comp driving mode retro fit?
Once AH is installed, then you have the choice of three modes ...
All On (default at engine start) ... both Traction Control (TC) and AH are ON
All Off - push the button once and both TC and AH are OFF
Competition Mode (Hold button for 5 seconds) AH is ON and TC is OFF.
Now, to install AH, you'd need to install the accelerometer and yaw sensor in the cabin, plus wiring to power them and allow them to communicate with the EBCM (though the wiring harness may already have the wires in place). The EBCM would need to be upgraded (yours is probably part #09367071, and I believe you need 09376711), and the BPMV would also need to be upgraded. I'm not sure if the BCM would need to be changed or re-programmed too. You'd also need to install the steering wheel angle sensor (and possibly wiring), and I'm not sure without a wiring diagream if any relays and/or fuses need to be added to make this work.
The parts alone would probably run in the neighborhood of $1,500.00

The ABS and TC systems use the wheel speed sensors to look for wheels that are locking or are over accelerating. The AH system uses the steering wheel position sensor along with the yaw sensor and accelerometer to determine over/understeer. All of that I understand.
Bill's comment intrigued me as it implies that the ABS is more sophisticated than I had thought.

You would need to gather a lot of parts like wheel speed sensors, tranny wire harness (speed sensor wiring on tranny harness), other sensors and re-program PCM.
Take a look at the connector to your EBCM ... going into the connector there should be the following wires in a row ...
Pin2 TAN/BLACK
Pin3 LIGHT GREEN
Pin4 Not Used
Pin 5 LIGHT GREEN/BLACK
Pin 6 LIGHT BLUE
Pin 7 Not Used
The key is Pin 5 ... if there is no wire there then the wiring harness does not support AH
Another place to look on the connector ...
Pin 16 Not Used
Pin 17 BLACK
Pin 18 LIGHT BLUE
Pin 19 DARK BLUE
Pin 20 Not used
Pins 17 and 19 are the keys here ... no wires and this will be a tough project.
