Code P0ABD GMC Description
The Battery Energy Control Module monitors the voltage of the 32 battery cell groups. A voltage sense circuit is attached to each individual cell group. Each of these circuits terminate at a connector located on the top surface of the battery section. A serviceable auxiliary battery wiring harness connectors the voltage sense circuits to the Battery Energy Control Module, located directly above the Hybrid/EV Battery Pack. The Battery Energy Control Module also monitors the Hybrid/EV Battery Pack voltage in it's entirety. The Battery Energy Control Module compares the voltage of the entire pack to that of the sum of the voltages measures at each cell.
Diagnostics and system status are communicated from the Battery Energy Control Module to Hybrid Powertrain Control Module through serial data.
What are the Possible Causes of the DTC P0ABD GMC?
- Faulty Battery Energy Control Module
- Battery Energy Control Module harness is open or shorted
- Battery Energy Control Module circuit poor electrical connection
