That light is telling you that your brakes are near worn and to have them serviced.

that light is for the water, add some more water in your contenner that light sould turn it off I have found that there is a very fine line between too full which causes an overflow from the coolant reserviour, and too low which turns on the light. An annoying feature on the LS. vbdenny

For a second generation IS250: Hold down the the odometer reset button and press the start engine (without your foot on the brake to prevent from starting) to switch to the acc. mode, continue holding the reset button for about 5 sec until the visual countdown ended et voila, your system has been reset.

Get a manual on your car from the parts store for about $18 and it will help on the next repair.

The Saturn Ls1 that I own I have replaced the brakes twice and each time I am forced to buy the brakes frome Saturn although this car is 5 years old the parts for this 2000 Saturn LS1 are not allowed to be sold on the open market.

Hey Michael==Go to auto zone and they will read the codes for free and it will tell what direction you should go to repair your car. GoodluckJoe

Autozone can only scan 1996 and newer lincolns!

They CAN check the pre 96 ones but it requires them to actually look for the right connector and they are usually too lazy to do it so they just say they can't unless it's 96+. 96 got a standardized scanner across all make/model lines in US so just one code reader. When they are slow, they have checked the codes on my 94 Towncar several times. Half the time, I was told they couldn't do pre 96's and the other half they did it. They will also tell you that unless the check engine light is on, codes can't be read. That is also untrue. Codes are stored in memory for IIRC 500 ignition cycles or when the battery is disconnected, the codes are cleared.

One thing I have learned about Towncars is that damn EGR valve causes carbon buildup. Remove the throttle body. Right under that is a gasket. Go to your nearest napa store and get the gasket, it's like 3 bucks I think. Anyway, after you remove that you will see a small half canal that hides under the gasket. Most likely and it happens on all towncars especially if you use low grade garbage gas it will be clogged with carbon, get a can of gum out carbareutor cleaner and just clean it.try to clean it all nice and squeaky, Put the throttle gasket in(new one) and put back the throttle, reset the computer and let her fly, you see that check engine light go away.

that is so true!! went today to get a reading and told me only 96 on. it is lie, because last week the guy did the diagnostic for me. unfortunately he wasnt there today.

On my 95 LS400 left low beam it was necessary to first remove a circular plastic cover. Just depress a tab and it will come off. Next the electrical connector is encased in a rubber sleeve-gently pull the sleeve back from the connector and disconnect the connector from the light . The old light is held in place by a spring under tension --- release the tension on the spring by lifting it from a small slot and the old bulb comes out easily. Be careful not to touch the new halogen bulb with your fingers.

I have attempted to fix my 94 Lexus LS400 instrument dashlightsa couple of times to no avail.Finally,I had it repaired at LexusTech.com in September 04, I am very happy with their work .

A common problem on these cars. So far mine has not had a problem. There is a very detailed description of how to fix this on the lexusownersclub.com LS400 forum.vbdenny

I have a 1993 LS400 that has had several different issues with the instrument panel. 1)The needle on the speedometer went out ~110,000mi - I eventually had the dealer replace it for big $$$. 2) Beginning ~120,000mi the entire instrument panel would flicker in cold weather until the car was fully warmed up - I found an electrician expert who diagnosed this problem on his own LS400 & offers repairs via eBay at about $600 LESS than the dealer wanted. 3)The time / temp LCD became unreadable "smudged" especially in cold weather. I found replacement LCD on eBay from several different vendors & installed myself. Car is currently at 140,000mi and instrument panel is fine!

Usually the route is on the underside of the hood.

They are kind of tricky to route. Look in the owners manual as there is a diagram in there I believe. If you don't have an owners manula, contact a Lexus dealer and they will order you a new one for free. They will also provide you with a complete printout of all dealer service done on this vehicle done at any Lexus dealership. For specifics go to lexusownersclub.com and check their boards, they have a wealth of Lexus information. vbdenny

The cover slides straight forward. Firmly pull, sliding toward the front of the car to release the latch. Gently lift straight up (the wires will remain connected to the lamp socket. Twist out bulb socket (counter clockwise) remembering the orientation for it's return trip (it's a confusing socket).

