Some 2018-2021 Expedition/Navigator vehicles equipped with electronic limited slip differential (ELSD) rear axle may exhibit an illuminated powertrain malfunction (wrench) indicator with diagnostic trouble code (DTC) P0932:17. Check the condition of the wiring harness and connections at the ELSD and the differential control module rear (DCMR). If no problems are found, clear the DTC and test drive. If the condition returns, refer to Workshop Manual (WSM), Section 308-07A.
