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.
• | Ignition ON. |
• | Ignition voltage is greater than 10 volts. |
• | Internal pressure sensor fault. |
• | Brake Signal does not correlate to Pressure Signal. |
• | Signal is erratic and changes faster than physically allowed. |
• | The EBCM disables the ABS/traction control system (TCS)/vehicle stability enhancement system (VSES) for the duration of the ignition cycle. |
• | A DIC message and/or a warning indicator may be displayed. |
• | The condition for the DTC is no longer present. |
• | The EBCM clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles. |
