Hi. Thanks for using JA! i will try and help you out.
The coolant diverter valve is located in front of the turbos. It is inserted into the precooler. It has 2 wires connected to it.
Please let me know if you have any more questions.
yes i have code284-6
Thanks for the information. This codes means there is an open circuit in the wiring or the diverter valve itself. This is pretty common due to the location of the valve. (Near the hot turbos).
Here is an image of the location.
