Ignition Timing Connector: Description and Operation

Spout/SAW Connector:

DESCRIPTION
The Spark Angle Word (SAW),or Spark Output (SPOUT) connector is used to open and close the circuit between the Powertrain Control Module (PCM)and the Ignition Control Module (ICM) for checking base timing.

OPERATION
When the SPOUT or SAW connector is inserted in the harness connector, the ICM operates according to PCM timing data (computed timing). When the SPOUT or SAW connector is removed from the harness connector, the ICM operates on the Profile Ignition Pickup (PIP) signal only (base timing).
