What does EPBL-A303 mean?
Tesla alert code in the Electronic Parking Brake Left (EPBL) module. When EPB was applying the current measured went above the max no load current before piston position estimate predicted it would. The Electronic Parking Brake and Electronic Parking Brake Monitor took longer than expected to save caliper state in non-volatile memory. Caliper state saved to Electronic Parking Brake and Electronic Parking Brake Monitor mismatched for more than 500ms Electronic Parking Brake and Electronic Parking Brake Monitor states match Non-volatile memory error due to Electronic Parking Brake and Electronic Parking Brake Monitor mismatch One or more of the expected CAN messages from PTC were not received.
