Circuit Description

The pump motor is contained within the brake pressure modulator valve (BPMV). The pump motor ground is supplied though terminal D of the electronic brake control module (EBCM).

Conditions for Setting the DTC

DTC C0017 can only be set with the key in the ON position, the pump motor OFF, and the EBCM detected a short to ground on the pump motor circuit.

Action Taken When the DTC Sets
    • The solenoid relay opens, removing power from the pump motor and solenoids.
    • DTC C0017 is stored.
    • The antilock brake system (ABS) is disabled, ABS warning lamp is turned ON.

Conditions for Clearing the DTC
    • If the conditions that set DTC C0017 are no longer present, the DTC may be cleared by using the proper scan tool.
    • The DTC that has not occurred in 100 drive cycles will be cleared from history data.

Diagnostic Aids

Typical causes of DTC C0017:

    • Faulty BPMV
    • Faulty EBCM

Step

1

Did you perform the Diagnostic System Check-ABS?

Go to Step 2

Go to Diagnostic System Check - ABS

2
  1. Turn the ignition switch OFF.
  2. Disconnect the electronic brake control module (EBCM) harness from the EBCM.
  3. Remove the EBCM from the brake pressure modulator valve (BPMV).
  4. Inspect the EBCM to BPMV connector for conditions such as damage, corrosion, poor terminal contact, or the presence of brake fluid.

Were the terminals and connector OK, and the cavity free of brake fluid, damage and corrosion?

Go to Step 4

Go to Step 3

3
  1. If damage and/or corrosion is present, replace the EBCM and/or the BPMV as necessary.
  2. If the brake fluid is present, replace both the EBCM and the BPMV.

Did you complete the replacement?

System OK

4
  1. Connect an ohmmeter to terminal 1 of the BPMV and then to body ground. Note the resistance value.
  2. Connect an ohmmeter to terminal 2 of the BPMV and then to body ground. Note the resistance value.

Were both readings OL, open circuit?
