This fault also happens with my 2nd fob.
I'm seeing a resistance of 11 ohms across the coil. Of the 2 wires connected to the coil, with car immobilized I'm seeing 0v on the yellow/brown wire and 11.5v on the red/green wire. This situation doesn't change when I disarm the immobiliser with the fob. 've not done anything to either fob apart from changing the batteries. It's beginning to look like a fault with the SCU? It's a Pectron unit.

regards
Jon
