C. The lengths of the WSS overlay harness required will vary based on the wheelbase of the vehicle. See ‘Determine Vehicle Wheelbase’
below.

d. Allthe harnesses listed in Table WABCO Harness Part Numbers 5 will require trimming to length and termination at the 76-pin
bulkhead connector BHB. See Fig. 3 for image of a typical WABCO ABS Harness and Fig. 4 for bulkhead connector BHB location.

€. Choose the closest available harness length in order to minimize harness waste when trimming to length

f. Installation of the terminal part number 23-13211-410 (Qty: 8 Nos.) requires crimping tool SPX J-38125-6 (non-ratcheting) or SPX J-
38125-7 (ratcheting)

we Note:

g. Carefully mark all eight circuits in the four harnesses to be replaced. Remove and replace only one circuit at a time. Use separate
colored tape at each end of the overlay harness in order to correctly identify and avoid mispinning the connector, See Fig. 5.

h. — During the harness replacement, ensure that the 76-pin bulkhead connector BHB is free from moisture or corrosion. If moisture is
detected, clean the connector using compressed air and dielectric spray. If corrosion is found, note that repairs for additional circuits
fall outside the scope of this service bulletin.

i. “Install the overlay harness within the left frame hand rail and secure as needed. After trimming the overlay harness to length, strip

insulation, then crimp on new terminal at BHB connector. For all harnesses, only one terminal part number 23-13211-410 is needed, and
it remains consistent across all. Keep the original wire twist of the overlay harness as close as possible to the respective terminal

location of the bulkhead connector BHB.

j. Verify that the terminals are installed into the correct cavity of the 76-pin bulkhead connector BHB. See Fig. 6.

Frequently Asked Questions

¢ Will NEXIQ USB Link 3 work for the WABCO YRR+ software download?
— No, only NEXIQ USB Link 2 is acceptable in the WABCO program.
e Upon completion of repair, what might trigger an FMI 05?

— FMI 05 indicates an interruption of the wheel speed sensor, indicating an error in the pinning of the
connector during the repair. Refer to the SPN in the code for the wheel speed sensor location.

e Are there instructions for removing the pins in the bulkhead connector?
— See addendum 1 below.
Addendum 1

¢ Carefully pull the red retention plate out of the connector with pliers on the four red tabs, working around the
mounting stud. See Fig. 8.

Validation of Repair

Upon completion of replacement of all four rear ABS harnesses, clear all codes in DiagnosticLink and verify all
wheel speed values remain consistent both while the vehicle is idle and while driven in the dealership lot.
