Any fault/error (or damage to the vehicle) that will affect drivability or vehicle performance "can" cause reduced power. Consequently, the codes that have caused the traction control warning light to illuminate should first be downloaded and if those codes implicate any of the possible causes of reduced power, those codes should be fully resolved first. Once that step is accomplished, that is once the traction system is EITHER ruled out, or once repairs are made if there was damage due to the collision, if the reduced power issue remains, such would be resolved in a Reduced Engine Power Warning Light Diagnostic. The bottom line is, you can just simply request a reduced power diagnostic but, as noted, the mechanic will first consider the possibility that the underlying cause is a traction system fault. If the cause of reduced power is not found "there", it then becomes a reduced power diagnostic.
