Flag 27: Quick Quad-Driver Output Fault

Flag will set if there is an open or short on any of the QDM output circuits. Fault must last at least 5 seconds. If any PCM codes have been set, diagnose, repair and clear codes before considering Flag 27 a problem. If only Flag 27 is set, this indicates an intermittent problem.
