Manufacturer summary

Original wording in English

AXLE ASSEMBLY, Rear Complete On dual rear wheel high output trucks displaying wheel speed DTCs C003A-2F RR WSS or C0037-2F LR WSS, but for which diagnostics are not finding any hardware problems, and for which the customer narrative includes comments about driving on highway rumble strips, please do not replace the axle, wheel speed sensors, harness, and/or ABS module. Engineering is working to determine a root cause, please clear the codes and encourage the driver to avoid rumble strips until a repair becomes available. If this issue does not describe your concern, please proceed with repair.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
