ABS Pump Motor Circuit Fault
The brake control system has detected a fault involving the ABS hydraulic pump motor or its electrical control circuit.
00 // CODE DEFINITION
What C0110 means
C0110 is used on some vehicles for an ABS pump motor or pump-motor circuit fault.
Exact code wording varies by manufacturer, so vehicle-specific service information should be checked before testing.
01 // COMMON SYMPTOMS
What you may notice
02 // COMMON CAUSES
What can trigger C0110?
ABS pump motor fault
The hydraulic-unit pump motor may be seized, open, or internally damaged.
Pump power-supply fault
A fuse, relay, high-current connection, or wiring problem may prevent pump operation.
Poor pump or module ground
High resistance in the ground path can prevent normal motor operation.
03 // DRIVEABILITY
Can I keep driving with C0110?
Use caution. A high-severity fault can affect engine, transmission, electrical, or emissions-system operation. If the vehicle is running poorly, overheating, losing oil pressure, flashing the check-engine light, or entering reduced-power mode, avoid continued driving until the cause is diagnosed.
04 // DIAGNOSTIC ORDER
Start here
Scan the ABS module
Review all brake-system codes and freeze-frame or enhanced data.
Command the pump if supported
Use a bidirectional scan-tool test to verify pump response.
Check power and ground
Verify the pump or hydraulic control unit receives proper voltage and ground under load.
Test the motor circuit
Inspect wiring, connectors, relays, and current path before replacing the hydraulic unit.
05 // COMMON REPAIR AREAS
Systems commonly involved
These are common areas associated with C0110. Testing should confirm the actual fault before parts are replaced.
ABS pump motor fault
The hydraulic-unit pump motor may be seized, open, or internally damaged.
Pump power-supply fault
A fuse, relay, high-current connection, or wiring problem may prevent pump operation.
Poor pump or module ground
High resistance in the ground path can prevent normal motor operation.
06 // DIAGNOSTIC PRINCIPLE
Confirm the fault before replacing parts
C0110 identifies a condition detected by the vehicle control system. It does not automatically identify one failed component. Test the affected system before replacing parts.
