Pontiac Problems? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner till early morning.
What is the battery voltage while running with this warning light on?
Can you tell me what the voltage on the battery is without the light on?
Once it stalls will it restart easily?
How often is this occurring?
The BCM is storing this code because there is a module on the data communication circuit that itself or its wiring is shirted to power or ground causing the engine to stall. We need a diagnostic tool to see which modules are losing communication and storing U codes.
