U0202Lost Communication With Door Control Module D

  • Generic OBD-II code · Network
How the car detects it
U0202 means the body network no longer hears from door control module D, which most four-door layouts give to the right rear door. FCA STAR case S1908000143 (Rev. A, August 2020) records it on a minivan with Stow 'n Go seating: U0202 for the right rear door module came together with U0201 (left rear), U0230 (power liftgate) and the interior bus codes U0010/U0011, while the owner had a no-start, many lit warning lamps and single wiper strokes. The cause was a chafed body harness beside the right B-pillar, at the outer mount of the passenger seat or along the floor routing next to the seat storage bins, including splice S910. A dead rear window or lock on that side is typical; no MIL.
