I have a 1999 ES300 - 107k miles, which was miss firing intermitantly. The codes I pulled were
1354 (VVT bank 1), (300,302,304,306 misfires bank 2). I replaced the OCV on bank 1 to address code 1354. The condition and codes came back in addition to code 1351. Alldata said 1351 was
caused by a skipped timing belt or a bad ECM. The timing belt was replaced 6 months ago and
is still in correct timing. I purchased a used ECM. The battery was disconected for a few days while the ECM was being shipped. Now the car turns over but will not start, I have tried 2 keys.
The security light on the dash is flashing and the remote fobs are operating normally.
Did I loose the progaming in the security key? If yes, is this from changing the ecm or having
the battery disconnected for an extended period. Finally, Is there a way to correct this short of
towing it to the dealer?

Anyone else have any thoughts? Thanks

Insofar as I am aware there are only two things, sensors, devices, that are unique to VSC, the yaw/acceleration sensor and the stearing wheel position sensor.
Do you remember, have you paid close attention, to what actions (quick jerking motion on the stearing wheel, HARD/fast turn, etc.) you might have taken just prior to the VSC coming on?
My wife drives this car most of the time. She says it may come on more
frequently while driving on a windy road. The shop is going to replace the clock spring
to repair an airbag light. Could this be related?
I was under the impression VSC was simply traction control or is it similar to Mercedes' ESP?

I have a 99 ES300 with 107k miles. It has developed an intermitent VSC light without a CEL.
Once the light comes on it will stay on until the car is shut off. When the car is restarted,
the light is off. The repair shop said no codes have been set.
My extended warranty expires in days so any assistance will be appreciated.
Replaced Ecm, Now Car Won't Start

I thought would pass on what I have learned in regards to replacing ecm's.
A replacement ecm would have to be flashed to be put in relearn mode. You would then insert the
key for 5 seconds (do not turn on) and remove. Repeat for extra keys.
A local automotive locksmith will flash the ecm for $150 (With the ecm out of the car ). I'm not sure what Lexus charges.
An alternate to changing out the ecm is having the current ecm repaired.
There is a company in Houston (www.ecmtogo.com) that will repair the computer for $225.
This eliminates the key hassle and is much cheaper than the $800 Lexus wants for a reman'd ecm or $1300 for a new one.
I would still be interested in feedback from others on this subject.
