Jump Starting

When it is required to jump start the vehicle, just like battery charging, it is important to connect the cables properly for the battery monitoring sensor to measure the energy input to the system to keep an accurate State of Charge. Connect the positive connection to the battery positive post, and connect the Jump Start negative to the vehicle ground. Do not connect to the battery monitoring sensor. Connecting directly to the battery negative post bypasses the ability of the vehicle to measure the input current with the battery monitoring sensor, and does not adjust the battery state of charge accordingly. For a convenient ground location look for the body ground cable coming off the clamp or the Battery Monitoring Sensor and connect in this location (typically on the shock tower sheet metal). The Electrical Energy Management recalculates the battery state of charge after 4 to 6 hours if the jump start negative cable is improperly installed.

NOTE: If the charger is incorrectly connected to the battery negative terminal, DO NOT reset the battery monitoring sensor using the diagnostic scan tool. This reset is reserved for new battery installation. This reset clears the learned battery data, the battery time in service, and affects the aging parameters, which have been learned since the installation of the battery.

If the battery was jump started by connecting to the battery monitoring sensor, force an internal reset by removing the battery monitoring sensor from the battery negative post or disconnecting the battery monitoring sensor connector and reconnecting.
