For electric car owners, it can be frustrating when warning lights start flashing and fault codes appear. But don't worry, we're here to help you understand some common EV fault codes and how to resolve them. Having the right diagnostic tools can make a big difference, and that's why we'll also recommend some useful tools.
1. P0A80 - Replace Hybrid Battery
This fault code is common in hybrid vehicles and indicates that the battery is no longer functioning correctly. To rectify
this problem, checking each battery cell can help, but often the battery needs to be replaced entirely.
Recommended Tool
To accurately read and analyze fault codes in your hybrid or electric car, we recommend the ELM327 USB Diagnostic Cable with Switch – HS-CAN & MS-CAN – For FORScan. This tool will help you gain a deeper understanding of your car's condition.
2. BMS Fault Codes
BMS (Battery Management System) related fault codes can vary by manufacturer but typically signal problems with the battery's monitoring system. These issues can often be resolved with a system reset or a software update.
Recommended Tool
For BMW vehicles, the BMW Blue K DCAN USB Interface with Switch – K+DCAN USB Diagnostic Cable (FT232RL) can be a useful tool for reading and resetting BMS fault codes as well as other system codes.
3. TPMS-related Codes
While this sometimes pertains to more traditional vehicles, TPMS (Tire Pressure Monitoring System) is also important in electric cars. TPMS codes can often be resolved by checking and adjusting tire pressure and performing a relearn of the sensor positions.
Recommended Tool
Use the TPMS Relearn Tool + Tire Pressure Gauge (2-in-1) – TPA01 for GM Vehicles to easily perform these actions and ensure your vehicle is always in top condition.
