C0564:00, U3003:16

Refer to VEHICLE DYNAMIC SYSTEMS for schematic and connector information.

Normal Operation and Fault Conditions

The ABS module, hydraulic pump and solenoid valves require an operating voltage between 10 and 17 volts. The ABS module receives this voltage from the BJB. The ABS module has a single ground circuit located in the engine compartment wiring harness. The ABS module sets this DTC if there is excessive resistance or an open in one or more of these circuits, a discharged battery or an inoperative charging system.

The SOBDMC monitors fault messages from the ABS module. When the ABS module sets DTC U3003:16, the SOBDMC sets a DTC and illuminates the MIL.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Conditions
C0564:00	ABS Control Module System Voltage Low: Not Sub Type Information	The SOBDMC sets this DTC when the ABS module sets DTC U3003:16.
U3003:16	Battery Voltage: Circuit Voltage Below Threshold	This DTC sets in continuous memory and on-demand if the voltage supplied to the ABS module falls below 10 volts.

Visual Inspection and Diagnostic Pre-checks

Make sure the vehicle battery terminals and cables are free of any corrosion and other contaminants.
Make sure the vehicle battery terminals are tightened to their correct torque specifications.
Make sure BJB fuses 7 (40A), 8 (30A) and 19 (5A) are OK.
