Testing



The Powertrain Control Module (PCM) regulates the individual ignition coils and checks their function via a separate diagnostic cable. A diagnostic trouble code is generated if the control module detects a faulty signal for an ignition coil.

  1. Fault symptoms may include:

    Malfunction indicator lamp (MIL) lit
     
    The engine not firing on all cylinders
     

  2.  

The Diagnostic Trouble Code (DTC) can help diagnose which ignition coil is involved.

Before servicing any vehicle, please be sure to read the precautions section, which deals with personal safety, prevention of component damage, and important points to take into consideration when servicing a motor vehicle.

When it is suspected that one or more spark plugs may not be firing and the spark plug wires (if used) do not seem to be at fault, this test offers a quick check to see if the ignition module and coil packs are producing spark voltage.


CAUTION
The DIS system produces extremely high voltages. Never disconnect or touch a system component while the engine is running or the key is in the RUN position. Furthermore, it is always safest to disconnect the negative battery cable before servicing any system components.

If a single coil pack is suspect from an initial spark test, switch the coil pack to the opposite position on the ignition module and check to see if the problem follows it. If the problem follows, the coil pack must be replaced.

If the formerly good coil pack does not produce spark when switched with the suspect coil on the module, and the suspect coil works in the new position, then the ignition module may be faulty and in need of replacement.

Using an ohmmeter, check the resistance across the coil towers. The reading should be 7,000-10,000 ohms.
