Wow! Rippa that worked great! Totally forgot about this thread, and I had doubts as the guages didn't flash or blink when I did it. And pulled off for a frowned test drive lol.. and WALLAH it worked! Thanks buddy! Awesome Job!

Speaking of which I came on here because I might sell the lexus .. Anyone interested in a 98 GS400, Shaved Doors, Aqua Blue, 19" Rims, Body Kit, etc.. Got a few things it needs fixed, but mechanically it works/runs great. And it's definitely a head turner. Asking around $6999. That's less than I paid for the car a year ago, and barely put 500 miles on the car since then. And fixed a few things!

I'm having the same problem with my IS300. My p/s front abs sensor was cut when I bought the car, I've only had it for two weeks more or less and I have a dead speedo. Is the abs ssor at fault? Can I re-splice the wires for the sensor? PLZ help.

Go inside the car with the wire connected. Put key in ignition to on position but don't start car. Then pump the brake pedal rapidly for 5 seconds. You will see all your indash lights begin to flash on the dash. Take the key out. Turn the car on and drive it, hopefully your speedometer works. If not, then there is underlying sensor or wire issue.
Thank you for posting this. My Speedo was out, I did this procedure and it came right back on.

Thanks!

I just wanted to add my experience to this thread and hopefully it will help others. I was working on a 1998 GS300 today. The speedometer/mileage was not working and the VSC/ABS/VSC OFF lights were illuminated.

I replaced the front left sensor and that fixed the speedometer/mileage problem, but the VSC/ABS/VSC OFF lights were still illuminated. I then replaced the front right sensor and that turned off the VSC/ABS/VSC OFF lights.

so when the problem is fixed, does the mileage on the dash keep going from where it stopped or does the ecu bump it up to where it should be

I just did mine tonight and it works! At least all the way up to about 60mph and then the needle drops. I have to restart the car to get the needle working again. My mileage is picking up where it left off when the needle wasnt working. Any ideas as to why its so intermittent? Could it be that I have a plain old bad intrument cluster? Maybe the needles loose?

Your wheel sensors are the culprit. Take a voltmeter and test the voltage coming off the sensors (2 front and 2 rear) if you get a zero readout then your sensor is bad.

you mean test the resistance don't you? most wheel speed sensors are Variable reluctance sensors so they are passive.
