Failure Effects Mode Management (Fail Safe Operation)

During some DIS faults, the FMEM portion of the DIS module will maintain vehicle operation. If the ignition module does not receive the SPOUT input signal, it will turn the coils on and off using the PIP signal. In doing so, the timing and dwell are fixed at 10 degrees BTDC. If the module does not receive the CID input signal, random coil synchronization will be attempted. Several start attempts may be required before the engine will start.
