20 Most Recent 2002 Lexus RX 300 - Page 4 Questions & Answers

If you are referring to the mag wheel puzzle lock, storage is an optional location. The RX300 has a number of storage pockets, so check the spare tire area and tool kit, then the rear storage side pockets, glove box, console sliding drawer at bottom of console and your map pockets on the doors. If the puzzle key is missing , go to the dealership. They will have a matching master set and can order a replacement after identifying yours.

Vehicles: any failing to keep its battery charged.A vehicle unable to charge its own battery has one of 4 problems:(a) alternator failure(b) voltage regulator failure(c) battery failure(d) wiring problem between battery and alternator/voltage regulator.One most modern vehicles (including 2002 Lexus RX300 - 2WD and AWD), the voltage regulator is an integral component of the alternator and is not separately serviceable.In the US, one can get a free "charging system diagnosis" from the popular auto parts chains: AutoZone, Advance Auto Parts & Pep Boys. You needn't remove any parts from the car to get this diagnostic, since they can attach a diagnostic meter to the charging system in the parking lot. This diagnostic aid will tell you exactly which component has failed - battery, alternator or voltage regulator.In case the vehicle is immobile, one can DIY (do it yourself) the diagnosis.(a) inspect the wiring for corrosion/loose connections/loose connectors/etc.(b) check alternator belt/pulley - if drive belt is properly turning the alternator pulley (no slippage/misrouting/etc.), then the mechanical tests are complete, and you'll need to continue testing the electrical performance of the charging system components.(c) first component to test: batteryDIY test 1: remove battery from car and put battery on a 120VAC automotive battery charger and charge it fully (or just check it in the car with motor off, since the car's charging system is a type of automotive battery charger).test parameter: a fully charged lead-acid automotive battery should read 12.45 volts on a VOM/DMMDIY test 2: disassemble battery out of car after driving it to one of the auto parts chain stores (Advance/AutoZone/Pep Boys) for a free battery test. These testers will test the battery under load, which is not possible with just a DMM.(d) if wiring is good, and battery tests good under load, thenthe failed component is the alternator/voltage regulator - by process of elimination.(e) DIY test 3: direct alternator/voltage regulator test (car must start and idle successfully to perform this test)Start the car, and put a VOM/DMM across the terminals of the battery. Since the car is running, you'll be reading the output voltage of the alternator and not the output voltage of the battery. The acceptable ranges for alternator/voltage regulator output are:ALTERNATOR CHARGING VOLTAGEMost alternators that are charging properly should produce a voltage of about 13.8 to 14.2 volts at idle with the lights and accessories off. Always refer to the vehicle manufacturer's specifications. Many Asian vehicles, for example, have higher charging voltages of around 15 volts.When the engine is first started, the charging voltage should rise quickly to about two volts above base battery voltage, then taper off, leveling out at the specified voltage.The exact charging voltage will vary according to the battery's state of charge, the load on the vehicle's electrical system, and temperature. The lower the temperature the higher the charging voltage, and the higher the temperature the lower the charging voltage. The "normal" charging voltage on a typical application might be 13.9 to 15.1 volts at 77 degrees F. But at 20 degrees F. below zero, the charging voltage might be 14.9 to 15.8 volts. On a hot engine on a hot day, the normal charging voltage might drop to 13.5 to 14.3 volts.Here are the full specs for installation of the 2002 Lexus RX300 alternator - you may be able to check these specs yourself (with a torque wrench), or pass them along to your mechanic.Note: the VIN 8th digit should be "F" for the 2002 Lexus RX300 (2WD & AWD)2002 Lexus RX300 (2WD and AWD) - 3.0L Engine, VIN "F" SFI DOHC Alternator Drive belt. Tension the belt to 170-180 lbs. for a new belt or 95-135 lbs. for a used belt. Adjusting alternator lockbolt. Tighten the bolt to 13 ft.-lbs. (18 Nm). Alternator pivot bolt. Tighten the bolt to 41 ft.-lbs.

Its telling you that 1 of the tail/brake lights bulbs isnt working. its logical

it is most likely the motor and the only way to check this is to remove the door panel and unplug the motor to see if it is receiving a signal from the switch.....sometimes you can try hitting on the door panel or slamming the door while someone else is working the switch......i hope that this will help you and if you need more info let me know......let me and fixya know if i was able to help you and a thumbs up and a comment would be appreciated.....thanks and good luck and have a blessed day.....

Give some more details of the problem.

Door needs opened up and the regulator assembly replaced.

the first place to start is the connector for the harness, probably under the package shelf in the trunk-look there to see if it has been accidently disloged. If not, make sure the wiring has not been damaged, lots of 'pinch' areas in the trunk-hope this helps

Access to the tail light cluster should be through panels in the rear corners of the vehicle. Remove the panel and you can remove the tail light cluster to replace the bulbs. This is the position on most sedans, unless, like on pick-ups, the tail light lenses have screws which allow the lenses to be removed to change the bulbs.

Every 90,000 miles or 72 months per manufacturers recommendations.

You need a service technician to cancel the problem codes.

You can try pulling fuse out for radio wait 1 minute or so reinstall see if radio clears up.Unfortunatly these days modern electronics can just go haywire.If dosent return to normal you have to bring to audio shop to see if its just a display problem or radio is shot.

One of a multiple solutions .Gotta have fuel /Gotta have fire.If you have both possoble broken timing belt..With a broken belt sound of engine turning over than be different than normal..Some say like a sewing machine due to no compression. Check fire at a spark plug..If you have fire have someone tap the bottom of the fuel tank with mallet while turning over..Nine times out of ten vehicle will start if fuel pump bad.May start again but not for long...Good Luck

could be a dry alternator bearing,use wd40 to confirm.
