Hi, I have two scanner, John Deere EDL v2 and Nexiq usb link. EDL connection with service advisor is perfect. But with usb link, it doesn’t work. The only way where i have connection with usb link is in GetEcuId.
But finally I got Nexiq usb link to work with Service Advisor software
Here is how to operate…
First, you must reflash your Nexiq with John Deere EDL firmware. When you do that, you\ll got EDL as connected device in device manager.
Find original firmware and save it (backup)
In John Deere Service Advisor find EDL.bin
I do not remember where it location …
Copy and rename EDL.bin to usblink.bin
replace original C:\NEXIQ\RP1210A\usblink.bin
Go to C:\NEXIQ\Test
check checkbox – Enable automatic USB-Link firmware update
firmware will be update
and Nexiq name will be changed – now EDL-Link
Please take a note, that firmware reflash is possible only with original nexiq or HQ nexiq clone, LQ clones can’t be reflashed, even with newer nexiq firmware
It depends on what clone you have, my clone get all updates,works with OBD volvo,and have no issue.
Second, you must modify standard heavy duty diagnostic scanner Nexiq 9 pin deutsch cable. just simply revert positions of CAN lines. There is two pairs of CAN lines. Here is instruction and picture how to do that here
