Thoughts on TOD disconnect

[vovkus]

There are 3 possible modes for VX:

1. Regular TOD mode.
2. TOD Off, Clutch Solenoid ON (50/50 HI)
3. TOD Off, Clutch Solenoid OFF (2WD HI).

To prevent Check TOD error, the TOD control unit must be connected to the dummy load.
Provided diagram shows how to do this.

You need two switches. One for TOD ON-OFF, and second to
switch between 50/50 HI or 2WD HI.


Relay 1 used for locking Clutch ON-OFF Switch in TOD ON mode.
Relay 2 used to connect Clutch Solenoid (In TOD ON mode) or Dummy load (in TOD OFF mode) to the TOD Control Unit.

Heh. So I couldn't resist trying this anyway. Fun to build, but no, it doesn't work as Tone said it wouldn't.

It does work as a TOD disconnect without the Check TOD light, but feeding 12V directly to the clutch solenoid (both switches on) did not get me 50/50.

Oh well.
