torque on demand problems

[idrivem5]

Well... I ran the error code check as described, short #8 to #4, and got 12 on the check light? Doesn't that mean there is nothing wrong?

I disconnected the blue/white wire connector above the diff... not wet. Blew it with canned air and reconnected.

Checked the tire pressure all are within 1lb.

But when I drive, the truck feels like it is missing some power and the TOD lights start blinking after a few miles?

Any ideas?

check all of your fluids too.. water in one of the differentials or in the transfer case could give you some odd issues too

I just looked under the passenger seat, it looks like I'll have to unmount the seat to get at the ECU?

And yes, unfortunately the cab had water over the seats.

I am thinking the only way to check the oils, transfer and diffs, is by changing them?

yes, you will have to remove the passenger seat. its very easy, there are (4) 14mm bolts. the two behind the seat are covered with plastic covers, just use a flat head screwdriver to pry the two sides off, then slide it back towards the rear door.

pretty much the only way is to change them. the diffs and transfer case all have fill plugs, if they are properly filled, you should be able to get to the fluid from the fill plug without draining, but you wont really be able to get a good sample from that
