Mackpro Posted December 12, 2017 Share Posted December 12, 2017 Do you know what the fault code number was? There was a issue on the MP-8's where they were waiting on a software update but that came out last month. We rarely sell a MP-7 around here so we dont get to work on many newer ones.

snowdogMP7 Posted December 13, 2017 Author Share Posted December 13, 2017 P245900 fault code Quote Link to comment https://www.bigmacktrucks.com/topic/51935-2016-granite-awaiting-software-update-for-regen/#findComment-387321 Share on other sites More sharing options...
Mackpro Posted December 13, 2017 Share Posted December 13, 2017 Yes dealer is correct. Solution: If the truck is a Mack MR/LE and along with this fault code there is request for frequent parked regenerations (hourly or daily) refer to TT-020-2015 FG - 25; Vehicles Requesting Frequent Regenerations ( hourly to daily ) - found in the Trucks Dealer Portal under the Service Tab - Tech Support - Tech Support Tips or click here. Parked regenerations once every 30-40 engine hours is normal on stop and go vehicle applications. If the only complaint is MIL for P2459 ( more frequent during winter months ), then use the following recommendation. 1. Do not replace any components. 2. Recommend parked regenerations once every week or sooner. 3. A Software Release ( SW ) release is planned to address the root cause for this fault code. This CBR will be updated at that time.

snowdogMP7 Posted December 13, 2017 Author Share Posted December 13, 2017 Problem is the truck won’t let me do a parked regeneration we’ve had the truck since new and it has never let me regenerate at our facility Quote Link to comment https://www.bigmacktrucks.com/topic/51935-2016-granite-awaiting-software-update-for-regen/#findComment-387366 Share on other sites More sharing options...
Mackpro Posted December 13, 2017 Share Posted December 13, 2017 Hopefully the now software will be out soon. I think we waited 2-3 months for the last MP-8 updated engine software to fix a fault code issue.
