Mazda 6 reset after battery change

The Mazda 6's engine light is designed to quickly alert the driver to failing drivetrain components. When the light comes on without reason, or refuses to turn off after the problem has been repaired, a manual reset is required.

Since the light is controlled by the computer system, momentarily disconnecting the power supply will turn the light off, delete all stored error codes, and restore the system to a factory state. Place the socket wrench over the nut on the negative battery cable and loosen it only until the cable is free to slide off.

Do not fully remove the nut. Move the cable as far away from the battery as possible, to prevent it from springing back into place. Turn the Mazda's headlights on.

This will help to more quickly drain power from the computer. Wait 5 minutes, then turn the lights off. Reconnect the battery cable, securely tightening the nut. Start the engine and check the dash to confirm the light has been reset.

If you can't find it, call Mazda and they will give you the code for free.

Q: Battery change. Do you do computer reset after battery change?

This is a long story with a lot of details, sorry. We have a Mazda3 with 87k miles on it and my husband left the lights on while we were at a fair for four hours. We realize now after doing research that this was a stupid thing to do and batteries should never cost that much to replace, but we didn't know at the time and we trusted the guy because he was sent by our insurance company.

I thought the whole thing seemed a little fishy when I saw that he had a ton of batteries in his trunk. We just really wanted to get home and didn't question it at the time. We started the car and proceeded to leave. There's a one way gravel path through the woods to leave the fairgrounds with a lot of little hills and no shoulder. Other cars were leaving too so we were in a line of them. Just then, I noticed the air conditioner was putting out hot air and my husband said the brakes weren't working.

He had to use the emergency brake all the way to the main road where we could actually pull over. Then we noticed that a bunch of different warning lights were on, including the check engine light.

The time, trip monitor, and radio stations were all reset, but we weren't surprised by that. We called the guy who installed the battery and he came back to check on us. When we started the car again, it was functioning normally.

We are taking it to the Mazda dealership tomorrow, but I don't think I can trust them either.

The PCM will trigger the indicator light to illuminate to inform you there may be an issue with your Mazda. Occasionally, the information remains stored with your PCM, even after the issue has been fixed, and your indicator light may remain on until the PCM has been reset.
