Vehicle Speed Input

The BCM monitors the vehicle speed input to determine the total distance traveled in order to change the inadvertent battery rundown protection timer.

The BCM determines the distance traveled by interfacing with the vehicle speed CKT 389 which makes a ground transition 4000 times per 1.6 km (1 mile) traveled. Once the vehicle has been driven past the 15 mile (24 km) mark, the BCM changes inadvertent battery power rundown protection timer from 3 minutes to 10 minutes.

In addition, the BCM uses the vehicle speed CKT 389 for the operation of the turn signal reminder.

If the inadvertent battery power rundown protection stays at 3 minutes on vehicles with more than 15 miles (24 km), refer to Audible Warnings for possible malfunction of the turn signal reminder.
