no trouble codes are currently existing in system.(check has been done)

not trouble codes........flickering occurs when trac system is actually functioning for the condition.

I see only one switch (brake light switch) seems to be functioning ok..today drove car in wet conditions,trac light lit , wheel started spin, trac control started working with trac light flickering then light was out the rest of the drive. however, back on the next trip....???

about to buy a sensor tester but not quite sure if i need....----trac----(light) comes on after driving a mile or so and stays on until car is shut off.(thats the only light that comes on) i can not get any readout codes. sometime car will go a little farther before light again but usually a mile consistently. i think a rear wheel speed sensor is the culprit but not real sure. any sensors on throttle body or engine that might affect this?

THANKYOU VERY MUCH INDEED

I need to replace retaining clips on the black trim upper part of driver door around window. I think the door panel must be removed to remove inner plastic trim? All of the screws that can be seen are removed, but something around door handle is holding........how does it release?

thanks to turbogs300 code 71 problem solved by cleaning out the egr passages in the intake manifold.....carbon build up completely shut off tube.

rechecking items visually and manually disconnecting/reconnecting harnesses.however,having difficulty getting info on how and location points for testing circuits.proceeding slowly.thanks for your info.

Need help........check engine light, trac off light & trac light keep coming on. Have taken to local Lexus dealer, spent $83.00 on diagnostic check and advised of code 71 which they state is EGR related. Also advised these items needed replaced (EGR valve, EGR modulator valve, EGR VSV and decarbon the connector tube from EGR valve to manifold). Everything has been addressed and lights continue to come on. I have reset system and started and idled car to normal operating temperature and allowed to run for as long as 20 minutes with no lights appearing. However, when I drive the car, particularly at 50 miles per hour or above, lights will then come on and stay on until I reset system again. Could it be something other than emissions, i.e. traction control system ?
