Hey all...
I'm new to the club here. I've been wanting to sign up quite some time ago but didn't get around to it. I've had my 1994 gs300 for about 3 years ago. Awesome ride. A couple of days ago, I noticed a few problems with it though. Thought it'll be a good idea asking other lexus owners whether they've had the same problems as i'm having.

First I might tell you a little history of this car. I'm the second owner of this vehicle. No accidents in this car. It's got 200,000 kms on it. Lots of kms but excellent vehicle. Never had a problem with it before. Even now, with both these warning lights on, I do not hear any unusual engine noise or any difference in the performance of the vehicle.I must say that in mid December 06' due to heavy snow/cold weather, the Lexus was parked outside and we didn't drive it during the snow condiitons, but we did start it up to get it warmed up. One day when I go out to warm it up, it wouldn't start, so I pressed hard on the accelerator and then it did start up. Then after the snow, when the roads were clear and nice (no snow), I took it for a drive when I noticed the radio would turn on and off and so would the interior lights, that's when I knew something was wrong so I took a U-turn and brought it back home instead of going farther. Turns out I need a new battery. So, I get a new battery in the car. With the new batttery, the car's running nice as usual. After about a week these two warning lights come on. I take it to a repair shop, they said maybe the batterys not installed properly, so they took out the battery and put it back in. Later that day, when driving home from the repair shop, the warning lights do not appear while driving, so I assume the battery wasn't installed properly before, and its fine now. But the next day , both of the warning lights come back on , so now I assume it has nothing to do with the battery.

I have 2 warning lights that come up when I start the car, and they both stay there while driving, meaning there's a problem.

1st warning light is the 'Malfunction Indicator Lamp'; warns that there is a problem somewhere in your engine electrical system.

2nd warning light is the 'Traction Control System OFF Indicator/Warning Light'; this indicates a malfunction in the anti-lock brake system or engine system. (From Owner's Manual, pg. 29)

One of the other warning lights that I've had come up while driving for a long long time (before the first two appeared) is the 'SRS Warning Light'; a malfunction somewhere in the parts monitored by the warning light system.

I've called the Lexus dealers and they've told me both these lights (the 'Malfunction Indicator Lamp' and 'Traction Control System OFF Indicator/Warning Light') usually come on together, and indicates there's a problem somewhere in the electrical system or someplace else, they'll find out once they hook it to the system. It'll be really appreciated if i could get your feedbacks regarding these issues and whether you've had them come on, repairs, cost, all the things related etc. (From Owner's Manual, pg. 29)

Thanks a BUNCH!!!

Since no repair facility gave you a "trouble code" (usually two digits for OBD-I cars), the first thing to figure out is the code number(s). It's very common for the TRAC light to also come on with the MIL light.

Get somebody to tell you what the codes are, and then it might point you in the right direction. But with an SRS light that also comes up, it sounds like you have two separate issues; a similar issue with all three lights would be a surprise since they seem to light up during different scenarios.

trac-control automatically goes off if you have a check engine light... so there's probably nothing wrong there...


with that many miles, probably EGR, i have both lights on as well, something in the EGR system. We don't have emissions testing where i live, so i just put up with it. Although, i think the check engine might also shut down the heated leather seats
