CEL and Trac Off lights on.
So my CEL and Trac Off lights are on. I tried to pull a code today, but I couldnt get the CEL to flash when jumping Te1 and E1. I tried jumping both diagnostic ports, no luck. I just got the O/D Off light to flash non stop.
Im an aspiring technician at a repair shop so after getting slightly frustrated after not being able to flash any codes, I hooked up our SnapOn Verdict w/ the Toyota adapter. I was able to view live data like my fuel trims, O2 sensors, throttle position, etc. but STILL unable to pull any codes! WTF?!
So heres a few symptoms..
--The CEL comes and goes multiple (3-25) times on my 10 mile drive to work.
--Trac Off light and/or Trac lights are intermittent. While they are on, traction control is disabled.
--Occasionally (1 to 3 times a week) the car will start and begin running rough, and no matter how much gas you give it, it will spudder and die. Sometimes it will do this 2 or 3 times, but will ALWAYS start eventually.. it has never left me stranded.
-- Now heres the kicker... occasionally the CEL will flicker, flash and fade/dim.. They arent supposed to do that.. haha WTF?? bad ECU/ PCM??
Well, I would really appreciate any help! The symptoms have been getting worse the past week, so its definitely time to fix it! If you have any questions I would be happy to answer.
