Dear Friends/Experts,

I would like to update all of you about my ASR light status.
A week ago (Tuesday last week), after a raining day, I went home after work
my car went to limp mode for about 10 times in busy Ottawa, Canada downtown. I was so shameful. I let the car running for about 15 minutes then be able to drive home. I would guess the electrical short somewhere in the ETA, so I decide to open this up... and see what is inside. When this ETA is opened, I see all the wires insulation (11 of them) are in such bad shape crack, oxide (change color to green), when I touch them, they just turn to dust. All the wires are garbage from the IC board to the connector (about 2 meters or 6 feet long). So I just replace all the wires and the car seems to be OK now. I'm waiting for another raining day to see whether it will happen again or not (I hope not).
If some one's ASR light on and go to limp mode, I would suggest you open the wire bundle cover (by cutting it along the wire) to inspect the wire insulation inside before you open ETA (open the ETA is not an easy job).

I would like to thank all of the friends/experts who made all the ASR problem information accessible and this is the best forum I ever learn.
