Code P1FF0 Description
The battery energy control module monitors the voltage of the 96 battery cell groups. The voltage sense lines are attached to each individual cell group, and these sense lines terminate at a connector located on the top surface of the battery section. A voltage sense harness joins this connector to the battery energy control module.
The battery energy control module contains internal interface control modules that monitor specific cell groups.
The battery energy control module will determine when a fault condition is present. Diagnostics and system status are communicated from the battery energy control module to the hybrid powertrain control module 2 through serial data. The hybrid powertrain control module 2 is the host controller for diagnostic trouble code information.
What are the Possible Causes of the DTC P1FF0?
- Faulty Hybrid/EV Battery Interface Control Module
- Hybrid/EV Battery Interface Control Module harness is open or shorted
- Hybrid/EV Battery Interface Control Module circuit poor electrical connection
How to Fix the DTC P1FF0?
