Pinpoint Test E : U3003:17 - Abs (Anti-Lock Brake System) Module: Notes
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 2 ground circuits that splice together and terminate at a single location. 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 on-demand if the voltage supplied to the ABS module is above 17 volts. |
Possible Causes
