48 A S P D e c e m b e r 2 018 T e c h n i c a l S e r v i c e B u l l e t i n s ACURA ACURA DRAIN RELOCATED This bulletin applies to 2009 and later Acura TL and all V6 Acura models. e engine block design was changed to relocate the engine valley drain hole. In the previous design, collected fluid in the valley would run out through a drain hole in the rear of the block and potentially into the torque converter or clutch housing. In the new design, it runs out through the same valley drain hole, but now bypasses the housing entirely and exits through a new drain hole on the right rear side of the block behind the rear engine mount. Keep this in mind if you're troubleshooting an engine for an oil or coolant leak. Instead of replacing the block, verify the leak source. Visible water staining around the lower drain hole could simply be runoff from engine cleaning. HONDA HONDA VAS TROUBLESHOOTING This bulletin applies to 2008-2012 Honda Accord and 2010-2011 Crosstour vehicles. If you're troubleshooting a vehicle with a DTC U0122 (F-CAN malfunction...ECM/PCM to VSA modulator control unit), no HDS communication with the VSA, and/or various VSA system indica- tors are on (ABS, BRAKE or VSA), the two-pin connector C201 (behind the right front bumper) could be the culprit. If it's been damaged or the connector halves are not completely snapped together, you could wind up with these symptoms. is can easily occur if the vehicle has been serviced in a body shop repair near the connector. e constant 12 volts being supplied through the C201 connector from the underhood fuse/relay box to the fail-safe relay (FSR +B) in the VSA mod- ulator control unit may be cut. Without that volt- age, the unit won't turn on. Before wasting time by extensive troubleshooting, check connector C201 and make sure it's not so-set or damaged. The newer block design allows fluid collected in the valley to exit the right rear side of the block behind the engine mount. The C201 two-pin connector is located on the right side behind the front bumper. HYUNDAI HYUNDAI PCM This bulletin applies to 2010-2013 Hyundai Elantra, Genesis, Sante Fe, Sonata and Tucson models where DTC P0605 is set and an internal control module read-only (ROM) error is found. Inspect the following: Engine coolant temperature sensor (and related wiring). MAP sensor and turbocharger boost sensor (MAP sen- sor #2 for turbo). Exhaust system modifications. When P0605 and P2105 are the only two DTCs present, replace the PCM. If a PCM is replaced and a warranty claim is submitted, attach the DTC printout and carefully document the conditions.
