Hello, I recently got a Mongoose cable clone and was messing around with IDS to reprogram the ABS module in my 04 XJR. It gave me a message saying something fatal then CONFIG E appeared on my dash board. Tried driving after and all seemed fine the but the message persists. Really freaking out as to what I should do now!

 

Did you have a power supply on the battery when reprogramming the module? Also, you might be screwed programming a module with a clone!

 

No power supply, but it had a new battery and I only hooked it up for 15 mins

 

Not good enough! Programming requires over 13 volts and your battery alone will not supply that.

 

No good.

You need at least a 30 amp regulated power supply on the battery when programming any module and I'll defer to my previous point, your rolling the dice configuring any module with a clone cable.

 

You could use another running vehicle, with jumper cables to supply voltage.

 

Eh, may or may not work....

 

Saw someone on the computer using another vehicle to supply voltage.
Thought with no other option for steady voltage, this should work.
But i could be wrong.

 

Thanks for the replies. In retrospect of my stupidity I am not sure how to proceed. I will not be messing around with that clone cable anymore. Shouldn't a Jag dealer be able to reset the ECU no problem to resolve this?

 

When they were current on the model they could have done it with their eyes closed. However even the techs that were there have only a vague memory of what to do. When a module fails to communicate there is a very specific time dependent procedure for bringing it back to life. A main dealer probably would not want to touch it. However many independents are still current enough to work through the procedure.
I have done it, just a DIYer, with the 131 SDD and the latest JLR VCI. Took a while before I got it right, but wasn't paying by the hour! 131 is actual Jag software, not a crack, that works since, if the date is set right, it thinks it is current.

 

Sadly no independent shops in my city have OEM dealer software. Do you have a recommendation for where to buy the JLR VCI? Also what computer were you running SDD on? Does the JLR come with software? I was virtual box on windows 11 when I messed mine up.

 

FIXED. An update on this thread. Dante brought the car to my place and we worked on it there. There were a number of issues - mainly ground problems - we dealt with before starting the main fix. The last try was programming the ECM to get rid of the config-e message. It failed and the ECM was put off line. We tried the recovery procedure and it also failed. The car was dead in the garage, it was late so Dante borrowed one of our cars and went home. Next day I went over the grounds again and cleaned up the ones at the headlights. Tried a re-program with same results.
Ran tests on CAN lines. There was a ground fault on the bus. Jumped to the ABS module since I have seen the same on two others. It had the short internally in the module. They still work with the partial short but make programming the ECM fail.
Disconnected the ABS module and jumpered the connector CAN lines. Did a reprogram on the ECM and it worked when the recovery procedure was done. Config-e was eliminated and the car was functional again.
