Maintenance reqd light on - 2003 Acura 3.2TL

The maintenance required light just means that some sort of scheduled maintenance needs to be done. Most of the time it just means you need an oil/filter change. Your owner's manual will list what maintenance is required based on your milage. This light is not the same as the Check Engine light which means that something is wrong with the emissions system.

You usually need to have the vehicle taken to the dealership so they can perforn the required maintenence. The light being on doesnt mean that there is a problem with anything, it means that the computer knows how many miles are on the car in relation to the manufacturers maintenence schedule. If you absolutely believe you have fixed the problem you can attempt to turn the light off by disconnecting the negative battery cable for 10-15 minutes so the capasitors can discharge. If the computer determines that the maintenence item is not taken care of it will turn the light back on and you will need to take it to Toyota. I hope this helps you, if so would you please mark as solved and leave a rating?

Thank you!

Hello, and welcome to FixYa.

The 'Maint Reqd' light indicates that you are due for an oil change. It will blink 4,500 miles since the light was reset at your last oil change, and stay on steady after 5,000 miles.

If you recently had an oil change, all you need to do is reset your maintenance reqd lamp. The procedure is here on this site inthe 'tips and tricks' section, and it is also in your owner's manual.

If the dealer/mechanic did the service early the light will come on when service is DUE. Go back to him and have it turned off. Search the web someone may have the procedure posted. Usually simple. Google "Toyota service light reset" or "Toyota Maintence light reset" Try this one

1. With the car started (ignition on), set the LCD odometer readout to total mileage (not trip A or B).
2. Turn the car off (ignition key to the OFF position).
3. Push in AND HOLD the button/knob that switches the odometer
4. Turn key to ON position without starting the car. You will notice the maintenance light blink and go out.
5. Release the odometer button/knob.
6. Turn key to OFF position.
7. That's it! The "MAINT REQD" light has been reset to warn you to change your oil in another 5,000 or 7,500 miles or so.

It depends on what the trouble code is. Some codes are minor problems while others are major.

Your car has the OBD II on board diagnostic system. Take the car to an auto supply dealer and ask them to read the trouble code. (Most places do this for no charge.) They can then tell you what the problem is and likely give you information about the fix for it.

First check you tire pressures. Inflate to door sticker pressures. That should put a couple of them out

Revised procedure (for Highlander)

Turn ignition key to 'ON' and press the odometer button until the display reads actual mileage... not Trip A or B.

Turn ignition key to OFF.

Hold in the same button you used in step 1.

While holding the button in, turn ignition key to 'ON'.

The 'Maint Reqd' light should blink and go out.

you could go to a big auto parts, have the light reset
if it come back on you need to take,it to the dealer.
for schedule maintenance, 5,000 km apart from each
oil change .

It means: (Maintenance Required) get your owner's manual and match ur milage to what your owner's manuel's service requirements recomend..
