Ignition Module: Notes

Distributor utilizes an ignition module, mechanical and vacuum advance mechanism. Ignition module receives a Profile Ignition Pulse (PIP) signal from a pick-up coil located inside the distributor. The module also receives the spark output (SPOUT) signal from the ECA. The ignition spark timing is corrected according to the PIP and SPOUT signals. The corrected ignition diagnostic monitor signal is sent to the coil and ECA.
