01-016-15-30672017-06-07. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL; ENGINE; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). SOME VEHICLES MAY EXPERIENCE THE CHECK ENGINE LIGHT ON WITH DTC P0421:00 (CATALYTIC CONVERTER SYSTEM) WITHOUT EXPERIENCING POOR ENGINE PERFORMANCE OR MISFIRE (MITSUBISHI PCM ONLY). THIS IS CAUSED BY IMPROPER CONTROL LOGIC OF THE PCM THAT MAY DETECT FALSE ERROR OF THE A/F SENSOR, RESULTING IN FALSE DETECTION OF P0421. TO CORRECT THE PROBLEM, THE CONTROL LOGIC OF THE PCM HAS BEEN CHANGED. CATALYST MONITOR FUNCTION EXPLANATION • THE PCM MONITORS THE OXYGEN STORAGE AMOUNT PROPORTIONAL TO CATALYTIC CONVERTER PURIFICATION CHARACTERISTIC. • THE PCM STARTS TO MONITOR AFTER RECOVERY (FUEL INJECTION STARTS) FROM FUEL CUT CONTROL. • THE PCM TEMPORARILY CHANGES THE TARGET AIR/FUEL RATIO TO RICH AT FUEL CUT RECOVERY, AND DETECTS THE RESPONSE TIME UNTIL THE HO2S OUTPUT SIGNAL OUTPUTS THE VOLTAGE ON THE RICH SIDE. • IF THE CATALYTIC CONVERTER PURIFICATION CHARACTERISTIC DETERIORATES, THE AMOUNT OF THE TIME UNTIL THE HO2S DETECTS THE VOLTAGE ON THE RICH SIDE IS SHORTER COMPARED TO THE NORMAL PURIFICATION CHARACTERISTIC AS SHOWN. THE PCM DETECTS A CATALYTIC CONVERTER MALFUNCTION USING THIS CHARACTERISTIC.
01-018-15-30702017-06-07. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL; ENGINE. SOME VEHICLES MAY EXPERIENCE THE CHECK ENGINE LIGHT ON WITH DTC P2610 AND P2507 STORED IN MEMORY AFTER ENGINE START AND ROOM FUSE 15A (A) REMOVED. • P2610:00: INSTRUMENT CLUSTER INTERNAL ENGINE OFF TIMER PERFORMANCE PROBLEM • P2507:00: PCM BATTERY VOLTAGE LOW INPUT AS A PAST MALFUNCTION, THE CUSTOMER WILL NOT NOTICE IT (NO WARNING LIGHT ILLUMINATED), BUT THE DTC MAY BE FOUND DURING A VEHICLE SERVICE. P2507 IN THIS SITUATION IS ONLY APPLICABLE ON 2016 AND LATER MODELS. THIS IS CAUSED BY THE ENGINE BEING STARTED 3 OR MORE TIMES AFTER A SHORT DURATION OF ENGINE OFF (LESS THAN 15 SECONDS) WITH THE ROOM FUSED REMOVED.
01-019-15-30722017-06-07. Service bulletin. ENGINE; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. SOME CUSTOMER USING “FLEXIBLE” SETTING FOR OIL CHANGE IN THE MAINTENANCE MONITOR MAY NOTICE THAT THE OIL CHANGE DUE NOTIFICATION WILL NOT WORK BECAUSE OF IMPROPER CONTROL LOGIC OF THE PCM. THIS TSB IS APPLICABLE FOR THE FOLLOWING CASES. • THE OIL CHANGE DUE NOTIFICATION DOES NOT COME ON, EVEN AFTER MILEAGE EXCEEDED 10,000 MILES. • OIL LIFE IN THE CENTER DISPLAY IS STILL LESS THAN 40% EVEN THOUGH THE MILEAGE EXCEEDED 7,000 MILES. TO DISPLAY “FLEXIBLE” SETTING AND “OIL LIFE” ON THE CENTER SCREEN, SELECT THE “APPLICATIONS” SCREEN, “MAINTENANCE”, THEN “OIL CHANGE” TAB. FOR COMPLETE DETAILS, REFER TO THE “MAINTENANCE MONITOR OPERATION PROCEDURE” IN THE WORKSHOP MANUAL.

SOME VEHICLES MAY EXHIBIT THE CHECK ENGINE LIGHT ON WITH DTC P0456 STORED IN THE PCM MEMORY. • P0456: EVAP SYSTEM LEAK DETECTED (VERY SMALL LEAK) THE CONCERN IS MOST LIKELY THE RESULT OF THE CUSTOMER NOT GETTING THE FUEL CAP COMPLETELY CLOSED AFTER FUELING THE VEHICLE. THIS CAUSES A SMALL FUEL VAPOR LEAK AND TURNS DTC P0456 ON.
