My tester shows faulty seat track positioning sensor, but my seat works. Do you know what this could be?

Hi,

The seat track position sensor isn't related to the operation of the seat movement. Instead, it is used by the Occupant Restraint Controller (ORC). The ORC uses the information (positioning of the seat) in determining the appropriate deployment force to be used when deploying the front airbags.

I'm not sure what code you have, but this is something that should be replaced. It is not repairable or adjusted. Now, the sensor could be bad, or it could be related to a wiring issue in the can-bus system. CAN stands for controller area network. Basically, the computers and modules are tied together via a few wires, so they all communicate together.

I hope that makes sense. Let me know if you have additional questions related to the sensor.

As far as the issue, first inspect it to make sure the wire to it is not damaged, broken, or disconnected. See pic 1 for location.

If you look through the remaining directions, they are for the removal and replacement of the sensor. Please note the warning in pic 2 and the last pic. The last pic indicates the need for a scan tool.

Let me know if you have questions or if there is anything I can do to help.

Also, when checking the wiring to the sensor, here is a link you may find helpful:

Take care,

Can you send me a photo of the sensor? So, I know for sure what I’m looking at. Thanks

Absolutely. If you look at the pic below, it shows the sensor. My manual doesn't offer that pic, so I had to find one online.

I hope that helps. Let me know if you have other questions.

Take care,

Joe

Do I have to use a scan tool? And if so which one do I need and how do I use it.

And would it be dangerous if I just unplugged it for now? Something is draining my battery and I think that might be the reason.

Hi,

If the battery is being drained, it won't hurt to disconnect the sensor to see if that is the cause.

As far as the scanner, it will require an upper-end scan tool that can communicate with multiple modules. I attached the directions for the supplementary restraint's verification test.

Let me know if this helps.

Do I just unplug the sensor, or do I need to disconnect battery first?

If everything is turned off (ignition), you should be able to just disconnect the sensor.

Let me know if that takes care of the battery draw.

Take care,

Joe
