U3003 Lincoln Code - ABS Module Battery Voltage
Quick Answer
The Anti-Lock Brake System (ABS) Module, hydraulic pump and solenoid valves require an operating voltage that is between 10 and 17 volts. Common causes include Faulty Anti-Lock Brake System (ABS) Module, Anti-Lock Brake System (ABS) Module harness is open or shorted, Anti-Lock Brake System (ABS) Module circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code U3003 Lincoln Description
Internally to the ABS module, the ignition voltage supply circuit is used as a redundant back up for the battery voltage supply circuit in case the battery voltage supply circuit is interrupted. If the battery voltage supply circuit is interrupted, the ABS module immediately shuts off and does not enter the power latch mode. The module uses the power latch mode to write certain parameters (such as learned offsets numbers) to non-volatile memory. At the beginning of each ignition cycle, a counter value is increased by 1 after a specified vehicle speed has been reached and a specified time has elapsed. When the ABS module enters the power latch mode, this counter is reset to 0.
What are the Possible Causes of the DTC U3003 Lincoln?
- Faulty Anti-Lock Brake System (ABS) Module
- Anti-Lock Brake System (ABS) Module harness is open or shorted
- Anti-Lock Brake System (ABS) Module circuit poor electrical connection
