TRACTION CONTROL, 4WD, & AWD
Jeep - 1974-11
* PLEASE READ THIS FIRST *
Placing a non-compatible vehicle on a single-axle dynamometer could result in a safety hazard to technicians and damage to vehicle. Vehicles which use All-Wheel Drive (AWD) or traction control may not be clearly marked. Use common sense and take all necessary precautions when placing any vehicle on the dynamometer. Determine between full-time 4WD and All-Wheel Drive (AWD) for testing purposes. The following tables include information related to full-time 4WD and AWD vehicles, and how to disable the traction control system (if disengageable).
WARNING: DO NOT operate vehicle on a 2-wheel dynamometer if the DO NOT TEST column is marked.
