U0208 Lost Communication With Seat Control Module A

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

U0208 says seat control module A has dropped out, mostly a driver's seat unit. The letter is used differently: FCA radio bulletin 08-108-14 (2015 Cherokee, Grand Cherokee, Ram) calls it the heated seat control module and removes a false U0208-00 on the Cherokee with new Uconnect radio software; Audi bulletin 2067722 (Q7 2017–2024, SQ7) finds U020800 with a dead driver seat when road salt under the driver-side sill carpet has oxidised splice B304; Ford SSM 55168 (2027 Expedition, Navigator) sees U0208 in several modules when the driver seat module goes quiet, also stopping the power running boards, with a software fix due. GM's 2011 Saab list names the memory seat module. No MIL.

Likely causes

Splice under the driver-side carpet corroded by salt water (Audi Q7/Q8)
Seat module or radio software (Ford SSM 55168, FCA 08-108-14)
Seat harness pinched or unplugged under the seat
Seat module faulty

Symptoms

  • Power or memory seat does not move
  • Seat heating or ventilation cannot be switched
  • Power running boards fail (Ford Expedition/Navigator)
