Diagnostic Aids
WARNING: This page is about a different car, the 2002 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
Condition could be caused by a short between circuits 2135 and 2136. A malfunctioning shorting bar could also cause this condition. With scan tool hooked up and turned on, wiggle suspect wires and watch scan tool display for current DTC to appear or disappear, indicating source of intermittent condition.
