TO CORRECT THE PROBLEM, SOME MASS PRODUCTION CHANGES HAVE BEEN IMPLEMENTED TO REDUCE CONTAMINATION AND IMPROVE THE DTC DIAGNOSTIC LOGIC. NOTE: IF THE VEHICLE ALSO HAS A DELAYED ENGAGEMENT CONCERN, THIS TSB IS NOT APPLICABLE. REFER TO MS3 ONLINE INSTRUCTIONS OR WORKSHOP MANUAL FOR PROPER DIAGNOSIS AND REPAIR PROCEDURE.
01-014-15-3055A2017-06-08. Service bulletin. ENGINE. FREQUENT ENGINE STARTS UNDER EXTREMELY COLD AMBIENT TEMPERATURES MAY RESULT IN OIL SEEPAGE FROM THE ENGINE OIL PRESSURE SWITCH. THIS CONCERN MAY BE CAUSED BY A LACK OF DURABILITY OF THE OIL PRESSURE SWITCH UNDER THESE CONDITIONS. TO CORRECT THE PROBLEM, THE OIL PRESSURE SWITCH HAS BEEN IMPROVED TO INCREASE THE DURABILITY IN COLD AMBIENT TEMPERATURES.

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.

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.
