Hi

wonder if anyone could guide me on this one
car came in with no indicator & main beam tell telltale,no radio/satnav display, park sensors & reverse lamps
six fuse boards on this car, fuses all good
global scan would only connect to transmission,no codes
ran a can test & first result was short to ground,rechecked & both lines ok! using dec, not scoped yet
after looking for main ign relay autodata not that clear but found some in o/s/r boot area, there are four relays 2 light green 5 pin one is voltage protection relay 1 & the other voltage protection 2, soon discovered if this relay is pulled all systems come back on line except the radio & cd,the nav works & its a combind unit
the ad wiring diagram for this vehicle is poor to say the least

My understanding of the use of this relay is limited other than its there to protect vital hardware
the relay functions fine off the car,its a standard 5 pin
ive disconnected the audio unit hoping to see a change in the electrical systems to no avail fuse 43 in glove box serves the relay along with lots of other systems
alternator charge rate is good along with batt condition
sorry for the long post feel the 2 hours wasted on this car are down to my poor data if someone has a schematic for the rear fuse board/relay plate on this one it would help
could someone explain the relays full function it would help greatly
one of you guys may of experienced the same issue and could assist on this one

Keith
ps: a global scan with the relay disconnected only revealed a coulpe of power supply codes/not present