09-016-15-30412017-06-07. Service bulletin. STRUCTURE:BODY:DOOR. SOME VEHICLES MAY EXPERIENCE A RATTLE NOISE FROM THE FRONT DOOR GLASS WHEN DRIVING WITH THE WINDOW OPEN APPROX. 1/2 TO 4 INCHES (1 - 10 CM). THE RATTLE NOISE MAY BE CAUSED BY INSUFFICIENT HOLDING FORCE OF THE GLASS RUN CHANNEL. TO INCREASE THE HOLDING FORCE, THE SHAPE OF GLASS RUN CHANNEL HAS BEEN CHANGED AND NON-WOVEN PADS HAVE BEEN ATTACHED TO THE GLASS RUN CHANNEL.
09-020-15-30462017-06-07. Service bulletin. STRUCTURE:BODY:HATCHBACK/LIFTGATE. SOME VEHICLES MAY EXHIBIT A CONDITION IN EXTREMELY COLD TEMPERATURES (BELOW FREEZING) WHERE THE HATCHBACK WILL NOT LATCH (HALF LATCH) WHEN CLOSING. THIS IS CAUSED BY THE TOPPER RUBBER, A COMPONENT OF THE LIFTGATE LATCH AND LOCK ACTUATOR (A), HARDENING WHEN THE TEMPERATURE DROPS BELOW FREEZING. THE STOPPER RUBBER HAS NOW BEEN IMPROVED TO ELIMINATE THIS CONCERN.
05-002-15-3019D2017-06-07. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. SOME VEHICLES MAY EXPERIENCE THE CHECK ENGINE LIGHT AND AUTOMATIC TRANSAXLE WARNING LIGHT ON WITH ONE OR MORE OF THESE DTCS STORED IN THE TCM MEMORY (P0842, P0847, P0872, P0877, P0780). • P0842:00 - OIL PRESSURE SWITCH NO. 1 (OIL PRESSURE SWITCH B) STUCK ON • P0847:00 - OIL PRESSURE SWITCH NO. 2 (OIL PRESSURE SWITCH A) STUCK ON • P0872:00 - OIL PRESSURE SWITCH NO. 3 (OIL PRESSURE SWITCH A) STUCK ON • P0877:00 - OIL PRESSURE SWITCH NO. 4 (OIL PRESSURE SWITCH B) STUCK ON • P0780:00 - GEAR SHIFTING MALFUNCTION THIS IS CAUSED BY THE OIL PRESSURE SWITCH A AND/OR B AT THE CONTROL VALVE BODY TEMPORARILY OR PERMANENTLY GETTING STUCK DUE TO CONTAMINATION ENTERING THE PASSAGE. TO CORRECT THE PROBLEM, SOME MASS PRODUCTION CHANGES HAVE BEEN IMPLEMENTED TO REDUCE CONTAMINATION AND IMPROVE THE DTC DIAGNOSTIC LOGIC.
01-021-15-30822017-05-31. Service bulletin. ENGINE. SOME VEHICLES MAY EXHIBIT A CREAKING NOISE FROM THE ENGINE COMPARTMENT WHEN THE VEHICLE STARTS MOVING AND/ OR DURING TRANSMISSION SHIFTING. DUE TO PRODUCTION TOLERANCES, SOME NO. 4 ENGINE MOUNT RUBBERS WERE FILLED WITH EXCESS OIL. THIS MAY CAUSE HIGHER THAN NORMAL PRESSURES AND A NARROWER INTERNAL GAP. AS A RESULT, A STICK-SLIP NOISE MAY OCCUR AT THE CONTACT SURFACES WHEN THE ENGINE SHAKES BACK AND FORTH.

SOME VEHICLES MAY EXPERIENCE A ROUGH IDLE WITH THE CHECK ENGINE LIGHT ON AND DTC P0015 / P0524 STORED IN MEMORY.•P0015:00 - EXHAUST CMP TIMING OVER-RETARDED•P0524:00 - ENGINE OIL PRESSURE TOO LOWTHIS IS CAUSED BY A DROP IN ENGINE OIL PRESSURE DUE TO A PIECE OF FOREIGN OBJECT STUCK ON THE OIL PUMP PRESSURE RELIEF VALVE OR OIL CONTROL VALVE (OCV). THE TEMPORARY ENTRY OF THE FOREIGN OBJECT TRIGGERS A CHECK ENGINE LIGHT ON, BUT ROUGH IDLE WILL NOT BE PRODUCED UNTIL A LATER TIME.
