Supersedes Technical Service Bulletin Group 48 number 13\-53 dated September 10, 2013. On vehicles equipped with a manual transmission, a steering warning may briefly display in the instrument cluster when the engine is restarted after improper use of the clutch pedal. For example, the warning may appear when the engine is restarted after the clutch pedal has been released too quickly during low\-RPM, low\-speed parking lot maneuvers. symptom codes may be stored in the diagnostic log under the power steering control module. The vehicle system voltage drops when the starter motor is operating. Because the power steering control module has a parallel circuit with the starter motor \(terminal 29\), this normal voltage drop may set a symptom code within the scenario described in the Condition section of this bulletin.
