Normal Operation

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.

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.

Possible Causes
- Fuse
- Circuit 176 (PK/LG) short to ground
- Circuit 3800 (LG/BK) open or short to ground
- Circuit 57 (BK) open
- Jump start switch
- HVTB
