Diagnostic Aids: C0298

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2004 Oldsmobile Bravada, 2004 GMC Envoy XUV, 2004 GMC Envoy XL, 2004 GMC Envoy, and 2004 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.

A requested torque signal malfunction is only one possible cause for the PCM to lose the ability to perform traction control. DTC C0298 may set due to engine overheating, throttle actuator control failure, loss of ignition timing control by the PCM, etc. If DTC P0856 has not set, refer to Diagnostic System Check - Engine Controls in Engine Controls - 4.8L, 5.3L and 6.0L in order to identify other possible causes of DTC C0298.
