For the uninitiated, Cactus is Oz slang for "unserviceable", there are also a miriad of other terms which adequately describe the same condition, as we all know, but the moderator doesn't like the use of some expletives. Now, to the issue, a mate has an '03 and the ABS apparently is not operating. He has had it to a dealer and they charged him $329 to put the GS911 on and tell him the ABS has a fault and the modulator unit must be replaced. He asked for some more detail after he got back up off the floor because they had just told him the unit is $4100AU, plus $1000AU to fit it !! The dealer technician would not elaborate on the explanation of the fault, so I'm wondering if they actually know all they need to know about this problem. Any advice, or additional checks I could assist him with ?? Is there a relay for the ABS unit on the '03 ? Thanks, Dennis.
