2015 Ducati Monster no spark after battery swap

[monstersp33d]

my cousin has a 2015 ducati monster. he’s put over 9000 trouble free miles on just threw a major fit. The previous owner had the ECU flashed, so it didn't need a chipped key, and it’s been perfect for a year.
It died last week. We swapped the old, seven year old battery, and it fired right up for three days. Then, bam! no spark again. We even tried the expensive battery from my bike, cranks like a champ, but still zero spark.

Now, the immobilizer LED is blinking and staying on. It looks like the immobilizer, which was supposed to be disabled, just woke up and bricked the bike!
He only paid $1,700 for the bike, so the ROI is great, but the official fix is $3k+ (new ECU, keys, etc.). Has anyone had an immobilizer resurrection like this? Any low cost, Hail Mary fixes before we give up on this awesome beast? Help us save the Monster!

Tough spot youre in. Unfortunately, it does happen on older systems where a complete power loss can reset or corrupt the ECU's modified memory. Cheaper option is to try re-disabling the immobilizer. Send the ECU out to a specialist who can reprogram it to delete the immobilizer function permanently. Some people have had luck by simply checking the antenna around the ignition switch or verifying all the fuses, but the flashing light staying solid points heavily toward the ECU needing another bypass operation.

If the ECU just needs a temporary "kick" to re-sync, entering the override code might allow it to start and clear the current error state.

If your cousin happens to have the original Code Card, you can try the emergency override procedure. That's the temporary fix I know of. So have him look for the code and enter the 5 digit code.
