Code P0BBD GMC Description
The hybrid battery assembly consists of 40 individual batteries. Each battery is rated at 7.2 volts. A pair of batteries is rated at 14.4 volts. The batteries are connected together in a series circuit. The BECM monitors the hybrid battery voltage on every two batteries for a total of 20 locations, across the battery assembly. The BECM monitors and compares these 20 voltage measurements, if the BECM detects a voltage difference greater than a calibrated value on any two consecutive hybrid battery voltage measurements this DTC will set.
