Great video! I really appreciate your thorough explanation of the system.

I like your videos and how you keep it simple. I am trying to brush up on my diesel knowledge and I find your videos very helpful. I completely forgot about how the smart charging system works with the IAT to regulate system charge, this is something that tends to be overlooked in making diagnosis (at least by me, lol). LIN Bus is also important and somewhat different to pinpoint possible causes of failure, but a scope is certainly a must have for accurate TESTING. Nonetheless, it is a great reminder of the various variables that must be considered when attempting to diagnose these systems. Thank you for sharing your knowledge with us sir.

Thanks for this information, I am getting more and more knowledgeable on my defender puma,✌️ top man

top info dude as ever!

very informative video.thanx

....good stuff mate.....it's bloody stupid how complex these systems are becoming though....you'l soon need a degree in electronics to change a light bulb...

👍🏻

Puma 2.4 has two wires, what is the use for these two ? is there also LIN signal? These are named D+ and ALTMON

Hi, Ive got a question about the voltage Level. Meassuring the voltage directly at the battery i get values around 14.8V. The temperature outside is below 5 degrees. Is the value to high? I was expecting maximum 14.4V . (2.2L mj2012 defender)
