C0235

C0235 or C035

Circuit Description
The EBCM receives the rear wheel speed signal from the VCM/PCM. The signal from the VCM/PCM is always high (12 volts) when the ignition is ON and the vehicle is not moving.

Conditions for Running the DTC
^ The ignition is ON.
^ The vehicle is not moving.

Conditions for Setting the DTC
The voltage on the vehicle speed signal circuit is detected as being low for more than 500 milliseconds.

Action Taken When the DTC Sets
^ The ABS and BRAKE indicators are commanded on.
^ The ABS is disabled for as long as the malfunction is present.

Conditions for Clearing the DTC
^ Repair the condition(s) responsible for setting the DTC.
^ Use the scan tool in order to clear the DTC.

Diagnostic Aids
Thoroughly inspect connections or circuitry that may cause an intermittent malfunction. Inspect for the following:
^ Backed out terminals
^ Improper mating
^ Broken locks
^ Corrosion
^ Improperly formed or damaged terminals
^ Poor terminal-to-wiring connections
^ Physically damaged wiring
^ Wiring broken inside the insulation

Test Description

The number below refers to the step number on the diagnostic table.
3. This step tests if the VCM/PCM is sending a 12 VDC signal to the EBCM.
