PROBLEM
Certain D6N Track-Type Tractors equipped with AccuGrade Ready Option (ARO) have the AccuGrade CAN lines (wire IDs L854 and L855) connected to the engine Electronic Control Module (ECM) at J1:20 and J1:21. This connection causes the engine RPM to drop when the CD700 display starts as a result of overloaded CAN data traffic.
