It sure does. You can feel it with the light patter from the brake pedal before the ABS goes off.

I thought that was just the ABS , was thinking because there is no steering angle or yaw sensors it couldn't have EBD, but must have been thinking of ESC.... been a big day[bighmmm]

I didnt say that the vehicle has any idea about tyre dimensions but the ECU has a map in it and "expects" a matching VSS for a certain driver demand, rpm and torque and the mapped values were calculated with std dimension tyres, once the tyres are much bigger those values are not matching anymore cos more torque and different TPS input is needed to accelerate to the same speed if you see what i mean, thats why the EGT is getting higher with bigger tyres, all these things are interdependent, believe me or not

When off-road with triple diff locks, you don’t need ABS, ETC, EBD, or HDC. So why not just interrupt the ignition-on signal (i.e. pull fuse 28)?

Or bridge one wheel sensor to the other side at the control unit when the corresponding diff lock is engaged. (using a relay, or some other form of magic)

Are there relays small enough to fit in the fuse socket? Turn on the lockers and kill the power.

Just be aware that pulling that fuse will disable the SLS too if it's fitted so bye-bye extended mode

Actually the air springs will stay wherever they were, so if in extended mode... That's what you've got!
