PINPOINT TEST 10: DTC B1016 - JUMP START CONTROL MODULE FAULT - HYBRID

Normal Operation

When the jump start button is momentarily pressed, the jump start control module within the high-voltage traction battery (HVTB) uses the low-voltage battery during a 10-minute process (8-minute charge plus 2 minutes rest) to step up the low-voltage in an effort to charge the high-voltage battery to the point where it may start the engine. With the high-voltage battery state of charge at 30%, the vehicle can be driven.

- DTC B1016 (Jump Start Control Module Fault) - A jump start control module Controller Area Network (CAN) communication failure causes the traction battery control module (TBCM) to set this DTC.


NOTE: If the jump start switch is pressed and held for longer than 6 seconds, the jump start process aborts. The LED flashes for approximately 2 minutes before another jump start can be attempted. The jump start switch needs to be pressed only momentarily.

Possible Causes
- Fuse
- Wiring, terminals or connectors
- Jump start switch
- 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.
