I READ ONLINE THAT THERE WAS A RECALL ON THIS YEAR AND MAKE, CHECK WITH TOYOTA WEB SITES TO RECTIFY YOUR PROBLEM
SOURCE: i only have high beam headlights
about troubleshooting your headlights on your vehicle. I would isolate the wire that comes from the headlight switch to the headlamp bulbs for low beam and check to see if there is a short in the wire. You can find this wire by using a test light turn on the key and get a good ground with the test light poke the wire and see if the test light illuminates with the headlight switch on.
----
Also check the wires, and check the fuse for your low beams. could of blown a fuse on your lows, but your highs will still work.
Every single time I have had a failure of low beam in a headlight without failure of high beam, it has been because the lamp bulb or halogen lamp module has reached the end of its serviceable life, not because of any wiring problems. Low beam burns out first because it is on the most. If low beam is lost simultaneously in both headlights, I would check fuse first, then the headlight switch. If low beam is lost on one side only, it is almost always going to be due to the bulb or lamp module needing to be replaced. In that case, replace them in both headlights because the other one will be going kaput in short order, as well.
There is something to check. Does the low beam relay click when you turnt he low beams on?
if it does not click then
Then find the BCM at the base of the steering column. In there find the grey connector and in there, find the pink/white wire in terminal A4. Use a wire to jump that wire to ground. IF the low beams come on, then it is likely the BCM is bad.
Also check a bad wire between the fuse block and the BCM. before replacing the BCM . Start under the fuse block. This is the fuse block under the hood.
This will
help. Thanks please keep
updated.please do rate the solution positively .thank you for using fixya

For the I6 engine there is a relay for low beams, it's relay # 46. Switch it with relay #45 (runs the fan, same model relay) and see if your lights now come on. These 2 relays are the only 2 black ones in there (part # 15016745). Also, try to clean the contacts very well on the fuse box and the relay. If not, you may have some frayed wiring in the harness.
By the way, the high beam relay is #43, the gray one next to the windshield wiper relay #42.

[Information] For a 2002 Toyota Camry, the Daytime
Running Lights (DRL) operate utilizing the High Beams (inner Lamps closer to
the center of the vehicle front) at a reduced power. [The troubleshooting process:] Review the Owner's Manual and ensure the test
configuration matches the following criteria: 2. Set the Test Conditions according to Step 1 above. 3. Check the headlight bulbs to ensure they are not
burned out. If one burns out, there is a fair chance that the other would have burned
out at the same time. Replace as necessary.
In this case, if the high beams operate, the DRLs should also operate. My problem was that the test configuration did not have
the engine running and parking brake off - Step 1. Problem solved with much
thought, repetitive tests on the vehicle and going back to the basics -- what
does the Owner's Manual say and where are the applicable fuses and relays
located?
1. According to the 2002 Toyota Camry Owner's Manual (Check your Owners Manual):
"The DRL system will make your headlights come on at a reduced brightness
when:
The light switch s in the "DRL" position.
The ignition is on with the engine running.
The headlight switch is off.
The parking brake is released."
4. Test the system, ensuring the step 1 conditions are set. (Engine running, Multi-function
Switch on Turn Signals in "DRL" position, headlight switch off
(repeating what the manual says -- it should be obvious that in the
"DRL" position, the headlight switch should be off / do not have the
switch positioned to "High Beam"), and the Parking Brake
"off").
5. If DRL lights do not work, check the engine compartment Fuse and Relay Box.
there is a 5 Amp DRL fuse -- replace it with the spare. Test (step 4).
6. If it does not work, swap around or replace relays -- there are three (3).
Any one of them could be bad (stuck or burned out). Test (step 4).
7. Other less likely possible issues
could be that the Multi-function Switch is broken or a connection / wire is
broken. [Beyond the scope of this
process.]
