Attessa Code 22 - Ets Oil Level Switch Or Circuit

[JimmyRickard]

Hi guys, I fired up the car today and noticed I had a solid 4WD light on. I checked the attessa which flashed 22 times, which according to the manual is "ETS oil level switch or circuit"

The Attessa fluid is above max, and the circuit appears to be fine as we checked it with a multimeter.

I have three questions:

- If the fluid is fine, are there any other issues I need to be aware of?

- I can check the fluid levels myself, is there a way to bypass this sensor?

- If the Attessa system has an error, does it turn off 4WD? This is probably my biggest concern as I can't test it until I get out to the track.

Cheers guys.

Have you changed the clutch recently at all? Always possible air has gotten into the system.

Nope

Checked brake fluid level?

[JimmyRickard]

I haven't I will check it out. Is brake fluid level monitored by the Attessa? Why would it show up as a fault for 4WD?

I just know from experience that it does. Same sensors for Atessa as for ABS.

If there is a fault with the ABS will it affect the use of the 4WD system?

Yeah ABS and AWD are tied together. There's a flappy rear wheel speed sensor on my car and my ATTESA and ABS crap out randomly.
