Power Light Flashing

[chef_tim]

Trying to help a buddy out, car is about a 92 leggo wagon. He says when he first starts it up the ADW "power" light on the dash flashes for a few seconds. Sounds to me like it is throwing a code. Sound about right to the rest of you? I think if he stops at the ACC possision it should give him the full code. Long=10s and short = 1s, right? Thanks, Tim

flashing power light or AT Temp light at start up is an indicator of a

TCU code, a problem on the last drive cycle. there is a "handshake" for accessing the coeds. you can search for it here "readtranscodes" or "transcodes".

you'll know you found the right procedure when you say "who in the world came up with that convoluted sequence?" AT codes are the most annoying to read as such.
