Code B482, Anti-Lock Pressure Problem: Notes

This code indicates that brake pressure switch has indicated a low pressure condition to BCM. If Code B482 is set and braking problems are experienced, diagnose ABS and normal braking system. Code B482 sets whenever circuit No. 933 is pulled low to ground and remains low for 50 seconds. As soon as circuit No. 933 goes low, the Red brake telltale will illuminate. The warning message on the Digital Instrument Cluster (DIC) for low brake pressure will not illuminate until after 50 seconds. The amber ANTI-LOCK telltale in the IPC is controlled only by ABS control unit.
