Diagnosis information - DME V8 DFI

Bar ignition module on cylinder 1 - SoftShutDown

NOTE:
The bar ignition module cannot be tested as it is an active component.
If a faulty bar ignition module is diagnosed, the connection to the engine ground must be checked before replacing the module as otherwise a faulty engine ground connection will damage the new bar ignition module.

NOTE:
- If both a driver fault and >>SoftShutDown<< are entered, the driver fault is the cause.
- If only >>SoftShutDown<< is entered, excessive coil charging time is the cause.
