Code P0CC3 GMC Description
The Starter/Generator Control Module uses the exponentially weighted moving average to calculate temperature fluctuations in the starter/generator cooling system. In addition, this diagnostic compares the temperature rate of change by a slope calculation within a set time when the Starter/Generator Control Module coolant pump turns ON. This diagnostic runs once after pump turns ON. If the temperature changes over time too quickly, the Starter/Generator Control Module will indicate a fault.
