Does the XK8 or XKR (X100) have an event data recorder, EDR, flight data recorder or black box?

 

Only 4.2 liter (2003MY>)

Well, there is also a blue Box, the Airbag module, that will register some data as well.

 

Event Data Recorders (EDR), aka "Flight Data Recorders," aka "Black Boxes" in automobiles have been around (in the USA) since 1990. Early recorded data recorded was limited but included speed and seat belt use, which greatly aided both law enforcement and manufacturers in accident investigations. In 2014, the Feds mandated that every new recorder must track at least 15 variables, including vehicle speed, throttle position, airbag deployment times, whether the brakes were applied, if seatbelts were worn, engine speed, steering angles and more. Recorded time is about 20 seconds, and loops continuously until the inertia switch senses an accident and activates.

Manufacturers may also have up to 30 additional data points if they want, (excluding GPS location, video and/or audio). I would imagine that any Jaguar with an ECU/ECM and any amount of non-volatile memory records data for accidents as well as standard operational considerations.

 

Thank you for the replies.
Two motives, (1) trying to understand what someone did while driving my car and (2) figuring out how to get it back on the road after a tail first, trunk deep, dip in a marsh.
From what Redline said, is there at least a speed recorded somewhere? In the ECM? If so would a tripping of the inertia switch would be required to store the data? (no airbag deployment).
Where would the inertia switch be located on a 2001 XKR?
If I briefly connect the battery the fuel pumps can be heard. (as well as doors locking and unlocking, random seat movement and windows that won't move). Are the fuel pumps indicative of the inertia switch not being tripped or water in the relays? My thinking is that if the inertia switch has tripped then there may be data to find. if the switch requires a manual reset then locating the switch an noting if it resets would be a good first step. Unless of course nothing is retained prior to model year 2003 as Bob indicated.
So sad.., fresh water from the top of trunk relays to the bottom of the brake pedal. (rear-end was downslope) Aside from the water, not a scratch.

 

If the inertia switch tripped, there should be some information data recorded, and a probable "P1582" code stored. Most OBDII readers would show the code, but it would take the dealer SDD software to read/erase the code & data.

Shamelessly borrowed from another Forum referencing a 2003 XJ:
"P1582" Flight recorder data stored
This code is generated by one of the following issues
1) Inertia switch activated
2)Throttle failure causes default limp home mode
3)Engine starts and stumbles
4)Engine fails to start
5)engine stall (Apparently this code is generated if you let go of the key before the car starts as it logs it as a failure to start.)

Look inside the fuse box at the left side of the dash; the inertia switch should be in there. From JagRepair.com:

 

The ECM did not get wet, but unable to connect through OBD port. Thought if I could find the inertia switch then I would know if worth the effort to send in ECM for data retrieval... if any. Any idea where the inertia switch is? Also Motorcarman Bob or Avos, please weigh in if there could be anything found to begin with since this is a 2001MY.
As for getting back on the road. If the water line was from the top of the battery to the bottom of the gas pedal, I am thinking seat modules and trunk relays are the affected components I can think of of the top of my head. Any insight as to hidden electronics in that wet area I should look for?
Thank you

 

I was incorrect when I stated 2003MY>.
The EDR started with the introduction of the AJ27 ECM.
There should be 37 frames of data logged in the ECM in either or BOTH channels (A or B).

Am I correct that this data has to be decoded by Jaguar?

 

Any scan tool capable of getting into the SETUP and CONFIGURATION tab can read the EDR info. You can read/print the 37 frames of info and the START TIME RELIABILITY info.

WDS, IDS (or other diagnostic devices?) can access the data.

Thanks for your help and answers Bob.
I cant seem to connect to the ECM but could prior to this event.
If My ECM was some how damaged by water, I assume with proper programming I could use a replacement. (several on E-Bay)
Assuming the anti-theft security code and other data is not retrievable, is the dealership the only one who can program a replacement unit? Any Idea as to costs of said programming?

 

Have you inspected and dried out all the wet electronics already? Check the electrical manual for the location of the various control modules. I believe at least the SLM is in the trunk. The seat control modules are pretty low, too. All of that needs to be cleaned and dried out. Remember, all these modules are connected to at least one data bus, and any one bad module can, in principle, prevent that bus from working at all, hence your inability to get diagnostics, even if the ECM remained dry the whole time.

Taking a step back, there are probably resources online that explain steps to restore a flooded car, and for electronics in particular...

 

Reset Inertia switch and was then able to connect. No P1582 however.

 

Key with wet electronics is to remove them from power as soon as possible,
It will at least stop electrolysis and reduce further corrosion.

If it was truly clean water, you may get away with simply opening up the module(s) and allowing to dry out.
