C-Max 1600 Petrol 2005. Can-Bus code

[Paul Kelly]

Hola !

Been out to look at a 2005 C-max 1.6 petrol today. Report of Engine Mil Light on. When I got there, she says that the light has now gone out.

I did a network test on the car using IDS and there was only 1 fault stored, this was in the IC ( instrument cluster ), fault code U1900, Can-bus communication error. There are no other codes or running problems reported with the car.

I cleared the fault code and then did an IC and PCM software update.

I'm sure this is nothing to worry about and have advised customer to inform me if it returns.

Can anyone advise on anything I should be concerned about for future return visits?

I thankyoo 

Paul

hi paul

can't really give an explaination but i see this u1900 code stored regularly, nothing to worry about unless there is an instrument cluster problem

I find this pops up with a low battery at times  Focus and Cmax do not like low batteries

Thanks guys. Just what I wanted to hear. 

I did ask about the battery charge, nothing out of the ordinary reported here , nor anything out of the ordinary with the IC.  Maybe something to keep an eye out for.

They want me to go back in a week or so to service their Vectra so I will have chance to quiz the lady again.

Thanks again

Paul
