E4 ESC End of Line Calibration
Procedure
This procedure is performed as part of the final assembly of the
vehicle at the manufacturing site. Also, this procedure must be
performed in the field by a trained technician if components are
replaced such as the Steering Angle Sensor (SAS), the Electronic
Stability Control (ESC) module or the ESC Electronic Control Unit
(ECU). This calibration should also be performed when a major
steering repair or replacement has taken place.
The process consists of two operations. The first one is the SAS
Calibration while the vehicle is stationary, followed by the ESC
Initialization while driving the vehicle. The status of the ESC End of
Line (EOL) procedure can be verified using one of the following
allowed faults.
앫 SAS not calibrated — SID 89, FMI 13
앫 ESC initialization required — SID 88, FMI 13
앫 ESC initialization not completed — SID 88, FMI 1
Additional faults must not be active. Any other faults must be
resolved before one of the main menu items is available.
NOTE: To prevent incorrect activations, SAS Calibration and ESC
Initialization must be done separately. It is necessary to perform the
SAS calibration prior to the ESC initialization.
For any questions or assistance, please contact WABCO North
America Customer Care at 855-228-3203 or visit wabco-na.com
for further details.
SAS Calibration
NOTE: The SAS Calibration must be done after a front wheel
alignment has been performed.
Depending on the software version used, there will be two options to
communicate with the vehicle:
앫 If you are using TOOLBOX™ Software version 11 or higher and
a vehicle with ECUs E4.4b or higher, Tractor ABS J1939
communications can be possible. Figure 9.1.
앫 J1708 communications are possible with any TOOLBOX™
Software version and any ABS ECU. Figure 9.2.

In the Main Menu, select J1939 Tractor ABS or J1708 TOOLBOX™,
then Tractor ABS. The ABS Main Screen will appear. Figure 9.3 and
