DYNAMOMETER TESTING - VEHICLES WITH
ANTI-LOCK BRAKES (ABS)
WARNING: Do not attempt to test ABS
function on a dynamometer
Four wheel dynamometers
NOTE: Before testing a vehicle on a four
wheel dynamometer disconnect the valve
relay. See Electrical Trouble Shooting
Manual.
The ABS function will not work, the ABS warning
light will illuminate. Normal braking will be
available.
Provided that front and rear rollers are rotating at
identical speeds and that normal workshop safety
standards are applied, there is no speed restriction

Two wheel dynamometers
CAUTION: The brake servo and power
assisted steering system will not be
functional without the engine running.
Greater pedal pressure will be required to apply
the brakes, the steering system will require
greater effort to turn the front road wheels.
The vehicle tow connection should be used only
in normal road conditions, ’snatch’ recovery
should be avoided.
IMPORTANT: Use a four wheel dynamometer for
brake testing if possible.
NOTE: ABS will not function on a two
wheel dynamometer. The ABS light will
illuminate during testing. Normal braking
will be available.
If brake testing on a single rig is necessary it must be
carried out with propeller shaft to the rear axle
removed, AND neutral selected in BOTH main and
transfer boxes.
Suspended tow by breakdown vehicle
CAUTION: To prevent vehicle damage,
front or rear propeller shaft MUST BE
removed, dependent upon which axle is
being trailed.
If checking engine performance, the transfer box must
be in high range and drive shaft to stationary axle
removed.
1.
Mark propeller shaft drive flanges at transfer
gearbox and axles with identification lines to
enable the propeller shaft to be refitted in its
original position.

3.
Remove the propeller shaft fixings, remove the
shaft from the vehicle.
If the front axle is to be trailed turn ignition key to
position ’1’ to release steering lock.
