For a 2002 Toyota Camry, what fuse is for the check engine light? There are 3 ECU fuses - ECU-B, ECU-ACC and ECU-IG ( all info states to check the ECU fuse) - thanks

SOURCE: 1989 Toyota Camry. No brake lights.

It could be the relay, which is a yellow box located under the carpeting in the trunk on the left side. It is a problem common to your model. Also, check the brake switch's (behind the brake pedal) functionality (12V present with key at ACC or ON and continuity between wires when button engaged).

i hope this helps

Testimonial: "Wow! I would have never found the problem without you guys. It was the relay located in the trunk. Thanks!"

anyone knows the solution for Camry Engine code 440. I reset at half tank of gas & then filled upo the tank. Engine Light came back exactly on half tank again.

Sounds like a condenser or noise filter. the ECU-IG fuse powers the main relay. I think you would be better served tpo take it to the Toyota dealer or a shop that does Toyota work.

[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:
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."

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.
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.]

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?
