2009 Lexus ES350. I would like to know the horn relay location please?
USA SPEC CAR ? (MEANS SOLD THERE FIRST) OR VIN TELLS THIS.
I read the SM, service manual to you, horn schematics.
on 2009 cars, best is check all fuse just in case network errors are cause.
ok no BCM here.
so yes the relay clicks , and closes and honks the horn
shows 2 horns but using ground a23 and a24, got rust there>?
the fuse drives a fuse called HORN
10amp
if you do a 2 mean test, and gay1 honks, and guy2 listens to horn really and you hear it click , that tells you 2 things, horn button good
and CLOCK spring, horn pin not broken
and like magic if it did click, now you found it using EARS.
the book says
engine room R/B and J/B (horn relay)
engine bay fuse box has the relays. not cab.
again USA car left hand drive, not UK or other RHD cars.world wide
How do I reset the warning light that tells you when a bulb is out on your license plate
I had this on my ES330 and spent a year trying to solve it. I was driving away from work and my friend yelled at me to stop. He said my upper brake light in the back window was out. I replaced the bulb, and the rear light error went away. It is easy to fix the light unit slides off to the left and lifts up. It takes a small capless bulb.
Let me know okay.
How to remove a 06 Lexus is250 ECU and mainly the junction block mounted inside the case that sits above the ECU
- Locate the ECU: The ECU is typically mounted under the hood of the vehicle, near the firewall.
- Disconnect the battery: To avoid any electrical shock or damage, disconnect the negative battery cable before beginning the removal process.
- 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.
- 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.
- 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.
- 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.
- 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.
Oil light on engine work roughly
It is possible that the issue could be related to low oil pressure in the engine, as this can cause the engine to run roughly. I suggest having a qualified technician take a look at your engine to check the oil pressure and ensure that it is within the acceptable range. Additionally, they should be able to advise you on the best course of action and help you solve any other issues that may be causing the rough running.
2006 Lexus GX470. How to fix the out dated computer?
You can get a cheap scan tool on Amazon for $35. If you want to do it for free, you can disconnect the negative battery terminal for 15 minutes. After that though you will need to know the radio code and you will have to reset the security system.
2003 Lexus RX300 - Front Headlight - How to replace small round 3 inch light
The round bullseye light? I thought that is the daytime driving light but it's not, it is Main or Low beam. I read that the best way to remove those is to turn the wheel and remove the wheel well liner. It gives the best access in that corner. I asked the mechanic at the Lexus dealership because I told him it was hard to get to the lights because of the battery being in the way, and I read that tip. He said "yes it is the easier way".A trick for testing your lights is to park in a mall with a glass window in front of the car. You can go through the lighting options and see what is working.
1999 lexus rx 300 lose of power untill you get to 40 or 50 mph then stop sign, start all over, anybody have a clue?
The problem you're experiencing with your 1999 Lexus RX 300, where the vehicle loses power until reaching 40 or 50 mph and then starts over again at a stop sign, as well as a high-pitched noise that is not normal, could be caused by a few different issues. Here are a few possible causes and solutions:
- Mass air flow sensor (MAF) - The MAF sensor may be faulty and not sending the proper signals to the engine control module (ECM), causing the engine to lose power. A mechanic will need to diagnose and replace the MAF sensor if necessary.
- Throttle position sensor (TPS) - The TPS may be faulty and not sending the proper signals to the ECM, causing the engine to lose power. A mechanic will need to diagnose and replace the TPS if necessary.
- Engine control module (ECM) - The ECM may be faulty and not sending the proper signals to the engine, causing the engine to lose power. A mechanic will need to diagnose and replace the ECM if necessary.
- Exhaust system - The high-pitched noise could be caused by a problem with the exhaust system, such as a leak or blockage. A mechanic will need to diagnose and repair or replace the exhaust system as necessary.
- Transmission - The transmission may be faulty and not shifting properly, causing the car to lose power. A mechanic will need to diagnose and repair or replace the transmission if necessary.
- Fuel system - There could be a problem with the fuel system, such as a clogged fuel filter or a malfunctioning fuel pump. A mechanic will need to diagnose and fix the problem.
It's important to have the vehicle inspected by a qualified mechanic to diagnose the problem and perform the necessary repairs. Some of the issues can be easy to fix, but some require more extensive repairs and knowledge of the systems.
Range readout does not show anymore
Range, <<< seen where?
we cannot see what you see, here.
sorry.
wild guess transmission range fails on the cluster??????????
car drives ok, not told , job 1. yes/no.
well we scan the PCM (means OBD2 port on dash) scan TOOL.
and see why.?
causes are (but the error matters) DTC
1: lost comms from TCM to PCM and cluster brains.
2: transmission PRNDL switch fails but does car drive oK>?
3: wiring related to all that failing.
4: check fuses for blown?

This sounds deeper than a fuse. If you have access to a professional scan tool, monitor the voltage of the sensor in question. If there is no movement, or choppy movement, especially upon acceleration. If there is any discrepancy, replace the sensor.
If you do not have access to a professional scan tool, check for power and ground at the connector using a DMM (Digital Multimeter).
Once those are verified, you will need to backprobe the connector while connected to the sensor, and verify that the signal wire is giving the proper voltage. This, unfortunately, will require a lab scope, which most people outside of a shop would not have access to.
It only gets more technical from there, which will most likely require some diagnostic time at a professional shop.
