Hello:
Thank you for this advice.
It really works!
I followed the steps and it worked to turn off the VSC light on my dash. I have a 2003 LS 430 (USA) with 186,000 miles. I recently had the alternator replaced and that's when the VSC light came on. Some added tips. There are two rows of holes. The paper clip goes in the holes on the top row for the first step. Then one on the top row and one on the bottom row for second step. Top row is one closest to steering wheel.
Second tip. It is very hard to crawl upside down to look up at diagnostic socket. What I finally did was hang upside down by holding onto the steering wheel and sliding up under the dash. You need a free standing light to shine upwards so you can see where to install the paper clip or other wire. I used insulated bell wire with the insulation removed from the tips.
This trick really worked on my USA car.
Thank you!
Now I need to research how to turn off the red airbag light on my dash.
