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.


Throttle Body Relearn

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.


Acura Nut Update

Just in case you’re working on a 2014 Acura MDX, pay attention to the wheel nut specs, as nut size and torque differ from those on the 2013 MDX.


Probably Just a Fuse

Some 2011 Ford Fiesta vehicles may exhibit a MIL on with DTC U029F set in the PCM and/or a no-crank condition, with no communication with the PCM.


Tension Reminder

This bulletin applies to all Subaru models equipped with 1.8, 2.0, 2.2 and 2.5L EJ engines with regard to automatic timing belt tensioners. These tensioners must be compressed very slowly, and with the rod in a vertical position. Compressing them too quickly, with too much applied force, or compressing with the rod in a horizontal position may result in weakening or tensioner damage.


Stubborn BMW

This bulletin applies to 2013 BMW 528i xDrive vehicles with the N55 engine and manual transmission and Continental high-pressure pump. The engine may not start on the first attempt when cold.


Ford GTDI Glitch

With some 2012-2013 Ford Edge vehicles built on or before 8/2/2012 and equipped with the 2.0L GTDI engine, technicians may find the MIL on with DTC P06B8.


Can’t Find Honda Plugs?

American Honda parts stock carries most engine oil and coolant gallery plugs (bolts and washers) separately, even though they might not be listed in the parts catalog. Following is a handy chart.


Lifty Not Nifty

This bulletin applies to 2007-2014 Cadillac Escalade and Escalade ESV vehicles. Some customers may state that the power liftgate is inoperative from all the switches and the keyless entry transmitter only with the ignition in the off position. If the ignition is in the accessory or the run position, the liftgate will operate correctly.


Ignore the DTC

This bulletin applies to 2011-2014 GM vehicles equipped with OnStar. While diagnosing a vehicle with an OnStar concern, technicians may find DTC B101D-37 in the OnStar module (VCIM) while checking for codes.
