Prev: Toyota Sales Up 9.8% in November; Lexus Leaps Forward 24%. - seems misleading
Next: Toyota stalling may be linked to on-board computers, electroniccontrol module
From: john on 6 Dec 2009 13:02 Yeah, I think all the recent problems are likely computer related. These ECUs just aren't up to their tasks. The problem, according to NHTSA, may be linked to onboard computers. "The agency indicates the problem could be linked to the onboard computer, or electronic control module.

The ECUs definitely have problems, but please show us a better way that doesn't involve electronics. Carbs worked well, but wasted fuel. Without electronics, are air would be dirtier, we would use more fuel. Please suggest a better way.

They will be the number one phony excuse for anyone involved in an accident, so every day there are many phoney complaints made. This will be the #1 claim, yes officer I hit the wall, my toyota made me do it.

A cable has worked great for 100 years and now they change it.. I feel they've gone too far with the "drive by wire" systems. What's next? Driving by brain waves?? |
