FWD Fuse questions

[moo]

Ok the first one, how does this fuse work?

 

Second, where is the rest of the wiring located.

 

Lastly, does anyone think it is possible to interupt that curcuit with a switch? (With the requisite wiring, of course).

How does the fuse work? Please PLEASE!!! search before you ask questions - this has been covered many times. In a nutshell, it forces the Duty C solenoid to not engage the clutches in the back of the tranny.

 

Where is the rest of the wiring? Well, the fuse just sends a signal to the TCU saying to engage FWD.

 

Interrupt with a switch? Why bother. The FWD fuse isn't supposed to be in except in situations where only ABSOLUTELY necessary. It doesn't gain any gas mileage or make less wear and tear on the tranny. If anything, it's WORSE to drive an AWD car in FWD mode just because you feel like it. You use the FWD fuse for testing, not for normal driving. If you want a FWD car, get a FWD transmission.

Thank you, and sorry for the lack of search.

Fuse energizes the AWD solenoid to disable the AWD

 

Fuse bypasses the TCU in such a way that the TCU does not throw a code, but does turn on the fwd light.

 

NO its not that easy, as has been discussed here, you will throw a code almost every time. Also the reverse you will damage the AWD unit if its not done properly, its not just the matter of throwing in a switch.

 

 

Also if you want a 2wd car why buy a subaru? Disabling the AWD does nothing for gas mileage, and changes the handling to some degree, but defanitly changes the traction, as the awd is always adjusting the torque split.

If a switch is used because of torque bind, it wont work for long.
