TK v300 DSR Error

[Andri]

Hi all

I've got a truck with a V300 showing on the display ( -C- ) without brackets.
Unable to switch on or off. As if it has crashed.
Anyone knows what this means and how to get rid of it???
Have checked the plugs and connections as i thought it might be a communication error.
Please any advise would be helpful.
Thanks
Andri

Hi Clive

Thank you for the reply.

I've sorted it out for now, checked all wiring and connections again and then went inside the micro (opened it).
Found on one chip in had corrosion on the sides of its pins. Brushed it off and surprised me. It worked! Keeping fingers crossed its sorted.

much appreciated

Andri :)