09-016-16-31582017-05-30. Service bulletin. SEATS. AT PDI OR WHEN NEW VEHICLE IS DELIVERED, SOME CUSTOMERS MAY COMPLAIN ABOUT WRINKLES ON THE LEATHER SEAT CUSHION AND/OR SEAT BACK SURFACE.CUSTOMERS HAVING THIS CONCERN SHOULD HAVE THEIR VEHICLE REPAIRED BY A QUALIFIED UPHOLSTERY REPAIR SPECIALIST USING THE FOLLOWING REPAIR PROCEDURE.
02-009-16-31552017-05-30. Service bulletin. STEERING: STEERING WHEEL/HANDLE BAR. SOME CUSTOMERS MAY COMPLAIN THAT THE STEERING WHEEL IS OFF CENTER MORE THAN 3° EVEN WHEN DRIVING STRAIGHT ON A FLAT ROAD.
05-002-16-31292017-05-26. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION. THE NEW SKYACTIV-DRIVE FW6A-EL AT USES “AUTOMATIC TRANSMISSION FLUID (ATF) TYPE: FZ”. ONLY USE “ATF-FZ” TO FILL OR TOP OFF THE FLUID LEVEL. ATF-FZ IS SPECIALLY DESIGNED FOR USE IN THE SKYACTIV-DRIVE SERIES AT. IT IS A LOW VISCOSITY FORMULA WITH LESS FRICTION FOR BETTER FUEL ECONOMY. NOTE: ATF-FZ IS COLORED BLUE FOR EASY IDENTIFICATION. TO CHECK THE FLUID LEVEL, REMOVE THE BOLT, THEN REMOVE THE DIPSTICK. THE DIPSTICK IS MARKED WITH A “FZ” ON SKYACTIV-DRIVE FW6A-EL AT. WHEN FINISHED, INSERT THE DIPSTICK AND INSTALL THE BOLT.
09-003-16-31302017-05-26. Service bulletin. EXTERIOR LIGHTING:TAIL LIGHTS; EXTERIOR LIGHTING:HEADLIGHTS. SOME CUSTOMERS MAY COMPLAIN OF CONDENSATION/FOG INSIDE THE FRONT (HEADLAMP/HEADLIGHT) OR REAR (TAILLAMP/TAIL-LIGHT) COMBINATION LIGHTS. THE RECENT NEW MODELS HAVE BEEN FITTED WITH A CLEAR LENS WHICH CAN CAUSE THE SYMP-TOM TO BE MORE NOTICEABLE, HOWEVER, IT DOES NOT AFFECT THE PERFORMANCE OF THE LIGHT. THIS CONDENSATION/FOG IS A NATURAL PHENOMENON THAT OCCURS WHEN THERE IS A FAIRLY LARGE TEMPERATURE DIFFERENCE BETWEEN THE INSIDE AND THE OUTSIDE OF THE LIGHT HOUSING. IT IS NORMAL FOR VERY SMALL WATER DROPS TO APPEAR IN CERTAIN LOCATIONS ON THE LIGHT UNITS WHERE THE AIR IS STAGNANT (CONDENSATION), MAKING THE LENS LOOK WHITISH (FOG). THIS HAPPENS MOSTLY IN THE CORNERS AND NARROW SPACES, AND WILL TYPICALLY CLEAR DURING WARMER AMBIENT TEMPERATURES, OR WHEN THE LIGHTS HAVE BEEN ON FOR SOME TIME. EXPLAIN TO THE CUSTOMER THAT THIS IS A NATURAL PHENOMENON AND NOT A QUALITY DEFECT. DO NOT ATTEMPT REPAIRS AS THIS IS CONSIDERED NORMAL, AND IS NOT COVERED UNDER WARRANTY. REPLACING THE LIGHT UNIT WILL NOT CORRECT THIS SYMPTOM.
05-001-15-29202017-05-25. Service bulletin. POWER TRAIN:CLUTCH ASSEMBLY. SOME VEHICLES MAY EXHIBIT ONE OF THE FOLLOWING CONCERNS: • HARD TO SHIFT INTO 3RD, 4TH, 5TH, AND/OR 6TH GEAR. • SOMETIMES THE SHIFTER MAY JUMP OUT OF 3RD GEAR OVER A ROAD BUMP WHEN ACCELERATING AFTER DECELERATION AT 25-40 MPH (40-65 KM/H) THIS IS CAUSED BY A FAILURE OF THE RELATED CLUTCH HUB(S). TO CORRECT THE PROBLEM OF HARD SHIFTING, THE SHAPE OF THE 3-4 AND 5-6 CLUTCH HUB HAS BEEN CHANGED. A SURFACE TREATMENT HAS NOW BEEN ADDED TO THE 3-4 CLUTCH HUB TO PREVENT 3RD GEAR FROM JUMPING OUT.
