Checking the Ignition Discharge Module

Checking The Ignition Discharge Module







^ Check visually that
^ the four rubber seals are intact
^ the four contact springs are OK
^ the connector is free from corrosion and moisture
^ Rectify as necessary.







^ Fit the test spark plug in the ignition discharge module.
^ Ground the spark plugs.
^ Position the ignition discharge module so that the spark plugs are inclined downwards and the oil in the ignition coils covers the HT outputs.
^ Activate the ignition trigger by selecting automatic activation of the ignition coil for the misfiring cylinder. Choose from the following activation commands on the diagnostic tool:

Ignition Coil Cyl 1
Ignition Coil Cyl 2
Ignition Coil Cyl 3
Ignition Coil Cyl 4

^ Select automatic activation.
^ Check whether the relevant test spark plug produces a spark. If necessary, compare it by activating another ignition coil.
