Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Operating Functions
In Jump Assist the APM converts the 12 volt DC to high voltage (HV) DC. The high voltage DC can then charge the hybrid drive motor batteries. During this mode of operation the APM and vehicle systems may draw up to 80 amps of current from the vehicles 12 volt DC system. An external 12 volt DC battery charger is required during the Jump Assist mode. In order to guarantee a successful engine start, approximately 20 percent state of charge (SOC) in the hybrid drive motor battery is recommended. Refer to Jump Assist . A successful Jump Assist can be expected to take an extended period of time not less than 20 minutes.
The APM hardware requires a minimum voltage level on the hybrid drive motor battery in order to initiate the Jump Assist function. If there is less than this required voltage level, the hybrid drive motor battery assembly must be replaced.
