Hi, my Vogue SE has an ABS/TC fault, the blink code comes back with code 2-3 which apparently does not exist! However working with the assumption that its the same as the early P38 ABS system this would point to the pressure switch, so I acquired a P38 ABS pump and took the pressure switch from that and fitted it but there seems to be no difference, is there any realistic way to test the switch? the pump runs and shuts down when pressure is reached with both pressure switches

Never heard of code2-3 or anything like it.
Anyone know what diagnostics he should be using?
Early P38 uses Wabco C not sure what they put in LSEs

So the 2-3 is the abs blinking when you short the OBD pins ?
Yes, it is WABCO C in a very very late RRC with ABS and Traction control, in fact it's more like a p38a that looks like an RRC in many ways! but I have just noticed two of the three wires on the low brake fluid level switch have come adrift and that the ABS pressure sensor switch ion the P38a is wired to that before the ABS ECU, and the 2-3 points to the pressure switch.

On a P38 there is an orange wire on the compressor plug, you should have continuity between the orange and the black wires.
If no continuity but the compressor runs with Earth put to orange wire, thermal switch is duff.

I have made progress on this, code 2-3 was indeed being caused by the broken wires on the brake fluid reservoir cap and that has now been cleared. However it then showed code 2-6 and I have now fitted a new brake light switch (I tested the old one and two sets of contacts showed permanently closed regardless of position) I cleared this and now I have code 2-12, which I believe is a sensor needs reseating on the front axle, I tried clearing this but it’s has remained (although it’s not been driven) I am wondering how it knows the air gap is too great without being driven, and a little suspect at the codes going 2-3, 2-6 and then. 2-12!
