OBD1 vehicles


The pre-OBD2 1993-1994 XJS and XJ40 can sometimes be difficult to diagnose without the old PDU tool.

We have a simple workaround for reading the ABS and TCM in those 1993-1994 models, as the same modules were used in the later OBD2 compliant vehicles.

With this adaptor cable, you can plug into the diagnostic socket in the boot/trunk and read/clear ABS and TCM fault codes using the 1995 XJS protocol.
