Can I ask if all of these codes came up at once? If not, please start a new question for each code as we only handle one problem per thread. If they came up all at once I would try a hard system reboot or the software needs to be updated.

Here is a guide to help with the reboot:

Because these codes are different systems but still networked through the CAN I am leaning toward the software update. Please check all fuses in the car before we begin the repairs. Please go over this guide and get back to us.

No, they didn’t come up at once. I first had the ABS and airbag codes. Now I have the engine error code for the sensor.

I will check the fuse and start a thread for each code.

Thanks

Sounds good, if all the codes came up at once then we would have something in the CAN or computer issue.
