How do I fix code P0BBDCheck the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
Cost of diagnosing the P0BBD code
Labor: 1.0The cost of diagnosing the P0BBD code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
- Engine Light ON (or Service Engine Soon Warning Light)
P0BBD MeaningThe Drive Motor Generator Battery Control Module is also referred to as the Battery Energy Control Module (BECM). The BECM will diagnose its own systems and determine when a fault condition is present. Diagnostics and system status is communicated from the BECM to the Hybrid Powertrain Control Module (HPCM) through the Hybrid LAN communication circuit. The HPCM is the host controller for Diagnostic Trouble Code (DTC) information.
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.
