1998 Lexus Gs 400 - Page 7 - Answered Questions & Fixed issues

does it start with 5%(a tad) right foot throttle pressed? is the IP cluster, IMMO lamp happy? (immobilizer)????? check all fused first? NOT RELAYS. check spark first if engine itself tests good. the classic way for 100 years a test spark plug used. if spark is good then spray test fuel works.? FOR 3seconds if that works, then fueling is bad. (no start) the knock sensor does not kill spark. (it fine tunes spark timing only and only if the engine pings going fast. then scan the pCM OBD2 port for DTC errors. check fuel pressure, at the rail. ok dead fuel pressure. fuel pump relay is called on this car AS EFI MAIN relay HORN RELAY SAME (SWAPS) if the PCM detects spark bad it cuts fuel dead. to prevent crash and burn as see on TV.. the crash sensor also trips the pump off line. page 553 users man FUEL PUMP SHUT OFF SYSTEM The fuel pump shut off system stops supplying fuel to the engine to minimize the risk of fuel leakage when the engine stalls or an airbag inflates upon collision. To restart the engine after the fuel pump shut off system activates, turn the ignition switch to "ACC" or "LOCK" once and start it. https://au.lexusownersclub.com/forums/topic/8368-how-do-i-access-the-rx330-fuel-pump/

There is a fuel pressure Shrader Valve just before the fuel rail. All this stuff can be diagnosed with a professional grade scan tool computer at the stealership, or call out a mobile auto electrician. https://www.google.com/search?q=mobile+auto+electrician+near+me ..

Some throttle pedals when they are replaced need to be calibrated to the vehicle so the electronics understands were the new pedal is for each position as you use the pedal. This is often done using an OBD2 diagnostic system. If you have to pay for this service ask at 4 or 5 different places as prices can be VERY different.

using only electronic key or the metal key.(feature) got park assist option? a no key slot ignition, fails we scant the PCM for cause. the steering is first. so wheels against curb or hard rock>? front tires are free of objects? to unluck it , try both key car came with new and grab the wheel and move it CCW/CW roughly to free the key. shifter is in park I guess. try Neutral? step brake release hand brake, and shift to N then unlock wheel. this answer is flat ground answer only the steps are here Check that the parking brake is set. Check that the shift lever is set in P. Sit in the driver's seat and firmly depress the brake pedal. The "ENGINE START STOP" switch indicator turns green. Pressthe"ENGINESTART STOP" switch if steering lock fails the books states The "ENGINE START STOP" switch indica- tor will flash in green and a message will be shown on the multi-information display. Press the "ENGINE START STOP" switch again while turning the steering wheel left and right!! read page 137 https://assets.sia.toyota.com/publications/en/om-s/OM53839U/pdf/OM53839U.pdf

NO COUNTRY TOLD at all. (sold to day1 new) no VIN told no VIN #8 digit told so we can see what engine is there. and what country, some have 8 engines choices not one I can guess and is a pure engine question the endless hunt here. 2 gas engines here and 1 hybrid , engine is TOYOTA's USA got the 3.5L V6, are you here? USA??? the USA engine has 2 pin CKP sensor, 2 pins is huge clue. crank sensors are on the cranks sure but are on front, middle or rear of crank or even under flywheel, 4 places all engines, 1 is true the cranks shaft has the CKP huge tone while dead front of crank. the service manual covers this, only or you can google this. toyota 3.5 L 2GR-FE V6 cranks sensor location bingo.(note using the real name)

most cars IT is deep in the IP cluster only the SM service manual shows this. door AJAR CHIME THE DOOR OPENS AND DOOR CPU SENDS THIS DATA FACT TO THE CLUSTER, (ON THE MX DATA NETWORK AND THE CLUSTER CHIMES. if the chime is bad say so? we can not guess goals. or too loud or what? here it is

2006 Lexus RX400H hybrid .and long story.(you added and very very good)and if was mine, my story would be same, park it and wonder what to next.?this car is very complex, unlike ICE real cars were simple and still are to a good extent.I do wish you find a good shop to cure all that.a full service manual in hand may do the trick.IDK.good luck! and be SAFE.use the scan tool as the hybrid starts and fails to light off the engine, see DTC code for that.scan before ,during and after failuresand use the pending button too on t he scan tool as here may be marginal or intermittent failuresalso (Im no hybrid guru) but some hybrids do not run the engine (to save fuel) until the battery has some amount of discharge detected.some even have switches to set the mode you want,save fuel or save battery life, IDK this car.

SOME CARS SEATS MUST COME OUT TO REMOVE THE WHOLE CONSOLE TO WORK IT. THE REAL SERVICE MANUAL COVERS ALL THIS FROM LEXUS. SOME LIDS DO NOT COME OFF, WITH RIVETED HINGES ARE WORSE, THOSE PLASTIC FAKE HINGES. ONE MUST LOOK CAREFULLY TO KNOW THAT.

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.

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.

What EXACTLY does it do when you turn the key? This will give clues as to where the problem could be. A slow sluggish crank suggests a low battery charge or an old weak battery. In general any battery over 5 years old is considered 'Old' especially if the vehicle is used a lot. Just spinning could be a Spark issue and spinning, catching and immediately stalling out could be a fuel supply problem. Comment below with more information and I'll try to help you more.

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?

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:

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.

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.

Help here. It is the same for any vehicle.

well the service manual covers both. dcc means ( normal phantom drains, all computer that need and have memory this is memory power) the car is shipped with no DCC fuse. dome light well try it , in drive way then around the block. be brave or buy the book. the dome lamp that does no glow is not draining any batter ever sure bad door switches sure, my cars all have, dome disable switch covered fully in the users guide, (lost that?) lots of things can do the phantom drain even a bad alternator the drain is on DCC or is on the fuses marked hot all the time , vast things on that too. best is use an ammeter and not guess key off battery cable amps below 0.050amps or 50mA if above that much that is called a phantom drain then we pull all fuses, 1 by 1 to see if current falls to spec sure DDC sure dome and gee 25 more use on bat + hot all time bus. when found the same book tells you all things on that fuse even 10 or 20 things that must be pulled to prove they are not bad. not guessing or be wrong 25 + times. or more. learn to use an ammeter or pay those that do. toss coin.

no their not

To remove the glove compartment on a 2007 Lexus LS460, you will need to first open the compartment. Then, you will need to locate the mounting screws that hold the compartment in place. These screws are usually located on the sides or bottom of the compartment. Once you have found the screws, use a screwdriver to remove them. After the screws have been removed, the glove compartment should be able to be gently pulled away from the dashboard. If the compartment is stuck, you may need to carefully pry it away using a flat tool like a screwdriver or a trim panel tool. Be careful not to damage the dashboard or the glove compartment as you remove it. Once the glove compartment has been removed, you can access the area behind it for maintenance or repair.
