My persona auto b-line "Check Engine" indicator light suddenly turned "ON" while I was driving today. Car still able to run slowly and keep on mowing with uncontrolled gear and cannot brake either; quite dangerous. Finally rest stop. Try restarting, engine running but when gear is engaged, it jerked with noisy gear sound and move a little.
Call Proton which speculated something to do with ECU / electronics and was asked to remove battery connector (-ve) to reset the system and reconnect after 15 minutes. After reconnecting, light was gone and manage to drive again. Worried but will be heading to workshop for a thorough check.
My pesona is 2008 100k mileage and just changed 4 tyres and front brakes a day before.
Anyone encounter such problem before and mind to share 2nd opinion?

Got the car checked with Proton diagnostic tool i.e. computer and they found two error messages.
Was told that ECU was reset to original settings and after few days of usage, no problem liau.
Not sure when this ECU problem will pop up again.

Thanks les Incredibless.
