The alarm output is activated.    Note: The engine must be running in order for the above diagnostic codes to become active.Systems OperationBoth the master ECM and the slave ECM have internal power circuits that are used to energize the primary circuits for the ignition transformers. The master ECM energizes the primary circuits for the cylinders with an even number. The slave ECM energizes the primary circuits for the cylinders with an odd number. Each power circuit creates a signal of 108 volts. The signal goes to the primary circuits of the ignition transformers. The secondary circuits for the ignition transformers deliver high voltage (8,000 to 37,000 volts) to the spark plugs. The external ignition wiring is continuous from the ECM connector to the bulkhead connectors that are located on the front face of the engine. The ignition wiring is inside the engine from the bulkhead connector to the individual transformers.Some power circuits and returns are shared. Therefore, a single problem will generate either only one diagnostic code or multiple codes.Power for the Ignition Transformer PrimarySome power circuits send signals to a single cylinder. A high side short circuit will affect only that cylinder.Some power circuits send signals to more than one cylinder. For this reason, a high side short circuit will affect more than one cylinder.Return for the Ignition Transformer PrimaryBoth the master ECM and the slave ECM have internal returns for the ignition transformers on the left side of the engine. Some of the returns consist of groups of terminals that are connected via diodes inside the master ECM. This means that a return short circuit to the +Battery will simultaneously affect all of the cylinders that are grouped.For the combinations of cylinders that can be affected by a condition, refer to Table 3.
