ECM Not Communicating With SDD - RESOLVED
#1
![Default](/forum/images/icons/icon1.gif)
I'm sure this has been answered somewhere in this forum, but I'll ask here. I was re-flashing my 2004 xjr (X350) using Mongoose Pro (not a clone), and SDD v131.02, when the battery voltage dropped a little, now the car won't start. The SDD does not recognize the VIN and cannot communicate with the ECM. Is there a "simple" fix for this, or do I have to bite the bullet and visit the dealer? Any help is appreciated.
Thanks

You really need a battery support system as Paydase mentions.
LOTS of horror stories with people not doing that when reflashing.
This is it.

May or may not help you.

NO!
You need a specific "stabilised" power supply, with a voltage that can be set at about 13.6 Volts.
A standard battery charger, even more the intelligent battery chargers, vary the voltage during the charging cycle, so this does not fit.
There are cheap chinese stabilised power supplies for 50-100 USD on ebay that can do the job in principle, Jaguar recommends a much more expensive (ca. 400 USD) quality device capable of 60 amps, you need at least 30 amps but better take a 50 amps.
Look for threads on the issue, there are many

As you're in the US, you can have these ones, very good and cheaper than the Jag reommended one:

It looked more like a battery charger. I have used regulated supplies at work for years. This definately looked more like a charger.
Worked great, key was programmed in 20 minutes or so.
He is a Master Tech, if a charger would not be stable he would not use it.

I had a key programmed last week. Brutal had a large roll around power supply. It was big and heavy.

I got this one and it has worked good the couple of times I have had to use it. They also make a 50 amp version as well. In retrospect I should have gotten the 50 as it does, in my opinion, push the limits of the 30 amp. This is on my 2004 VDP
