The electronic brake control module (EBCM) receives a serial data message from body control module (BCM) that the brake pedal is applied and to ensure that the states of their feedback circuits agree.
• | The ignition is ON. |
• | The vehicle speed is greater than 16 km/h (10 mph). |
• | The ignition voltage is greater than 9.5 volts. |
• | The brake pedal is sensed as applied for 6 minutes. |
• | The vehicle speed is greater than 21 km/h (13 mph). |
The ABS/TCS/VSES if equipped, remains functional.
• | The condition for the DTC is no longer present. |
• | The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles. |
