Hello all im still trying to track down my issue regarding ESP/ASR , im looking at the wiring numbers on the ESP81 so there is 4 wires

M7804, 9000V,9001V, 7112B,


The first one looks like an earth how do i decode the other 3 and are Peugeut wiring colors the same

And is there any way i can check the Gyrometer ESP81 with a multimeter off the car?

Thanks

M7804 is an earth
9000V is the High Intersystem / Can bus
90001 is the Low Intersystem / Can bus
7112B is the Angle sensor + 12 V power supply

ok so ive checked the gyrometer ESP81 for power and it does have over 13v at the connector so its getting power!! the worst code im getting is the C139B sensor signal fault , and its a permanent fault now as ive tried 2 second hand gyrometers im either very unlucky and thay have all failed or this is a wiring issue, now my car has been into Citroen and they said firstly its your brake switch I told them no ive just put a new one in with the new harness.. they then said its a wiring issue but wanted to charge me £86 an hour to trouble shoot it so I told them that kind of money is not acceptable and we parted company I told them I was very disappointed and I thought they would know the Citroen fault codes and systems better than any one but they actually know no more than little me!! so im at the end of what I can do ive troubled shooted this and tried my best to sort it … its going to a local garage who is known to be very good at tracking electronic issues next wed , all the codes point to the Gyrometer , I may in the end just have to buy a new Gyrometer but also might not be that and I will have wasted a lot of money, as it stands no one knows how to check a gyrometer unit out of the car?
