Code B482, Anti-Lock Brake Pressure Problem: Notes

This code indicates that the brake pressure switch has indicated a low pressure condition to the BCM. Code B482 sets whenever circuit No. 933 is pulled low to ground and stays low for 50 seconds. As soon as voltage goes low, the Red brake telltale will come on. The warning message on the DIC for "LOW BRAKE PRESSURE" will not come up until after 50 seconds, at the same time the code sets. The Amber anti-lock telltale in the IPC is controlled only by the ABS unit.

1. Determines if fault is present.
2. Determines if fault is due to circuit problem or actual ABS brake system problem.
