PA - Testing Notes

NOTE: You should enter this Pinpoint Test only when checking computed timing, or you have been directed here from Quick Test.


REMEMBER


To prevent the replacement of good components, be aware that the following non-EEC areas may be at fault.

- Base engine

- Distributor

- TFI module


This Pinpoint Test is intended to diagnose only the following:


- Harness circuit: SPOUT

- Base timing

- Processor assembly


DESCRIPTION


The Spark Output (SPOUT) is a digital signal generated by the EEC-IV module which supplies desired spark timing and, in some instances dwell information to the module. Normally there will be one and only one SPOUT pulse for each PIP period.
