GL500 - Rear SAM circuit diagram
Hi,
Our 2009 GL500 seems to think that a trailer is plugged in permanently. I have checked the trailer plug and wiring up to the SAM and everything seems ok. So I think the problem is on the SAM unit.
Does anybody have the circuit diagram for the rear SAM unit or at least the pinout for all the plugs.
