Drive Away Release

With the vehicle static and the park brake applied, the drive away release mode releases the EPB when the accelerator pedal is pressed, without the EPB switch being set to the release position, to assist with a smooth drive away. This mode is only active if either the driver door is closed, or if the driver seatbelt is buckled and the engine is running.

The point at which the ABS control module releases the brakes is determined by the following factors:

• Tilt angle - from the longitudinal accelerometer sensor in the RCM
• Engine torque - from the ECM
• Accelerator pedal applied - from the APP sensor
• Clutch pedal releasing - from the clutch pedal position sensor (manual transmission vehicles)
• 1st or reverse gear selected - from the 1st and reverse gear switch (manual transmission vehicles)
• D (drive) or R (reverse) selected - from the TCM (automatic transmission vehicles)

The drive away release operation can be delayed by holding the EPB switch in the applied position, then releasing it back to its neutral position at the required time.
