AWD system malfunctioning

The modules might not be talking because of a burnt fuse or the module itself is out. Does it list the modules but not go into them? What kind of scanner do you have? Yes the AWD and ABS should show up in the scan.

This message does NOT always mean actual overheating, it often means:

“I can’t communicate with the module that controls AWD, so I’m disabling it.”

So I would turn all systems on and then check the fuses in both fuse panels. This guide can show you how.

If the fuses are good, chances are the ABS control module is out which is common on Toyotas. When you turn the key on (engine off) does the ABS waring light come on? Please go over this guide and get back to us.

Thank you I will do so and let you know Ken. I was expecting the abs to stay on days indicating fault, but it does not, only when the ignition is open then the light appears, but when the car is idling you won’t see the light as well no communication.

Hi Andrin,

Yep, the module can be failing intermittently. Also, it can be a bad connection at the ABS module. With the scanner can you get any codes at all?

Not at all. No communication

I would check the fuses and the ground to the ABS module and if they are good replace the the module. Here are the fuses you need to check and the grounds for the system as well. Check out the images (below). Let us know how it goes
