C0110 00

Circuit/System Description

The pump motor is an integral part of the brake pressure modulator valve assembly, while the pump motor relay is integral to the electronic brake control module (EBCM). The pump motor relay is not engaged during normal system operation. When the ABS, traction control or stability control operation is required, the EBCM activates the pump motor relay and turns the pump motor ON.

Conditions for Running the DTC

Ignition ON.

Conditions for Setting the DTC

    •  A short to ground or an open/high resistance on the pump motor B+ circuit is detected for 0.1 s.
    •  An open/high resistance on the pump motor ground circuit is detected for 0.1 s.
    •  A faulty pump motor or pump motor relay is detected.

Action Taken When the DTC Sets

    •  The EBCM disables the ABS, traction control, and stability control for the duration of the ignition cycle.
    •  The ABS indicator turns ON.
    •  The traction control/stability control-active indicator turns ON.

Conditions for Clearing the DTC

    •  A current DTC clears when the diagnostic runs and passes.
    •  The EBCM will turn OFF the indicators and enable the system functions in the next ignition cycle after driving at a speed of greater than 15 km/h (9 MPH).

Circuit/System Verification

Ignition ON, command the ABS Pump Motor Increase and Decrease with the scan tool. The pump motor should turn ON and OFF.

Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the K17 Electronic Brake Control Module..
  2. Test for less than 5 Ω between the ground circuit terminal 13 and ground.
    3. ⇒ If greater than the specified value, test the ground circuit for an open/high resistance.
  3. Verify that a test lamp illuminates between the B+ circuit terminal 1 and ground.
    4. ⇒ If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
  4. If all circuits test normal, replace the brake pressure modulator valve assembly and verify the DTC does not reset.
    5. ⇒ If the DTC resets, replace the K17 Electronic Brake Control Module.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
