PA2 - Check Spout Circuit Continuity
Ignition Control Module (ICM) Connector:
- Key "OFF".
- Breakout box installed, Powertrain Control Module (PCM) disconnected.
- Disconnect Ignition Control Module (ICM).
- Measure resistance between test pin 36 at the breakout box and Spark Output (SPOUT) circuit at the ICM vehicle harness connector.
- Is resistance less than 5.0 ohms?
Yes -- Go to PA3. PA3 - Check Spout Circuit For Short to B+ (Excluding VREF)
No -- Service open circuit. Remove breakout box. Reconnect all components. Check timing.
