GHG17 GHG17 Detroit™ DD13® Software Reprogramming and Emission Label
Replacement for Motor Coach Industries, Inc. (MCI®)
Detroit Diesel Corporation (DDC) has determined that some certified GHG17 Detroit™ DD13® engines
installed in MCI® vehicles will require reprogramming. 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 with GHG17 DD13® engines
manufactured after August 14, 2018. GHG17 DD13® engines manufactured before August 14, 2018,
will need the MCM, ACM, and CPC reprogrammed, and some will also need to have a certified
emission label installed. Reprogramming and emission label replacement will correct various fault code
issues that may result in customer dissatisfaction.
Note that some engines may already have been reprogrammed and certified emission label
installed and will be excluded from this Field Service Campaign.
Records available to us indicate that your vehicle has one of the eligible engines. Instructions for this Field
Service Campaign have been sent to your local Detroit Diesel Authorized Repair Facility and the labor time
required to perform this software update is approximately 0.6 hours.
Please contact a Detroit Diesel Authorized Repair Facility to arrange to have the Field Service Campaign
performed. To locate an authorized facility, search online at https://demanddetroit.com/find-a-dealer/
You must make an appointment with the repair facility at least two weeks in advance of the actual
repair in order for the repair facility to order and receive the certified emission label to complete this
Field Service Campaign. Failure to provide advance notification to the repair facility may result in a
delayed repair.
This service will be completed for you at no charge, prior to September 30, 2019, under the provisions of
this notice.
We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your
continued satisfaction with our products.
