This bulletin applies to 2010-2013 Cadillac SRX models. A no-start or other concern may be experienced after swapping an ECM or other modules from one vehicle to another.
This bulletin applies to 2012 Nissan Juke vehicles. When diagnosing for DTC C1130 (engine signal), ECM related DTCs must be diagnosed, repaired and DTCs erased first.
This bulletin applies to 2012-2014 Chevy Tahoe vehicles that exhibit unwanted grade braking, low power and/or a busy-shifting transmission. These issues may be caused by the BPP (brake pedal position) sensor not being learned correctly in the ECM.
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.
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.
This bulletin applies to 2013-2014 Buick Encore vehicles equipped with a 4-cylinder engine. The concern may involve an intermittent engine no-crank condition.
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.
This bulletin applies to 2005-2013 Honda Pilot vehicles. If you’ve cleaned or replaced the throttle body, and now you have a fluctuating idle, a MIL on with DTC P2279 (intake air system leak) and/or P0507 (idle control system rpm higher than expected), it’s likely that the throttle plate is now in a different position from the one the ECM/PCM had previously learned.
Some owners of 2007-2014 Cadillac Escalade vehicles may complain of an SES light on and a constant engine misfire. In some cases they may also note an engine tick/knock noise.
Honda ECM/PCM connectors are now embossed with geometric shape symbols to easily tell them apart. Connector A (white) has a square; connector B (gray) has a triangle; and connector C (green) has a circle.
