DTC C0131 00: ABS Pressure Circuit No Additional Information
Circuit/System Description
The electronic brake control module (EBCM) uses input from the brake pressure sensor for more accurate control during a vehicle stability enhancement system (VSES) event.
Conditions for Running the DTC
| • | Ignition voltage is greater than 8 volts. |
Conditions for Setting the DTC
| • | Brake signal does not correlate to pressure signal. |
| • | Signal is erratic and changes faster than physically allowed. |
Action Taken When the DTC Sets
| • | The antilock brake system (ABS) indicator turns ON. |
| • | The vehicle dynamics caution (VDC) indicator turns ON. |
| • | The driver information center (DIC) displays the SERVICE STABILITRAK message. |
Conditions for Clearing the MIL/DTC
| • | The condition for setting the DTC is no longer present. |
| • | The ABS indicator may remain illuminated after repairs are made and DTCs are cleared, until the vehicle is operated at speeds greater than 13 km/h (8 mph) and the self test is completed. |
| • | The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles. |
