2012 Hyundai elenatra code 605 could a tracker be the cause?

Question

The day after my client added a tracker to his daughter who leaves for college on Wednesday's car it threw the p605 code. Could these be related?

Answer 1

P0605 Internal control module Read only memory (ROM) error

More than likely this may not be related to what you have Hyundai has a TSB about this code condition on how to approach this from a diagnostic approach. and this code is usually not set by itself but is accompanied with another code such as P0605 and P2110 , When its P0605 and P2105 and they are the only codes present you replace the PCM. TSB # 13-FL-001 titled Engine control P0605 diagnostic procedure.

So the code came up by itself, if that makes a difference. I did see the TSB about the Elentra years 2011-2013. However, it seemed oddly coincidental that it would happen the day after he plugged a tracker into the OBD/DLC port. And that it would come up alone. I unhooked the tracker cleared the code and instructed the customer to return if the code did. I asked him as well to plug the tracker in a day before she goes to see if it immediately comes back. A little anecdotal test. But I was curious if anyone had run into this causing that code
