Lexus / Toyota and non-OEM tester reset

[Krys Kozlowski]

Hi All,

A very handy bit of knowledge, at least for the Lexus / Toyota crowd is the occasional OBD II tester error. What we have on the 3UZ FEs and probably a couple of similar Toyota and Lexus engines is a distaste for non-OEM OBD II testers. These tend to set a VSC error on the dash board after pulling codes from the car.

First of all, DO NOT PANIC. You most likely did not break it.

The step by step is as follows.
1. get yourself a piece of wiring. 1sqmm (audio jack cable) will do the trick, whatever that is in inches 😉
2. put the key in the ignition and set it to off.
3. hot-wire OBD pins 4 and 14 on the vehicle connector underneath your dash or ashtray or wherever

4. turn key to ON, but don’t turn on the engine.
5. when VSC TESTING appears in your dash (after about 3 seconds or so), turn the key to OFF, and remove the wire from the ports.

Voila

A quick word on cheap OBD2 scanners / OBD2 to USB plugs.

I had a scanner before and I really liked it, but well, clumsy me, it didn’t last forever. So I decided to get myself one of them newfangled USB devices, perhaps get a little more out of the testing, I thought, new software and features, I thought. Enough said, bought one for about 20 USD from ebay. When I tried it out on our IS300, the only thing that connector di was to blow the OBD fuse in the passenger side compartment. Took me a while to find it too.

So I got myself a USD / OBD2 connector designed by a German TUEV engineer, for about 15 times the price, and it worked. You always get what you pay for I guess 😉
