Display group 022
Notes:
Display group 022 should only be considered on vehicles with traction control (ATC).
Vehicles with traction control (ATC) can be recognized by the ATC indicator light in the instrument cluster and/or ABS (ATC)
On Board Diagnostic (OBD).
Repair Manual, Brake System On Board Diagnostic (OBD), Repair Group 01.

The wheel slip information for traction control (ATC) is calculated in the ABS control module. If slip is recognized, the ABS
control module requests a reduction in torque from the Engine Control Module (ECM). This torque reduction is divided into 12
reducing stages.
With a cold engine, coolant temperature less than 20 C (68 F), the reduction of engine torque is obtained:
With retarded ignition timing angle for lower reducing stages (1-5)
By brief shut-off of individual fuel injectors for higher reducing stages (6-12)
If the engine is warm, coolant temperature greater than 40 C (104 F), the engine torque reduction is obtained only by briefly
switching off individual fuel injectors.
