Ignition Diagnostic Monitor (IDM), a signal which indicates that the primary side of the coil has
fired. This signal is received as a digital pulsewidth signal from the EDIS system which process
the high voltage flyback signal from the primary side coil.

The relationship between successive PIP events is ev aluated to determine whether the PIP signal is
rational. Too large a change in 3 successive PIP indicates a missing or noisy PIP signal (P0320 or P0321).
Then the CMP edge count is compared to the PIP e dge count. If the proper ratio of CMP events to PIP
events is not being maintained (for example, 1 CMP e dge for every 8 PIP edges for an 8-cylinder engine),
it indicates a missing or noisy CMP signal (P0340). Finally, the relationship between IDM edges and PIP
edges is evaluated. If there is not an IDM edge (co il firing) for every PIP edge (commanded spark event),
the PCM will look for a pattern of failed IDM events to determine which ignition coil has failed circuit
continuity (P0351-56).

Ignition System Check Operation:
DTCs P0320 / P0321 (CKP), P0340 (CMP), P0351 - P0358 (Coil Primary)
Monitor execution continuous
Monitor Sequence none
Monitoring Duration < 5 seconds

Typical ignition check entry conditions : Minimum Maximum
Engine RPM for CKP, CMP 200 rpm
Engine RPM for coil primary 200 rpm

Typical ignition check malfunction thresholds:
For PIP : Time between PIP edges : > 350 milliseconds
Ratio of current PIP period to last two periods : < 0.75 > 1.75
For CMP : Ratio of PIP events to CMP events: 4:1, 6:1, 8:1 or 10:1 based on engine cyl.
For coils : Ratio of PIP events to IDM events: 1:1


General Outputs

The Fuel Injectors are checked electrically for open and short circuit (P0201 to P0208).

The Idle Air Control (IAC) solenoid is checked electrically for open and shorts (P1504).

The Purge Solenoid or Vapour Management Valve output circuit is checked for opens and shorts (P0443).

Purge Solenoid / VMV Check Operation:
DTCsP0443
Monitor execution continuous (5 seconds to identify malfunction/obtain smart driver status)
Monitor Sequencenone
Monitoring Duration 5 seconds for electrical malfunctions

Typical Purge Solenoid / VMV component malfunction thresholds:
P0443 open / shorted at 0 and 100% duty cycle
