MACK Road Stability Advantage

The MACK Road Stability Advantage (RSA) available option certain MACK highway tractors and straight trucks. The RSA system, which based the Bendix ABS - 6 Advanced with ESP (Electronic Stability Program) System, aids the operator maintaining control the vehicle during jackknife rollover events applying select brakes and reducing engine power required the specific situation. This system integral with the anti - lock brake system and uses the standard ABS components (such wheel speed sensors and modulator valves). Additionally , a steering angle sensor and a yaw rate/lateral acceleration sensor package provides information concerning vehicle movement the electronic control unit.

Before delivery the end user , a parameter set tuned for the specific vehicle and the VIN for the chassis are loaded into the ABS electronic control unit. This ensures optimal performance the MACK RSA system for the specific vehicle.

Alterations and modifications RSA - equipped vehicle, such wheel base changes (either lengthening shortening), the addition auxiliary lift axle the removal a factory - installed lift axle, major body changes, such conversion a tractor a truck axle, suspension steering system component modification, are NOT allowed, these changes will adversely fect performance the road stability system. Should such changes unavoidable, the system must disabled having a qualified technician replace the Bendix Advanced - (ABS control unit with ESP) with a Bendix Premium - ECU (ABS control unit without ESP).

Danger

Failure disable the RSA system a vehicle that has been modified altered will result serious vehicle braking and performance including unnecessary system

These interventions could lead a loss vehicle addition disabling the any cab such warning and caution labels relating the Bendix ABS - 6 Advanced with ESP system located the sun visor must and notations must made the operators manuals that the vehicle operator has a clear understanding which ABS options are installed the

The location the yaw rate/lateral acceleration sensor must not altered.

Aftermarket steering wheels must not used. Only OEM - supplied replacement steering wheels should used. During any procedure that involves removal and reinstallation replacement the OEM steering wheel, care must used not crush damage the steering angle sensor which mounted the steering column.

Increasing steering angle beyond maximum NOT permitted. However , steering angles may increased the maximum factory settings required. Refer the applicable steering system service manual for detailed information.

The steering angle sensor must recalibrated following any adjustments changes the steering system.

Changing steer axle and/or drive axle track width

Changing front rear axle brake drums drums having a dif ferent flange thickness

The ABS with ESP ECU requires a precise rolling circumference ratio between the front steer axle and the rear drive axles for optimum performance the For this the system continuously calculates the precise ratio and stores the information the ECU memory

Caution

fectiveness the RSA system relies the accuracy the reported vehicle speed. major changes tire sizes are made, such that changes the vehicle speedometer/odometer settings are required, the ABS with ESP ECU must reprogrammed with the new values a qualified technician.
