The fault code P1E03 indicates an issue with the hybrid battery pack cooling system. The estimated repair time for this fault code is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for most shops to charge between $75 and $150 per hour.

Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the location of the repair shop.

The P1E03 code indicates a high voltage in the HybridElectric Vehicle Battery 95 Circuit. The battery pack contains 288 cells grouped in parallel and series. The battery energy control module monitors the voltage of the 96 battery cell groups through the four hybridEV battery interface control modules.

The battery energy control module communicates diagnostics and system status to the hybridEV powertrain control module 2 through serial data.

The hybridEV powertrain control module 2 is the host controller for diagnostic trouble code information.
