  5. Select OBD-II, then READ CODES.  Make sure there are no current fault codes.  If any codes show up on the scanner, they must have PAST or STORED status, not CURRENT.
  6. Go back and select CLEAR FAULT CODES.  Press enter. 
  7. Turn off the ignition, wait 10 seconds, and restart the engine. Check engine light should be off. 

Check Engine means you have a problem that should be diagnosed and corrected as soon as possible. Do not clear the fault codes without fixing the underlying problem. Doing so could lead to more damage and a higher repair cost.

How to Reset the Toyota Maintenance Reminder

Toyota Maintenance Required

Maintenance Required means you need an oil and oil filter change, air filter change, fluid check, and other checks and changes depending on mileage. These are listed in your owner’s manual.

First, perform the recommended maintenance.

Here’s how to turn off the Maintenance Required light.

  1. Turn the key so the car is on.
  2. Make sure the odometer is displayed, not trip A or trip B.
  3. Turn the key so the car is off.
  4. Push and hold the reset button on the trip meter.
  5. Turn the key back on again, but not to the start position.
  6. The odometer will display dashes that disappear one at a time, and then a set of zeros will appear.
  7. Keep holding the button down until the zeros go away and the odometer reading comes back.

The appropriate maintenance should be done to ensure a long engine life.

Instructions for resetting Toyota check engine light work on all 1996 models, including Toyota Corolla, Camry, 4Runner, Rav4, Matrix, etc.

Frequently Asked Questions

Why does the Toyota check engine light comes back on after I clear the codes? 

  • If the Toyota check engine light doesn’t turn off, it is a problem that has not been fixed yet. Reread the codes and fix any present codes. 

Can I clear the codes without fixing the problem? 

  • Clearing Toyota fault codes without fixing the problem is not recommended. The check engine light will come back on immediately or within a few, depending on the issue. 

Will the Toyota check engine light reset itself? 

  • If the underlying problem is fixed, the check engine light will reset itself. Check engine light won't reset as soon as the problem is fixed. It may take up to four days of regular operation for the Toyota check engine light to reset on its own. 

Can I reset the Toyota check engine light by disconnecting the battery? 

  • It is possible to reset the Toyota check engine light by disconnecting the battery, but this method is not recommended. It does not fix the problem, and the light will turn back on.

This does not work on a 2002 Toyota Corolla. The OBD port is under the hood. I cannot get my OBD2 tool to read this car with the adaptor.
