1. Scope--This procedure covers two-wheel drive vehicle operation and single-axle electric dynamometer load coefficient adjustment to simulate track road load within the speed range of track testing and the dynamometer inertia and road load simulation capabilities.

1.1 Purpose--To provide a uniform procedure for adjusting an electric chassis roll dynamometer to provide accurate simulation of the resistance which must be overcome by the vehicle powertrain to maintain steady speed on a flat road, as determined by track coastdown tests on that vehicle.
