See PASS-Key® III+ Electronic Immobilizer Operation on page 3‑21 for more information. SERVICE TRACTION CONTROL If your vehicle has StabiliTrak, this message displays when there is a problem with the Traction Control System (TCS).

The tire pressure light also flashes and then remains on during the same ignition cycle. See Tire Pressure Light on page 4‑41. Several conditions may cause this message to appear. See Tire Pressure Monitor Operation on page 6‑84 for more information. If the warning comes on and stays on, there may be a problem with the TPMS. See your dealer. SERVICE TRAILER BRAKE SYSTEM On vehicles with the Integrated Trailer Brake Control (ITBC) system, this message displays and a chime may sound when there is a problem with the ITBC system. When this message displays, power is no longer available to the trailer brakes. As soon as it is safe to do so, carefully pull your vehicle over to the side of the road and turn the ignition off.
