Renix is Renault bendix injection. Obd 1 and 2 are newer computers with on board diagnostics. Just different types of computers basically.

If you have a '93 you have OBD I which flashes a light to inidcate electronic faults. OBD II has a port to plug a scanner tool into, and was on the '96 and newer XJs.

Your 93 would be OBD1

RENIX is 87-90
OBD1 is 91-95
OBD2 is 96-01

Here's how to read the diagnostic trouble codes on OBD1 & OBD2:

Being new to the internet, you should know that search engines are one of your best tools.
For example: Here's a google search for renix vs obd1 vs obd2

...and welcome to the forum.
