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 you are experiencing braking problems, 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.
