Some 2013-2017 Edge/MKX/Escape/MKC/Fusion/MKZ/Flex/MKT/Mondeo/Kuga/EcoSport AWD vehicles where diagnosis leads to a RDU clutch issue, a rear drive unit (RDU) service kit is available. Use the vehicle identification number (VIN) in the parts catalog to look for base part 4A232. If clutch assembly (base 4A232) is not listed in the catalog, this message does not apply. For vehicle repairs refer to updated Workshop Manual (WSM), Section 205-02 on ATC clutch repairs. Use causal part 4A232 or equivalent and applicable labor operations.
