Thanks Trevor, that confirms the info i found.
One of the things which does chafe with control systems is the illogical algorithms and protocols which seem to preside pretty much across the manufacturers-
The sounder which goes PING if you activate the handbrake whilst still crawling is the same sounder that goes TICK when i am indicating...and the PING overrides the TICK, such that one is unaware whether one is still indicating right for several seconds- unsafe given the propensity for self cancellation with indicators. I have de-activated the handbrake PING ages ago by disconnecting the switch.
If you or i were designing the ABS/ESP algorithms a fault in the rear ABS would shut it down on the rear (complete with ALL the ESP differential braking functions) but would leave the ABS on the front axle still in operation. This, i think, would add extra parts and cost to the moving systems of the ABS module- which might explain why they don't do it!