For the 2000-GS300 you will need #000 Philips screwdriver, remove the small screw and pry the case open nearest the screw hole. The upper portion of the case has a strong snap like hook that holds it together. Its pretty hefty and seems to be the only way to open it. Inside you will find a module about the size of a quarter that has two more #000 Philips screws securing it. Remove them and under that cover you will find a CR1616 battery. Use a small flat blade screwdriver to lift the free edge of the battery and slide it out away from the retaining tabs.

For a Lexus IS 250 /AWD Key-less Entry Key FOB 2006 and newer:

1. Take out the mechanical key from your fob.

2. Put a flat head screwdriver into the inset space...just inside of the mechanical key slot....and gently turn/pry it. This will pry open the fob.

3. Remove the old battery and replace with a new Panasonic CR1632 battery..positive side facing up.

4. Replace the cover of the fob by first pressing on the bottom then the top (The top is the side where the mechanical key is inserted)

The traction control systems seem to develop problems at this age. Look on lexusownersclub.com in the LS400/430 forum and post a question. I get most of my Lexus repair answers from this board. Also check on lextreme.com as he offers several tutorials. . VBDENNY

Have the Codes read by a code scanner; some autoparts stores do this with out charge (Autozone in Texas does this).

You can also purchase a code scanner, but they range from $150 - $500.

I have a 1990 LS400 and I have never heard of a timing reset button. The timing is set by the timing belt and controlled by the computer. Let me know if you find out there is such a thing. vbd

Hey Clifton==Takeit to Auto zone and have the codes read free. GoodluckJoe I have had mine tested and there is an error in the computer that gives false readings such as check engine, hot engine, etc. There is a computer chip that needs replacing, but I am told that the exact same number must be on the replacement computer chip. When each system is tested through the computer individually, it will test as ok, or in fine operation, yet the lights will continue to display randomly. This error could not be reset, only a replacement of the computer chip is what my mechanic told me to solve the problem. Until replacement, you will have to watch the fluids, temp, etc. manually (old fashioned way of checking the dipsticks & fluid levels) until this chip is repaired.

If you are asking for the location of the Turn Signal Flasher Relay, it is located in Junction Block 1A (under dash on drivers side). Block 1B has the fuses, Block 1A the relays. The flasher is the small relay at the end opposite the group of four (4) relays.

The timing is computer controlled, there is no adjustments.

I know this is a little late, but timing could be off because the timing belt is not properly aligned. If the timing belt is installed incorrectly the timing will never be right.

It needs to be charged. You Need To Have Your A/C Serviced. Everyone Including Me ! Needs To Have Their Cars Serviced Regularly. And The A/C One Time At Least A Year. Your Sounds Like A Loss Of Freon. Or Maybe Compressor Trouble. Have It Checked. GOOD LUCK

Don't. They are obsolete analog devices. VBD I agree...If you want an in-car phone an upscale electronics center might have digital in-car phones that you could install in place of the existing analog unit. There are also adapters that allow some hand-held cell phones to be inserted so that they become an in-car phone. LOL.

If it is a red circle with serrated "parenthesis" to the right and to the Left, then it's your brake warning light. The brake sensors are telling you there is something wrong with the brake system, IE: pads, fluid, sensors, etc.

i also have an 1990 ls 400 with ignition wirind promlems. i searched for a few weeks and tried to get the diagram through various mechanics. they all ended up telling me that the dealership would not provide them with it. so, the Lexus dealership is just about the only place to get the wiring diagram. your question was not very detailed so i may not be giving the answer you need. the problem with my auto is that the key will not turn past the "on" position, if this is the case then the easiest solution is to hotwire the starter. this is possible by connecting the positive terminal on the starter syleniod using jumper cables and then turning the key to "on". once this has been set up; simply touch the other positive clip on the jumper cables to the positive terminal on the battery. this should start the car. -CoNtRaFoRm-
