I don't but here's the thing to keep in mind. Brutal repairs cars for a living and he's a certified tech. Most of his tools will be high end. If it was a charger he was using, it was probably far more HP than you need.

You want 13.8 vdc
low noise
at least 50 amps

You'll be fine. You don't need to drop $400 on one. I paid $135 for mine new on eBay but the guy isn't selling them anymore. You should be able to find the model I pointed out above for around $150 new shipped.

You also always want to keep your laptop plugged in while working with SDD.

 

I found a PSC-550 on ebay, am now waiting for it to arrive. When I get it how should I proceed, since my SDD can't communicate with the ECM? In other words, what should I do first?

Can your SDD see anything?

https://www.jaguarforums.com/forum/x...ng-ecu-139181/

Look at post #10 in the above thread.

If you cannot see anything then obviously it will not work.

 

Yes it can, if I manually input the VIN. It just doesn't communicate with the ECM. I have read the post you mentioned, but could not determine where to start first.

 

Hopefully someone with more knowledge than me of SDD will chime in!

 

So it's communicating with everything but the ECU? Hopefully you haven't bricked it.

Have you tried a hard reset? Disconnect the two battery cables from the battery and then touch them together. Reconnect the positive cable to the battery. Let it sit for 10 minutes, then reconnect the negative terminal.

Now reconnect your VCM and see if the software sees the ECM.

Again, No internet connection, no antivirus software running, Laptop plugged in (basically dedicate all of your cpu/ memory, to the VCM), battery power supply plugged in and set to 13.8 VDC.

 

So what specifically is happening when you connect to the OBDII? I don't understand what you mean by it doesn't communicate with the ECM.

Are you saying you connect, it recognizes your vehicle, you go to reconfigure your modules, select "Generic Electronic Module" per post 10 in the link Jack sent you and you get a message that says communication with ECU failed?

 

Yes everything is communicating except the ECM. I'll try what you suggest and report back..

 

OK, then yes if you do a hard reset and that doesn't get the vehicle to recognize the ECM, you'll probably need a trip to the dealer per Moscow Leaper's comments in the post Jack provided.

You'll need them to connect VCM to it (Jaguars approved hardware/ software.

Let us know please and good luck.

 

Ok. thanks

 

Any luck Joe?

 

No yet, I'm still waiting for the power supply I ordered to arrive. I should have it in a day or two. I will report back after that.. Thanks for asking..

 

When I worked at the Jaguar dealer we did not have a regulated power supply. Up until 2006 we were instructed by Jaguar Tech line to use a battery charger to keep the battery between 13 and 14 volts with the key ON.

If the battery voltage dropped and caused problems like this post describes, we were NOT paid by Jaguar and any subsequent damage was ON US (the dealer). No warranty claim accepted.

Later Jaguar wanted a regulated power source and we had to purchase and use that.

A common sense approach would be to AT LEAST use a battery charger capable of 50 amps. It might not be 'low-noise' or as clean as a proper unit but it is better than a 'low-voltage' module failure.

We performed hundreds of configurations and key programming with just a simple battery charger set to low. A volt meter confirmed about 13.5 Volts so we just carried on.

The expensive PROPER TOOLS are preferred but are not always available. We did not have them at the dealer so we used what we had until Jaguar issued a specific battery power source.

The newer the cars, the more need for a proper regulated power source. We got by on what we had (Jaguar issued MIDTRONIX Battery charger/tester with printer)) for the X300, X308, X100 X200 X202, X350 and X400.

The point is...................... Use what you have. Just DON'T let the voltage drop.

Thanks, but I've already purchased the PSC-550. I got it for less than $100, so I figure it's a good deal and will provide a little extra security. In your experience, what's the chance of recovering the ECM, after a low voltage failure?

 

Thank you Bob for this info.
On one hand it's shocking from Jaguar (to leave such responsibility to the dealer, not having an approved process), and on the other hand it's very interesting as it would confirm that a low noise power supply is not mandatory but high voltage is a must.
(at least for the earlier models with a less sensitive electronics)

 

I have not personally had a low voltage failure so I never had to recover. I guess our dealer shop was lucky that we all followed the Jaguar Tech Line advise and used a battery charger.

We did have an issue with a TCM that would not configure, But Jaguar sent a GENRAD handheld device (Similar to a GENRAD 510) and we followed the instructions to get it into 'learning-mode' and sent the handheld back to Jaguar.

Thanks, hopefully I can sort this out without involving the dealership.

 

Wasn't there just a thread about this exact problem on the S-Type form a few weeks ago????

CAMBO offered several posts about how to resolve and the dealer was hesitant to employ any procedure they were not comfortable with. I think the poster (customer) provided the info and the dealer finally agreed to try.

I think it all worked out in the end.

I will try to find that post. Thanks
