What is the Authorized Software Update label on my engine computer?
Share
It’s a label a Chrysler dealer puts on an engine computer after reflashing it with newer software, usually during a recall or a service bulletin repair. It carries a new part number for the software that’s now in the computer.
That number replaces the one on the original label. When you order a replacement, use the number on the Authorized Software Update label, not the original one.
Where to find it
It’s usually on top of the computer, next to the original label or stuck over it. On some larger 4-plug computers it’s on the narrow end of the case. Our Find your part number page has photos of each spot.
Reading the number
The number is often printed in two sizes: a small first half and a big second half. On an update label that reads 56040 in small print and 197AC in big print, the part number is 56040197AC. Type it just as it’s printed, with or without the P in front and the letters on the end.
