OPERATION 121
MACK Road Stability Advantage (If Equipped)
The MACK Road Stability Advantage (RSA) is based on the Bendix® ABS-6 Advanced
with ESP® (Electronic Stability Program) System. The RSA system aids the operator
in maintaining control of the vehicle in the event of a jackknife or rollover situation by
applying select brakes and reducing engine power as required by the specific situation. The
RSA system, which is integral with the anti-lock brake system, uses the standard ABS
components (such as wheel speed sensors and modulator valves) along with a Steering
Angle Sensor (SAS-60™) and a Yaw Rate/Lateral Acceleration Sensor (YAS-60™) package
to provide information concerning vehicle movement to the Advanced EC-60™ Electronic
Control Unit.
In most cases, vehicle repairs will not affect function of the MACK RSA system. However,
the following repairs require recalibration of the SAS-60™ sensor after the repair has been
made:
•
Removal and reinstallation or replacement of the SAS-60™ sensor
CAUTION
Installation of an aftermarket steering wheel may damage the SAS-60™ sensor. It
is therefore recommended that the OEM steering wheel NOT be replaced with an
aftermarket wheel.
•
Any repairs to the steering system or front suspension such as:
•
Replacement of front springs
•
Replacement of king pins or bushings
•
Replacement of the steering gear
•
Replacement of the drag link, cross steering tube or ball sockets
•
Replacement of the front spring hangers
•
Replacement of the steering column
•
Front end alignment
•
Disconnecting the steering column from the steering gear, or the steering linkage
from the steering gear
WARNING
Failure to recalibrate the steering angle sensor after performing any of the repairs
mentioned above, may affect proper function of the RSA system, resulting in a loss of
vehicle control due to system intervention at inappropriate times.
