Bulletin Summary
The current M/MA software was designed with the pump output for wire 40 and wire 41 backwards. Because of this wiring harness design, the gear pump and vane pump configurations cannot be controlled in the same manner. Software version 8.1.18 or later corrects the programming issue.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
