I've also got some issues with the TOD system.

In dry conditions while driving the TOD will throw a lot of power at the front wheels even when driving fairly passively. This seems to happen the most between 30-50mph. It makes the ride very jerky and there is an audible whump-whump-whump (turn up your speakers to hear it) when it occurs.

The TOD check light does not come on, but the light does appear to be working (lights up during the self-diagnostic check at startup)

What should we be looking at first? Sensors? Connections? Tire pressure on all 4 wheels is equal and the 4 tires are the stock size and of the same make and brand.

Any help with this is hugely appreciated.

Thanks!
Eric
