128142 发表于 2020-08-27 12:51:46 FIELD SERVICE CAMPAIGN BULLETIN Subject: Field Service Campaign D18M2 GHG17 Detroit™ DD13® Software Reprogramming and Emission Label Replacement for Motor Coach Industries, Inc. (MCI®) Issue Involved Detroit Diesel Corporation (DDC) has determined that some certified GHG17 Detroit™ DD13® engines installed in MCI® vehicles will require reprogramming to a minimum of the software and fuel map part number ZGS levels listed below.  MCM software 6.6.0.1 with fuel map part number level ZGS 003  ACM software 7.58.2.0 with fuel map part number: o A0194486954 ZGS 001 (engine serial number 471941S0547134 and higher) o A0194487054 ZGS 001 (engine serial number 471941S0547132 and lower)  CPC software R40_00_000A Some of these units may also need their exempt emission label replaced with a certified emission label. Updated programming and certified emission labels became effective for GHG17 DD13® engines manufactured after August 29, 2018. GHG17 DD13® engines manufactured before August 29, 2018, need the MCM, ACM, and CPC reprogrammed, and some may also need installation of a certified emission label. Note that some engines may already be reprogrammed and have a certified emission label installed. These engines will be excluded from this Field Service Campaign. Reprogramming and emission label replacement corrects various fault code issues such as “SPN: 1636, FMI: 16 – CAC Efficiency Low”, “SPN: 2659, FMI: 0 – EGR Flow Target Error”, and “SPN: 520372, FMI: 16 – SCR Closed Loop Control At Maximum Limit.” There are approximately 457 engines affected by this Field Service Campaign.
