Title: Old PC3 serial version from an earlier version (before k5) on a k8 gives fault
Post by: antman on Friday, 25 August 2017, 01:30 AM

Hello People,

I recently picked up a box of parts from a guy wrecking his bike (earlier version <k5)
Does anyone know what the difference between a k4 and k5 plus in terms of injectors is?

Basically when I fit the PC3 to my bike (k8) I get fuel injector 1 low voltage error code. Goes away when removed. :whatever:

Any pointers would be appreciated. :popcorn:

Without the pc3 you don't have this error, so I think the pc3 is the reason.

They can go faulty

Try doing a firmware update on it and then try again - if it still throws up an error then the PC3 is faulty

(note the bar across the middle of the screen for Software)

Just to check though - you do have the wire connected to the correct terminal (negative)?

I had a fault with PC3 with worn sockets in the plugs, I removed the plug O rings and the pins were able to pull up better and the fault went away for me.

My first thought too. They helpfully* coloured the earth terminal on the fly led red so you couldn't confuse it with a power lead.
