PINPOINT TEST 4: DTC P0A95 - HIGH-VOLTAGE FUSE - HYBRID
Normal Operation
The high-voltage traction battery (HVTB) fuse is part of the service disconnect plug. The battery control module (BCM) monitors the HVTB fuse status at all times to determine if an open is present.
- DTC P0A95 High-Voltage Fuse - The BCM cannot detect the difference between a failed fuse or if the service disconnect unplugged. Either condition causes the BCM to set this DTC.
Possible Causes
- High-voltage fuse
- Service disconnect plug
- HVTB
Diagnostic Procedure
WARNING:Wear high-voltage insulated safety gloves and a face shield when working with high-voltage batteries or cables. The high-voltage insulated safety gloves should be of the appropriate safety and protection rating. Inspect the gloves before use and always wear them with the leather outer glove. Any hole in the rubber insulating glove is a potential entry point for high-voltage. Failure to follow these instructions may result in serious personal injury or death.
WARNING:Turn OFF the ignition switch for a minimum of 5 minutes before removing high-voltage cables. High-voltage cables and wiring are orange in color. The nominal high-voltage traction battery voltage (HVTB) is 330 V DC. Failure to follow these instructions may result in serious personal injury or death.
WARNING:Depower the high-voltage traction battery (HVTB) before carrying out any removal or installation procedures affecting the high-voltage battery system. Failure to follow this instruction may result in serious personal injury or death.
WARNING:When servicing the high-voltage system, establish a buffer zone per the specified procedure. Failure to follow this instruction may result in serious personal injury or death.
NOTE:Before installing a new service disconnect plug, first verify that the plug is installed correctly and in the lock position.
NOTE:In case of a failed high-voltage fuse, do not insert a new service disconnect plug until it is confirmed that there is no problem in the HVTB battery system.
