TSB \- IDENTIFYING HEAD UNIT SOFTWARE VERSION FOR DIRECT EXCHANGE \- This bulletin provides the procedure on how to identify and record the head unit software level on various head unit platforms and generations. - [TSB\-ELE091R1](/bulletins/10116821.md), 2017-08-31, Service bulletin: EQUIPMENT:ELECTRICAL; ELECTRICAL SYSTEM:SOFTWARE. TSB: IDENTIFYING HEAD UNIT SOFTWARE VERSION FOR DIRECT EXCHANGE \- Identifying Head Unit Software Version For Direct Exchange \(ELE091\) \(Rev 1\) \- This bulletin provides the procedure on how to identify and record the head unit software level on various head unit platforms and generations. This procedure will now be required when ordering head units through the Direct Exchange Program \(see Parts Bulletin 91\-961\-0005\). - [TSBELE091](/bulletins/10089354.md), 2017-01-23, Service bulletin: ELECTRICAL SYSTEM:SOFTWARE; ELECTRICAL SYSTEM.

TSB: KDS \- AUDIO UPDATE MODULE \(AUM\) \- THE GDS AUDIO UPDATE MODULE \(AUM\) WAS INTRODUCED IN FOURTH QUARTER OF 2013. THIS SPECIAL SERVICE TOOL \(SST\) WAS DEVELOPED TO IMPROVE THE EFFICIENCY AND EFFECTIVENESS OF UPDATING 2010MY, AND LATER, KIA AUDIO HEAD UNITS USING A GDS, AND NOW, THE SAME FUNCTIONALITY IS AVAILABLE ON KDS. SOME TECHNICIANS MAY NOT BE AWARE OF THE BENEFITS THE AUM TOOL HAS TO OFFER. THE AUM ELIMINATES THE NEED FOR MULTIPLE USB FLASH DRIVES FOR SPECIFIC VEHICLE MODELS AND APPLICATIONS WHICH, IF MISAPPLIED, MAY RESULT IN AN IMPROPER AUDIO SYSTEM SOFTWARE UPDATE AND/OR LOCKED UP HEAD UNIT. ADDITIONALLY, FIELD REPORTS HAVE INDICATED THAT USB DRIVES FOR AUDIO UPDATES ARE EASILY LOST OR MISPLACED. - [TSB\-036](/bulletins/10042573.md), 2011-12-20, Service bulletin: VEHICLE SPEED CONTROL:CRUISE CONTROL; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\). KIA: ON SOME VEHICLES WITH 4 SPEED, INFORMATION IS PROVIDING FOR UPGRADING TRANSMISSION CONTROL MODULES \(TCM\) TO IMPROVE TORQUE CONVERTER CLUTCH WHILE THE CRUISE CONTROL IS ACTIVATED. \*PE - [TSB\-051 REV](/bulletins/10034244.md), 2010-10-29, Service bulletin: ELECTRICAL SYSTEM:SOFTWARE; VEHICLE SPEED CONTROL:CRUISE CONTROL. KIA: AUTO CRUISE CONTROL LOGIC UPDATE FOR UPHILL DRIVING PERFORMANCE IMPROVEMENT. THE ACTION WILL INVOLVE A REPROGRAM OF THE CRUISE CONTROL LOGIC AND IMPROVE ROUGH IDLE AND/OR P0304 LOGIC FOR 2.0L VEHICLES WITH VCM \(VARIABLE CHARGE MOTION ACTUATOR\). \*PE - [TSB\-070](/bulletins/10034236.md), 2010-10-27, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\). KIA: ECM UPGRADE FOR P0304 DUE TO VCM MOTOR VARIATION. PROVIDES THE PROCEDURE TO UPGRADE THE POWERTRAIN CONTROL MODULE \(PCM\) OF SOME MODEL YEAR VEHICLES. REFLASH HAS ENHANCED VCM \(VARIABLE CHARGE MOTION\) ACTUATOR LOGIC TO IMPROVE A ROUGH IDLE CONDITION AT START UP OR A MIL ON AND STORED DTC P0304 SET AT START\-UP. \*PE - [TSB\-030](/bulletins/10032672.md), 2010-04-26, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\). KIA: PCM UPGRADE\-SHIFT HESITATION AND SHIFT DELAY IMPROVEMENT WITH 2.0L AND 4 SPEED A/T \(SA020\). SOME VEHICLES MAY EXPERIENCE SLIGHT SHIFT HESITATION AND/OR TRANSAXLE SHIFT DELAY. THE TRANSMISSION CONTROL MODULE \(TCM\) IS AN INTEGRAL PART OF THE PCM AND SHOULD BE NOTED AS THE TCM IS REFERENCED. \*PE - [TSB\-059](/bulletins/10032670.md), 2010-04-26, Service bulletin: ELECTRICAL SYSTEM:SOFTWARE; ENGINE AND ENGINE COOLING:ENGINE.
