On most modern cars, they have what's called an occupant detection system and that what that does is when there's a passenger in the passenger seat, it'll either have the airbag turn on or turn off in a collision.
So if there's no passenger in the seat, the airbag won't go off and you won't have to replace that air bag module.
When you replace any part of the system, though, you do have to do some calibrations and some resets.
For example, on this Hyundai right here, if you replace any part of the seat, you have to actually reset the system and recalibrate it.
Let's walk through that right now on this car. The tool is hooked to the car and the ignition is on so let's power up the tool. We're going to select our Scanner function. The beep means it's already automatically identified our car for us so it's going go through the automatic ID process.
There's the vehicle, click okay, and it comes up with a list of systems. Occupant Detection System is what we are looking for.
And then you see we've got Codes and PODS Reset, which is going to be the function we're going to use here.
It says PODS comes from the Passive Occupancy Detection System. This function is used for initialization of the PODS ECU. It's currently a vented and heated seat. It says we're going to use the PODS Reset when the front passenger seat is empty, so we want to make sure there's nothing in it.
If the reset fails, carry out the steps below. You're going to double check, make sure there's nothing in it, and also cycle the key if you have to reset it again.
So we're just going to go Continue here and then select the reset mode in the next step. You're going to choose the auto mode when you're replacing the seat assembly or the seat foam, and then you choose manual mode when you're replacing the ECU itself.
We're just going to go through as if we had replaced some seat components so we want to do auto mode.
It's going to say it's doing the tests. It's going to re-zero the seat and estimate what weight is in there.
It says the reset is complete so we should check for any codes in the system. We'll just go through here and double check the codes real quick. No codes are present, the job is done and the seat is reset.
