Traction Control


PURPOSE
Traction Control is a function of the Powertrain Control Module (PCM) and the Electronic Brake and Traction Control Module (EBTCM) that reduces front wheel slip during acceleration by applying the front brakes and reducing engine power.



OPERATION
Communication between the PCM and the EBTCM is between the CKT 800 serial data line. The EBTCM may decide to apply the front brakes only or apply the front brakes and request reduced torque output from the powertrain. If the EBTCM requests reduced torque, the PCM may also disable between one and seven fuel injectors to achieve this.


DIAGNOSTIC NOTES

The disabled fuel injectors will be re-enabled one by one as the need for traction control ends.

Several diagnostic codes may disable Traction Control when set.
