Anti-Lock Brake System

There are two Anti-Lock Brake Systems (ABS) used in this vehicle. One is the standard system and the other is equipped with traction control.

Power for the Anti-Lock Brake System (ABS) is supplied by three fuses. There is a 10 Amp fuse in cavity 6 of the junction block. Power for the fuse is supplied by circuit A22. This circuit is HOT in the RUN position only.

Power for the A22 circuit is supplied on circuit A2 from the Power Distribution Center (PDC). The A22 circuit is protected by a 40 Amp fuse located in cavity J of the PDC.

Circuit F20 connects, from the fuse in cavity 6 of the junction block, to the ABS control module and the coil side of the ABS main relay

The second fuse is located in the PDC cavity C. This fuse powers the contact side of the ABS pump motor relay on circuit A1O. This relay is located on the side of the PDC and the fuse is HOT at all times. The third fuse is also located in the PDC. This fuse is located in cavity I and is used to power the contact side of the ABS main relay This fuse is HOT at all times.

There are three grounding points used for the ABS control module. A11 three of the grounds are on circuit Z1 from the control module to the left front frame rail.
