AZEWL Posted August 20, 2021 Share Posted August 20, 2021 RE: 2018 Odyssey Touring. Had/have again warning appear that "Road departure mitigation system off" then goes back on. Now new warning; "Engine management system problem" now on. There are no engine codes stored so hard to make diagnosis. Last summer Honda supposedly did recall service 20- 047 to update for guage control. Suggestion is to take back to Honda for new SoftWare update. Anyone else with same issue?

Trevor Posted August 23, 2021 Share Posted August 23, 2021 Hi.....welcome to the Club I would definitely take it into the dealer to carry out the software update as this may be the reason for the warning lamps which effectively could shut down certain systems until rectified Quote Link to comment Share on other sites More sharing options...
