PB2 - Check Spout Circuit Continuity

Ignition Control Module (ICM) Connector:

- Key "OFF".

- Breakout box installed, Powertrain Control Module (PCM) disconnected.

- Disconnect Ignition Control Module (ICM) (Pins 1-6).

- 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 PB3. PB3 - Check Spout For Short to B+ (Excluding VREF)

No -- Service open circuit. Remove breakout box. Reconnect all components. Check timing.
