Issue: Battery Energy Control Module (BECM) records DTC: P0A95-00 High Voltage Fuse 'A'
Causes: High Voltage (HV) auxiliary components failing with a short circuit, blowing fuses in the High
Voltage Junction Box (HVJB) and blowing the auxiliary fuse in the Battery Energy Module (BEM) - in
some cases other components are also damaged on the HV auxiliary circuit.
Action:
If Battery Energy Control Module (BECM) records DTC P0A95-00 High Voltage Fuse 'A', do not attempt
part replacements and extended diagnostics.
Submit a Technical Assistance (TA) to your Local Technical Support (LTS) who will provide diagnostic
guidance including procedures to test components on the HV auxiliary circuit.
Customers may report symptoms resulting from faults in the following areas:
Electric Air Conditioning (A/C) compressor – see note
Wired on-board charging module (BCCM)
Direct Current to Direct Current (DC/DC) converter
High Voltage (HV) interior heater
High Voltage Junction Box (HVJB)
BEM auxiliary fuse and BEM auxiliary contactor
Note: If advised as faulty, the Electric Air Conditioning (A/C) compressor must be replaced with a quality
assured part which is identified from serial number: 000857 02 9 68 (The make up of the serial number is:
First 6 digits (000857): unique sequential serial number, next 2 digits (02): Month of production, next digit
(9): Year of production, Last 2 digit (68): Electric Compressor).
Please see example of a typical electric compressor, the serial number on the “Compressor_label.pdf” is
S/N 02247107868.
Note: A Pathfinder and Topix Guided Diagnostic test is being developed to test the HV auxiliary circuit and
will be available in March 2019.
