Posting this because it seems that some of us have had these lights and just couldn't resolve them, I think this was the fix for me. I tried Techstream, wouldn't do the ZPC and reset the code or turn off the lights. I did the shorting of the OBDII pins 4/12 like the attached shows...actually I'm pretty sure that I didn't have a pin 12, so maybe it's for new models than my 01 LX470. What finally worked for me was from a thread from 2008. This is under the hood on the passenger side, about mid way front to back, mounted on the fender. Says something like Diagnostics on it. For me, it was a little different than described below. I jumped the two, turned the key on and the ABS and VSC lights blinked like it describes in the attachment. That was the whole reset process for me. Check out below, follow the link I'll provide, and see the attached. Try a combination and see what might work for you. Hopefully one of these methods resolves it for you.
Perform this at your own risk. This procedure is good for code 36 and 39 only. Will not work with other code. However, the resetting of ECU code will work for everything else.
Okay, you have to jump E1 and TS on the DLC1 connector which is under the hood right by the passenger side.
Once you jump the two terminals, turn the ignition key to second position but do not start the engine. You will notice that your dash lights are going crazy. Concentrate on the VSC light. Count how many times it blinks before it stops for about a second and starts to blink again. For instance, if it blinks twice then stops and blinks once, that is a code twenty one. If you get code 36 and 39 then you have to reset the yaw rate and deceleration sensor. Heres how to do it.
You must first erase the previous memory by performing the following:
1. Shift the shift lever to P.
2. Turn the ignition switch to 2nd position, do not start engine.
3. With the ignition switch on, jump terminals E1 and TS with a small wire and repeat with a cycle of short and open between terminals 4 times or more within 8 seconc. Check that the VSC light is lit indicating the recorded zero point is erased.
4. Turn ignition swith off.
Once the previous memory is cleared you can calibrate the yaw and deceleration sensor by doing the following:
To calibrate the yaw rate sensor do this:
1. Connect TS and E1 terminals.
2. Turn Ignition on. Vehicle must be stationary and shift lever in Park. Do not rock vehicle or start it.
3. Check VSC light goes off about 15 Second after the ignition switch is turned on. It is normal if the light does not turn off after 15 seconds and starts blinking rapidly. The yaw rate sensor is calibrated at that point.
4. After the VSC light goes off, wait 2 seconds then turn the ignition off.

Saved myself $100 fee
I was driving my 02 LC last night when my VSC and VSC OFF light came on. I proceeded to shut off the car and restarted thinking it would reset itself, but it didn't. Luckily I bought the service manual from EBAY and diagnose the problem by jumping terminal TC and E1 on the DLC1 (located on...
