Test C: Anti-Lock (ABS) Hydraulic Pump Motor Circuit Failure

Test C: Anti-Lock (ABS) Hydraulic Pump Motor Circuit Failure
Refer to Vehicle/Diagrams, Vehicle Dynamic Systems for schematic and connector information.

Normal Operation
The operating voltage required to supply the ABS module, hydraulic pump and isolation valves is in a range between 10 and 16 volts.

Voltage is supplied by the battery junction box (BJB) through circuit 30-CF13 (RD) (hot at all times), circuit 30-CF6 (RD) (hot at all times) and circuit 15-CF6 (GN/YE) (hot in run). Ground is provided through circuit 31-CF6 (BK).

Possible Causes
^ Fuse
^ Circuit open
^ ABS module
