Operation CHARM: Car repair manuals for everyone.

4 = Test Sequence - Example From Instrument Cluster




- A test sequence test whether parts of the system are operating correctly. In the case of a fault, notes on detailed troubleshooting appear.

- Not all diagnostic programs have the test sequence integrated, but they will be extended in this respect in future versions.

Note:

There is a fault if the condition shown on the screen (= condition detected by the control unit) differs from the actual condition.

Example: ON is shown for terminal 15, but the vehicle's ignition is switched off (fault: short circuit to positive).
