combination lamp, daytime running lamp (DRL), or fog lamp. This TSB illustrates the various causes of condensation inside the lamp assembly. Lamp assembly replacement is NOT necessary in most cases. This condition can be eliminated by turning on the lamps with the engine running for several minutes or during normal driving operation.

This TSB provides a procedure to test each clutch in the transmission. If the vehicle fails the stall test, replace the transmission. PASS: Stall speed is between 1700~2900 rpm (See shop manual for stall speed). FAIL: Engine revs to redline limit (6,000~6,500 rpm). If so, replace the transmission.

This procedure is necessary to reduce the TCU learning time and improve the shift quality. Before replacing an automatic transmission: Input the data into the TCU using the GDS. Before replacing a TCU: Back up the oil pressure data from the old TCU into the GDS and then transfer the data to the new TCM.

This procedure is necessary to reduce the TCU learning time and improve the shift quality. Before replacing an automatic transmission (Pages 2~3): Input the data from the new transmission into the TCU using the GDS. Before replacing a TCU (Pages 4~6): Back up the oil pressure data from the old TCU into the GDS and then transfer the data to the new TCM.

drivers-side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN). These inflators were not supplied, approved, or authorized by the vehicle manufacturers and have primarily been found in vehicles that previously experienced a crash and underwent airbag replacement using non-genuine parts. These dangerous inflators have ruptured during deployment, posing a serious risk of injury or death due to metal fragments entering the vehicle cabin. To date, Hyundai is aware of three people who have died while driving a Hyundai vehicle with one of these substandard replacement airbag inflators that deployed in what likely would have been a survivable crash. NHTSA has issued a public advisory urging vehicle owners and service professionals to have vehicles inspected if there is reason to believe that a non-genuine replacement airbag may have been installed. Vehicles with salvage or rebuilt titles, prior airbag deployments, or unknown repair histories may present a higher risk. NHTSA strongly cautions against self-inspection by vehicle owners and recommends inspection by trained technicians.

counterfeit driverside airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN), that have been identified in U.S. vehicles following prior crashes, theft, or noncertified airbag replacements. These inflators are not approved for use, may rupture during deployment, and have caused serious injuries and fatalities. Please see attached announcement, provided by NHTSA, for more details.

display warning messages on the instrument cluster, resulting in the PDW sensor(s) failing to detect nearby objects or triggering multiple false alarms. This condition may be a result of external damage to the PDW sensor membrane or sensor cover from rock chips or road debris, a collision, or previous vehicle repairs or modifications.

This may be due to an irregular disconnection on Verizons communication network. Follow the procedure in this TSB to reestablish the connection by resetting the AVN unit.

This procedure is applicable when noise (whirring, roaring, grinding, rumbling, etc.) is present which gets louder when driving with more speed.
