DTC Descriptors

DTC C0299 00

- Brake Booster Performance

DTC C12FF 00

- EBCM Internal Malfunction

DTC C0299 31

- Brake Booster Performance General Checksum Failure

Circuit/System Description

The electronic brake control module (EBCM) uses input from the brake master cylinder piston position sensor and the brake switch to determine

when the brake pedal is being applied and with how much force. These inputs are used to determine the driver's braking intent which is used to the

control amount of pressure applied to the wheels.

Conditions for Running the DTC

* Ignition ON.

* The ignition voltage is greater than 10 volts.

Conditions for Setting the DTC

* The brake pedal is sensed as applied for 6 minutes.

* The vehicle speed is greater than 21 km/h (13 mph).

Action Taken When the DTC Sets

* The EBCM disables the antilock brake system (ABS), traction control and the vehicle stability enhancement system for the duration of the

ignition cycle.

* A driver information center message and/or a warning indicator may be displayed.

Conditions for Clearing the DTC

* The condition for the DTC is no longer present.

* The EBCM clears the history DTC when a current DTC is not detected in 40 consecutive drive cycles.
