Ignition Coil: Description and Operation
Monitoring Procedure
With the following criteria met:
-
Engine not in the starting position
-
Misfire detection not operative
-
Engine speed greater than 2500 rpm
-
Battery voltage less than 10V
A hardware check is made on the coils when they are due to be energized in accordance with ignition timing. If they are not energized correctly a counter
is started; once this exceeds a set number of non-operations a failure judgement is made and the relevant DTC(s) P0351-P0358 will be flagged.
For DTCs P1367 & P1368 the checking criteria and judgement is the same, except that the hardware check is made on the coils relevant to each
amplifier.
Non-operations will result in a failure judgement for the affected amplifier.
