General Information
Western Star 47X and 49X vehicles manufactured from September 12, 2018 through March 22, 2021 that are
equipped with WABCO Anti-Lock Braking System (ABS) controllers log excessive 629-11 fault codes, which can
lead to additional downstream fault codes. The ABS controller will receive a software update to eliminate
erroneous fault codes and ensure proper function. After the software update, the vehicle will require a
recalibration drive for the steering angle sensor.
Procedure
1. Check the base label (Form WAR259) for a campaign completion sticker for SF622 (Form WAR261). The
base label is usually located on the passenger-side door, about 12 in (30 cm) below the door latch. If a
sticker is present for campaign SF622, no work is needed. If there is no sticker, proceed with the steps
below.
2. Confirm that the vehicle ABS ECU part number is listed in Table 1. If the vehicle ABS ECU part number
does not appear in Table 1, check the WABCO TP-19072 Technical Bulletin included in the WABCO
TOOLBOX software package.

3. Park the vehicle on a level surface, shut down the engine, and apply the parking brakes. Chock the tires.
IMPORTANT: For ECUs recently installed in the vehicle, cycle the ignition and allow several minutes
before proceeding with the update process.
4. Check for fault code SPN 520272 FMI 13, ’Steering Ratio Parameters-Out of Calibration.’ This fault code
MUST be inactive before downloading the flash tool.
If Active — Refer to Service Solution 1033682, New Cascadia ABS Fault code SPN for information.
If Not Active — Proceed to step 5.
NOTE: For issues regarding the flash tool download and installation process, call WABCO at 1-855228-3203, or email at [email protected].
5. An mBSP flash tool software installation is required to perform this ABS ECU software update procedure.
Download the latest version of the mBSP flash tool package as follows.

IMPORTANT: If an older version of the mBSP Flash Tool is installed on the laptop, uninstall it. Delete
setup files of any other version such as ‘mbspflashtool300en130a.EXE’ from the laptop.
NOTE: For additional information regarding the mBSP flash tool installation, minimizing laptop
disruption during the installation process, and for links related to adaptor driver software, visit the
DTNA website, https://dtnaecomponents.com/Downloads/mBSPFlashTool/mBSPFlashTool.htm.
7. Install the mBSP Flash Tool using the instructions in the mBSPFlashToolProcedure vXX.pdf.
NOTICE
Before connecting the laptop to the vehicle, disconnect the laptop from the internet and close all other
software, if running. Make sure the laptop DOES NOT enter sleep mode during the software update by
verifying the sleep mode settings. If the laptop enters sleep mode, the download will fail and the ABS
ECU software may not be recovered. If this happens, the ABS ECU will need to be replaced and/or sent
to WABCO for repair.
8. Turn the ignition switch to the ON position.
NOTICE
Ensure the cable is in good condition prior to connecting the laptop to the vehicle. A cable in poor
condition may lead to a failure of the repair, which could result in replacement of the ABS ECU.

IMPORTANT:
• The vehicle battery voltage must remain at 12.4 volts or above during programming. To ensure
good battery voltage during programming, it is recommended to connect an appropriate battery
charger to the vehicle batteries.
• Verify that the selected RP1210 adaptor is updated to the latest driver software. Using an
adaptor equipped with an outdated software version may result in update failure.
9. Connect an RP1210 adaptor to the vehicle’s Deutsch 9-pin connector. The mBSP flash tool software should
be closed. If opened, close it before connecting the adaptor. No other diagnostic program should be running
on the laptop (WABCO TOOLBOX, DiagnosticLink, etc.).
10. Double-click the mBSP flash tool shortcut to open the software.
11. The program will open with a warning note. See Fig. 4. Read the warning note. If the vehicle is secure,
select ‘Yes.’

IMPORTANT: The ECU may not connect automatically due to wrong adaptor settings. To make sure
correct adaptor settings are selected, go to ‘Options,’ ‘Settings,’ ‘Change port.’
NOTE: An error message ‘The detected application version is not supported’ will appear if the ABS
ECU is not listed in Table 2 or if this mBSP flash tool update has already been installed on the
connected ABS ECU.
12. If the ECU does not automatically connect, select the button in Fig. 5, ‘Initialize ECU and switch to
diagnostic mode.’

Fig. 8, Starting the ECU Update
IMPORTANT: If the update process fails at any point, close the mBSP Flash Tool, then cycle the
vehicle ignition. Go to step 10.
The update may be attempted multiple times. Ensure the correct chassis number is entered for the
vehicle, and the same laptop is used on which the failure occurred. If the failure occurs repeatedly,
swap the adaptors and try again.
If programming is still unsuccessful, note the ECU part number, if displayed. Call the WABCO
customer care center at 1-855-228-3203, then select option 1 for technical assistance. As WABCO
may ship a replacement ECU, have the dealership address available before calling.
NOTE: ESC calibration will be required after the flashing process is complete.
16. Once the ECU update is complete, some ECU errors may be present. Select ‘OK’ and close the flash tool
and start calibration mode. See Fig. 9.

17. The ABS ECU is now in ESC calibration mode. Complete the driving portion of the End of Line (EOL)
procedure. After approximately 100 yards of straight-line driving, and the ABS ECU records a 90 to 180
degree turn, the stability lamp on the dash will turn off.
18. Perform a key cycle to complete a vehicle sleep cycle. This will save the calibration data.
19. Save a parameter file from the ECU as proof that the parameter update was successfully completed, and
add it to the vehicle repair order. This can be done in the WABCO TOOLBOX. Launch the WABCO
TOOLBOX software and select ‘Pneumatic ABS/EBS.’ See Fig. 10.

NOTE: Certain vehicles with 8×4 configuration equipped with a pusher axle may not register a fourth
axle within the ‘Wheel Sensor Data’ screen due to vehicle wheel sensor locations, and WABCO
TOOLBOX Plus screen layout. This will not affect the programming, and the parameter update will be
completed successfully.
21. The ABS ECU update is now complete. Verify that no faults are present and that the ABS ECU part
numbers have been updated as shown in Table 2.
