Top 20 2008 Lexus IS 250 Questions & Answers

Have you tried the "valet switch" in the glove box? This switch is used when you don't want a service person in your glove box OR your trunk - only the physical key will open the trunk or glove box. The trunk opener switch under the dash won't work either if the "valet switch" is activated. The switch is located at the top of the glove box on my GS350 - yours may be different.

2008 Lexus IS250 AC low pressure charging port is located on the driver side close to brake booster. I accidentally saw it while changing the O2 sensor.

Adaptive Front lighting System (AFS) is used when for example if it was day time and you entered a dark parking garage the lights would detect and adapt to the lighting environment which will then automatically trigger the Bi-xenon headlights to turn on themselves in order to illuminate the road ahead when the vehicle anticipates it is necessary. It is an automatic feature which turns on by itself for your convenience therefore you wont have to induce any actions, the car does it all for you. And most Importantly (I quote) "the Adaptive Front lighting System (AFS) automatically controls the headlight lighting pattern according to steering angle and vehicle speed to help provide better visibility at night You will need to see the dealer on this, the part that causes this is dealer only

Could be the noise for the chain would be around the belts. It would be a rattle type noise. How many miles on vehicle

Cannot be replaced without replacing the assembly. Sorry. Club Lexis has a thread found here http://www.clublexus.com/forums/is-second-generation/625770-is250-license-plate-bulb-diy-or-new-housing.html

Changing vin by self is illegal if thats what your doingIf its door plates or firewall plates dealer has to order new and you have to take down to mvd and register numbersIf license plate unscrew itBut overall changing any of the cars factory registered plates is illegal without registering them threw proper channels first

if it sound like clicking noise,most likely is the a/c servo motor. you need to inspect which one is it, because there is like 3 of them

the vehicle speed sensors are on all four wheels, not cheap and even if you change them all, the light still needs to be shut off with a anti-lock brake scanner. either live with the light or bring it to a brake shop that has the tool.

it's just your tire inflation pressure warning system. With the same button's you use to input the MPH warning lights or RPM warning lights, go to the Tire pressure settings and change it back to Default / Tire1.. I forget what it says. Look in your manual if this doesnt help... I am positive that this is the cause.

check your thermostat

I have advised on this already.

How do you know the fan is defective, Has the system control module been scanned and the fan circuit failed?? This is a rare failure that is why all the questions. Have the cooling fan tested with a factory tester to assure you are not wasting money on replacing a perfectly good fan motor.

Check the valet switch in the glove box.

I wouldn't think more than $200.00.

Here I have two ways to try:

1.- Way, I think this should work with your model...
a) With your car OFF, place your key in the ignition and turn to "On". Do not start the car.
b) Find the odometer button and press until it reads the total odometer setting, (not the Trip A or Trip B setting).
c) Turn the key to OFF.
d) Place your finger back on the odometer button, press and hold. Then while still holding the button, turn the key back to "On" (not START).
e) Hold the odometer button in until the MAINT REQD light goes out...should take about 8-10 seconds.

2. Way, to reset the oil change system, follow the procedure below:
a) Turn the engine switch OFF.
b) While pressing the trip meter reset knob (→P. 100), set the engine switch to the IG-ON mode. Continue to press and hold the knob until the trip meter displays 000000.

From the owners manual, 4-3 Do it yourself maintenance

Hope help with this.

check to make sure your getting a good connection if your not it causes a high amp draw and burns them out. clean the conectors good

sounds like a bolt may have come off or something, check to see if there are any recalls due to steering columns

1. Locate the ECU: The ECU is typically mounted under the hood of the vehicle, near the firewall.
2. Disconnect the battery: To avoid any electrical shock or damage, disconnect the negative battery cable before beginning the removal process.
3. Remove the cover: There is likely a cover or panel that needs to be removed to access the ECU. This may be held in place with screws or clips.
4. Disconnect the electrical connections: The ECU will have several electrical connections that need to be disconnected before it can be removed. These connections may include plugs, wiring harnesses, and other components.
5. Remove the mounting screws: The ECU is usually mounted to the vehicle with screws. Remove these screws to release the ECU from the mounting bracket.
6. Remove the ECU: Once the screws are removed, the ECU should come out relatively easily. It may need to be lifted out over the junction block or other components.
7. Remove the junction block: The junction block is mounted above the ECU and may be held in place with screws or clips. Once the ECU has been removed, the junction block should be easy to access and remove.

Note: It's important to follow the steps carefully and to be cautious when removing electrical components from a vehicle. If you're not confident in your abilities, consider hiring a professional mechanic to remove the ECU and junction block for you.

Frankly, I would check locally to see if there is a Japanese translator that would do this for you for a small nominal fee. You can check public libraries and courthouses for possible translators. Craigslist is also another good resource. Check local colleges for persons taking Japanese language!

Someone who can translate is willing to do this for a small ($20?) Fee. Good luck!
