A diagnostic routine is integrated in the control module which tests the control module and the electrical components of the airbag system. If a fault is
detected, the SRS malfunction indicator lamp (A1e15) does not go out after not more than 20 seconds. The faults detected are stored and can be
retrieved as a pulse readout using the malfunction indicator lamp (A1e15) or as a digital readout using a pulse counter. See Diagnosis Manual Body for
testing.
Note regarding pulse readout
The digits from 1-10 appear in the display of the pulse counter.
The digit 1 means that no system fault is stored. All the other digits are assigned to a particular type of fault. If there are several faults in the system, the
fault with the lowest pulse number is indicated first.
-
If the battery voltage LED comes on after connecting the pulse counter, the pulse counter and voltage supply for pulse counter are in proper order.
-
If the first digit again appears during the test after at least two or more pulse readouts (digits), all the faults have been displayed.
