Vehicle Overspeed Parameters
Vehicle overspeed parameters can be set with the DDR or programming station. Customer
decided parameters log vehicle overspeed codes. The parameter is typically set for +3 mph and +5
mph greater than the current vehicle speed limit; e.g. vehicle speed limit 65. Maximum overspeed
limit is 68 and maximum speed no fuel is 70. Setting both to zero disables the function.
NOTE:
Remember to review these figures if Fuel Economy Incentive is activated.

Vehicle Speed Limiting
