Anyone know what would cause the ecu to activate its 'self shutdown'.

I have traced my current problem to a pin on the ecu that is described as 'self shutdown'. This pin should (in normal use) be 12v. It supplies the main relay with it's 12v switch. It is currently reading 9.97v, so not enough to activate the main relay.

Any ideas?

Too scared to look, cant have two engines in the same year, praying its electronic.......

I dont think cambelt snapping would effect ecu in this way though??

I dunno about electronics as you know mike, but, 'if' the belt went, could the sensors reading their respective signals and the fact that they'd be out of sync not make the ecu shutdown as a safety measure.....

Maybe????
