Jaguar Repair Problems? Ask a Jaguar Repairs Expert.
The cause of your concern is that P1609 Dtc which usually indicates a failed ECM. I recommend we check all the fuses in the front engine compartment fuse box for voltage with the ignition on with a digital multimeter. The reason we need to check voltage is to also check the ECM and system.power relays and diodes. Let me know. The problem is if a new or used ECM is installed it must be programmed otherwise the vehicle will not start.
Just checking in to see if you needed any further assitance. The question is still open on my end since it has yet to be rated. If you are satisfied please rate with a positive rating so I can receive credit. Thanks.
