False DTC

This bulletin applies to the 2011 Subaru Forester equipped with a 2.5L naturally aspirated engine. DTC P0108 may be stored (manifold absolute pressure/barometric pressure circuit high input). There is a possibility that this DTC can be erroneously stored in memory when the starter motor is stopped before the engine starts completely.

Funky Idle

This bulletin applies to 2012 Acura RDX models. If the throttle body was recently cleaned or replaced, DTC P2279 (intake air system leak) or P0507 (idle control system rpm higher than expected) and a fluctuating idle exists, it’s likely that the throttle plate is now in a different position from the one that the PCM/ECM had previously learned. To fix the problem, the ECM/PCM must be relearned to the new throttle plate position.

History Mistake

This bulletin applies to 2010-2013 Chevy Equinox. A technician may note history DTCs stored immediately after vehicle service if the ECM wakes up (activates) while a 5-volt reference sensor is unplugged and the ignition is off. This may occur on any 2010-2013 vehicle that requires the GDS2 scan tool to establish vehicle communication.
