault memory is set.

Action:

Check the battery and voltage supply.
