Another non starter

Following a 240 mile round trip I parked up and unloaded on the drive at home. On returning to move the truck the fob didn’t work and the immobiliser remained on.
The green 10as I had fitted by a local Indy after the same experience four years ago had failed.
I have purchased another green 10as and a Nanocom. The fob is now working but being new to the Nanocom I am struggling to get the immobiliser to disarm. Any suggestions appreciated

I have now found a step by step walk through of installing a green 10as on a puma on the Nanocom forums so will give it a go when the Christmas dust settles

A key thing is to resync the 10AS to the engine ECU, which the Nanocom can now do.

Yes
I spent a good few hours researching how to do this with the Nanocom last night. I’ll get to it after the festivities

The Nanocom has a function in ecu to “resynch ecu” when this is pressed the option to synch immobiliser appears and it does this immediately. No flashes or beeps.

Truck started first try after this

As I thought, a 10AS to engine ECU resync would be key.
What is worrying is that your 10AS randomly lost sync to the Engine ECU. This is not normal behaviour. I wonder if power to the 10AS was lost at some point. So worth double checking connectors and fuses are seated well.

All connections and fuses were cleaned and checked before purchasing another unit. The expired unit is from 1996 and the “new “ one is from 1995. I will split the old one and examine it for dry joints and may even have it repaired for future use. The nearly 30 years of age of the expired unit could be part of the issue and one I could be dealing with the next one
