Need help with check engine light on 1995 XJS
I started my 1995 XJS with the AJ16 motor and the check engine light is staying on. The engine starts fine and seems to run fine but my OBD2 scanner does not seem to communicate with the system.
I do have the OBD2 plug in port down under the dash next to the hood release lever and my OBD2 scanner plugs into this port but again does not seem to want to communicate with the system. Any chance my scanner will not communicate with this car for some reason or is it possible I have a blown fuse etc tied into this system? Any insight or feed back on this would be greatly appreciated. |
You might have an OBD-1 port.

Well what kind of code reader are you using?

I have a CEN-TECH CAN OBDII CODE SCANNER. Says it works with all OBDII Compliant Vehicles Sold in the U.S. Since 1996. As I stated it does plug into the port so am I correct in assuming that a OBD2 scanner will plug into a OBD-1 port? Someone had told me that the OBD-1 port is different and will not allow the OBD2 scanner to plug into it but I am thinking that is not correct.

The obd 1 and 2 ports are physicaly the same but the protocols were not standardized until obd2.
You may be able to see if some of the obd2 pins are not present. Then for sure it is still OBD1 Jan 1 1996 was when OBD2 was mandated. http://www.obdii.com/connector.html#dates |
