C0110

DTC C0110





Circuit Description
The pump motor is an integral part of the BPMV, while the pump motor relay is integral to the EBCM. The pump motor relay is not engaged during normal system operation. When ABS or TCS operation is required the EBCM activates the pump motor relay and battery power is provided to the pump motor.

Conditions for Running the DTC
^ The ignition switch is in the ON position.
^ Initialization is complete.

Conditions for Setting the DTC
^ Pump motor voltage is not present 60 milliseconds after activation of the pump motor relay.
^ Pump motor voltage is present for more than 2.5 seconds with no activation of the pump motor relay.
^ Pump motor voltage is not present for 40 milliseconds after the pump motor relay is commanded off.

Action Taken When the DTC Sets
If equipped, the following actions occur:
^ A malfunction DTC stores.
^ The ABS/TCS disables.
^ The amber ABS/TCS indicator(s) turn on.
^ The Brake Warning indicator turns on.

Conditions for Clearing the DTC
^ The condition responsible for setting the DTC no longer exists and the scan tool Clear DTCs function is used.
^ 100 ignition cycles pass with no DTCs detected.

Important: After the DTC is cleared using ignition cycle default, the vehicle must be driven above 12 Km/h (8 mph) for the ABS/TCS indicator(s) to turn off.

Diagnostic Aids
It is very important that a thorough inspection of the wiring and connectors be performed. Failure to carefully and fully inspect wiring and connectors may result in misdiagnosis, causing part replacement with reappearance of the malfunction.
^ Thoroughly inspect any circuitry that may be causing the complaint for the following conditions:
- Backed out terminals
- Improper mating
- Broken locks
- Improperly formed or damaged terminals
- Poor terminal-to-wiring connections
- Physical damage to the wiring harness

^ The following conditions may cause an intermittent malfunction:
- A poor connection
- Rubbed-through wire insulation
- A broken wire inside the insulation

^ If an intermittent malfunction exists refer to Testing for Intermittent and Poor Connections.

Test Description
The number below refers to the step number on the diagnostic table.
3. Tests the pump motor circuits of the BPMV for a short to the housing of the BPMV. The wiring from the BPMV to the EBCM should not be repaired.
