Re: My ETC light is flashing
This could be MANY things, as some have mentioned I have seen a couple ETC cars go stupid and simply require a relearn with vehicle that have had battery issues (2 in the last couple weeks, neither I worked on but coworkers). Especially if your on the original battery its got to be on its last leg!
I have also seen dead PCM's cause throttle control issues, faulty throttle bodys, accelerator pedal position sensor issues... seeing codes stored or active its hard to even narrow down the concern let alone diagnose over the internet. Ultimately what I am getting at is there is not a super common failure that we can point you at blindly with your concern.
