Summary
Revised Field Service Campaign for Cascadia/49X ABS MBSP+ Controller Software Update. REVISION: The work instructions have been revised. Certain vehicles have a WABCO Anti-Lock Braking System (ABS) controller that logs excessive 629-11 fault codes which subsequently lead to additional downstream fault codes.

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 process of software
update, by verifying the sleep mode settings. If the laptop enters into sleep mode during the process of
software update, the download will fail, and the ABS ECU software may not be recovered resulting in
replacement of the ABS ECU, or shipping it 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equipped with an outdated software version may result in update failure.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 a 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 (ToolBox, DiagnosticLink, etc.).
10.
Double-click the mBSP flash tool shortcut titled ‘mBSP Flash Tool (en) V1.41’ to open the software.
See Fig. 25.

Fig. 30, Starting the ECU Update
IMPORTANT: If the update process fails at any point, close the mBSP Flash Tool program, 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 the 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.
