Hello everyone,
I have a problem in my cx-9 2009,
It started yesterday when suddenly the TCS light came on the dashboard, and after 5 minutes the AT light came on after, as the transmission stucked on 3.
I switched of the car for 5 mins, and switched on again, all lights went off.
but after 5 to 10 mins all came again with same sort.
Also there abs, break and 4 wheel lights shown but they are not remaining on the dashboard.
I made a computer check, please see the pictures and the report hereby, as I appreciate anyone can help.

 

U codes are communication codes.

1st step : Get your battery & charging system professionally tested.

 

thanks you for your reply,
even if it's no battery light showing in the dashboard, it could the problem?

 

Check out this video. I am not sure if 2012 has can system. Our 2020 cx-9 had a break in can communication wires that presented several codes/symptoms similar to to yours. I was able to use this video to determine there was a break somewhere. Hope this helps.

 

A bad or dying battery can cause all sorts of issues.

 

battery checked = 13
Charging alternator = 14

The technician said is ok
Is there any next step ?
Thank u
