Code P1EE8 Chevrolet Description

The battery charger will diagnose its own systems and determine when a fault condition is present. Diagnostics and system status is communicated from the battery charger to the hybrid/EV powertrain control module 2 through serial data. The hybrid/EV powertrain control module 2 is the host controller for Diagnostic Trouble Code (DTC) information. This DTC is for the battery charger are internal measurements that verify the charger is performing properly. The battery charger measures internal voltages, currents, and temperatures and verifies they are within the proper range.
