The code means the engine control module imobilisation function is active.
can you describe what the car is doing and after you scanned the code did you try to reset it?
If so and there is no difference it may be a dealer reset only and you may have a bad ecu (water ingress?)

P1621


Trouble code P1621 means: Engine control module engine immobilization input circuit malfunction The Transmission Control Module (TCM) contains various types of memory to gather and share information internally. At shut down, the TCM stores information in memory to prepare for the next ignition cycle. When the TCM cannot communicate internally, DTC P1621 sets. DTC P1621 is a type A DTC.

DTC PARAMETERS
DTC P1621 will set if the TCM cannot communicate internally for a proper shut down.

DIAGNOSTIC AIDS
The suggested repair is TCM replacement. Remember to program the replacement TCM with the correct software and calibration.
however Ive know loose positive battery cable to toss out that code, so check your connections

Wiring of coil packs


I recently, April 12, purchased a 95 XJ12 that looks like it has minor problems. Its overheating. The Jag has been sitting for 2 years in a garage. It did not have a current title or local state plates, so it was sitting in the garage.

Anyway, I am restoring it. The prev owner gave me a Jag XJ12 DVD with all the manuals and diagrams. However, it did not have the diagrams I needed for the relays. So, I started to look for manuals. Nothing exists aside from the Jaguar OEM DVD and more expensive dealer paper manuals.

Unfortunetly, the 95 XJ12 has the OBD-1 system on it. I am in the process of finding a OBD-1 for the 95 XJ12. So far, none, but am calling OBD scanner companies.

The site below cost $17 one year and $50 5 years but it has all of the diagrams for all the relays, etc, repair instructions, ...

I purchased $50 plan since I plan to keep the JAG. I think its going to be a classic.

I would like to keep in touch with you to share info on self-repair tips.

If you want to split the cost for the site above email me.

Air to fuel issues


This could come from your ECU, your gas line or who knows what. There are so many parts in jags its almost impossible to find the exact problem, which is why the **** at Jag have to decided to completely replace things instead of trying to fix them. Good Luck.
