DIAGNOSTIC AIDS
This code is primarily for information only. As an aid to the technician, this code indicates that there are no problems in the ABS/TCS system, if it is a history code. If it is a current code, the PCM has detected a malfunction within the engine control system that would not allow traction control to function, or there may be a suspect PCM. Refer to Powertrain Control Module Diagnosis in Powertrain Management 3.5 for information on PCM diagnosis.
