Jag x type diagnostic trouble shooting code P1638 and p1699

i think you can but you should check with your jag dealer to be sure, it will also need programming to the car using jag diagnostic equipment, because it is a module on the can network and the pats security system will not recognise it as belonging to the car and wont allow you to start the engine. hope this answers your question. cheers.

Does it need a radio code?

Your owners manual may tell you, or
call a dealer & ask

if its the original fitted radio contact jag agent with your chassis number found in your log book if its not the original contact radio manufacturer

What is the fault code in the transmission control modules memory, if the light is on the code must be read with a special scan tool through the vehicles diagnostic service port.

Remove negative battery cable and key out.
Remove the ECU cable from ECM. Inspect and clean all contacts with 70% alcohol.
Allow 15 minutes of dry time before reconnect everything.

Hopeful the cleaning will clear the ECU to CAM bus communication disruption.

you will have to go to jag dealer or find someone with compatible diagnostic equipment sonds like you fob has lost its rolling code or gone faulty

Hi, are you able to drive the vehicle until it gets hot, or do you sit there and wait for the engine temp' to come up to the hot setting before you can select gear ? I suggest a Jag technician or auto sparky scan the computor for DTC's, or diagnostic trouble codes, they will enable a speedy resolution to your problem.

This problem is normally associated with a failure of an ecu/can bus output, in many instances it is also associated with anouther problem being present, Air Con not operating correctly is a favorite. The best bet is to narrow the problem down try and locate what else isn't working and this will guide you to the cause problem. Problems can be anything from a faulty ECU to a blown fuse.

Simple contact you local Jag dealership and ask them, they will need the VIN No and there is a small charge. Then follow the instructions on http://www.bluejag.co.uk to enter code.

I have the same exact car and when I had to replace my battery I had to reset radio code also. Fortunately, I have the code card, but I didn't know that at first and I typed in a random code, and then it kind of "froze" it saying Searching for code or something to that sort. I called a Jag 800 number (any Jag 800 should be fine) and they told me the steps and my code, you will probably need a VIN #.
