Diagnostic Fault Information
Circuit/System Description
The pump motor is a bi-directional motor and is an internal part of the brake pressure modulator valve assembly. There are three solid state relays
in the electronic brake control module (EBCM) that operate the pump. The pump motor runs every few brake stops in order to fill the high pressure
accumulator with brake fluid anytime the engine is running.
Conditions for Running the DTC
* Ignition ON.
* Ignition voltage is greater than 10 volts.
* The system enable relay is ON.
* The pump motor has been commanded ON, OFF and ON again.
Conditions for Setting the DTC
* The EBCM detects a short to ground or an open/high resistance on the B+ circuit.
* The EBCM detects an open/high resistance on the ground circuit.
* The EBCM detects the pump motor runs continuously.
* The EBCM detects the pump motor is binding or stalled.
Action Taken When the DTC Sets
* The EBCM disables the ABS/Traction Control System/Vehicle Stability Enhancement System for the duration of the ignition cycle.
* The ABS indicator illuminates.
* The red Brake indicator illuminates.
