Checking activation
-
Connect voltage tester e.g. V.A.G 1527 B with measuring probes and connector adapters from V.A.G 1594 A between terminal 2 (CMP sensor
signal) and terminal 1 (B+); the harness connector remains connected.
NOTE: Connector socket numbers are shown on the rear side of the connector.
-
Operate starter for a few seconds.
-

NOTE: Voltage testers do not go out completely during low current pick-up between activations by the ECM, but rather continue to glow a little and
then get significantly brighter during activation.
-
Switch ignition off.
If LED does not blink:
