2019+ Edge Advancetrac Sport Mode

[STBEAST]

I saw a video showing how when you 'double tap' the ESC button on a 2019-2024 Edge ST (and possibly even the other models), it puts the Advancetrac into Sport Mode.

A totally separate feature than pushing the sport mode (S button) on the rotary shift dial. There is not much information on this feature (none in the owner's manual), but it seems to have a notable effect on engaging the AWD, making it much more active. 

I monitored the AWD screen while trying out this 'hidden' mode and could see a difference throughout the driving range. It seems this mode would be very beneficial during inclement weather and off pavement. I have played with it quite a bit and I believe many Edge St owners don't even know it Exists. It may have been mentioned in previous topics, but sometimes searching for a topic on this forum can be a challenge.

Hope some of you get to read this valuable info. and wonder if this feature applies to the 2.0 Edge 2019+.

Happy Easter egg!

From the WSM:

 

Traction Control

The ABS module continuously monitors and compares the rotational speed of the drive wheels in relation to the non-driven wheels. When the
drive wheels begin to spin faster than the non-driven wheels, the ABS module modulates brake pressure to the appropriate brake caliper(s) by
opening and closing the appropriate solenoid valves inside the HCU while the hydraulic pump motor is activated. At the same time, the ABS
module calculates how much engine torque reduction is required to eliminate the wheel slip and sends this torque reduction message along with a
traction event message to the GWM over the HS-CAN2. The GWM sends the engine torque reduction message to the PCM over the HS-CAN1
and the traction event message to the IPC over the HS-CAN3. When the PCM receives the torque reduction message, it adjusts engine timing
and decreases fuel injector pulses to reduce the engine torque to the requested level. When the IPC receives the traction event message it flashes
the stability-traction control indicator (sliding car icon). Once the driven wheel speed returns to the desired speed, the ABS module returns the
solenoid valves in the HCU to their normal position, deactivates the hydraulic pump motor and stops sending the traction event and torque
reduction messages. The PCM returns engine timing and fuel injectors to normal operation and the IPC extinguishes the stability-traction control
indicator (sliding car icon). After the vehicle speed exceeds 100 km/h (62 mph), traction control is accomplished only through the PCM torque
control.

Traction control can be disabled using the traction control switch in the following manner:

 

• Momentarily pressing the switch disables only traction control, ABS, ESC and RSC remain enabled.
• Pressing the switch twice rapidly engages Sport Mode. Sport mode modifies the stability control intervention thresholds to allow for a more driving experience.
• Pressing the switch once after the system is deactivated fully enables the traction control system.
• Pressing the switch once after Sport mode is activated, deactivates Sport mode and fully enables the traction control system.

When the driver disables traction control, the IPC communicates traction control status to the GWM along the HS-CAN2. The GWM sends the

message to the ABS module along the HS-CAN2. The ABS module takes no further action in regards to traction control until the driver activates

the function or until the ignition is cycled from OFF to ON.

Thanks for that information.

But I do notice the AWD system (via the AWD screen) being much more active when in this mode. It becomes less front wheel drive biased when in sport mode and activates the AWD at a much lower threshold. Any explanation of this would be helpful.

It's in the software -- "all-wheel-drive calibration for balanced front and rear torque distribution" -- as shared in your January 2024 discussion on this same topic...

 

 

 

Good luck!
