SmartTrac™ 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.
SAS not calibrated — SPN 1807, FMI 08
ESC initialization required — SPN 520210 FMI 14
CAUTION
Additional faults must not be active. Any other faults must be resolved before one of the main menu
items is available.
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 the WABCO Customer Care Center at 855-228-3203 or

SAS Calibration
The SAS Calibration must be done after a front wheel alignment has been performed.
The E8 software version requires TOOLBOX™ Software version 12.7 or higher to communicate with the
vehicle. Hydraulic ABS J1939 must be used to complete the end of line procedure.
In the Main Menu, select Hydraulic ABS (J1939), the ABS Main Screen will appear.
