Hi my 4wd light keeps flashing on my dash. When I pull over for a short time is stops. When I continue to drive after about 15 min it starts flashing. All four tyres are 235/60 r18. Two on the front are brand new and the two on the back are half worn. Could you please help me with this problem.
Thank you

Hello,

It sounds like you have a shaft RPM sensor that is out but to be sure lets run the codes to see what comes up. But it sounds like the 4WD controller is out. They hang down in the water which cause corrosion so check the connector before installing the new one.

Please let us know what happens.
