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 and has a single ground circuit. An overcharging condition in the charging system results in the ABS module setting a DTC. This DTC may also set in the ABS module due to battery charging or vehicle jump starting events.
DTC Fault Trigger Conditions
DTC | Description | Fault Trigger Conditions |
|---|---|---|
U3003:17 Battery Voltage: Circuit Voltage Above Threshold | This DTC sets in continuous memory and on-demand if the voltage supplied to the ABS module is above 17 volts. |
