Whats the state of yer Battery ??? ... (No it aint a daft question!!) The VERY FIRST thing that pops up on a P38 with a "Failing" Battery is a whole raft of ODD gearbox messages ...
Before you start rippin things apart just get yer Battery tested (Both Static & Load) ..

You would need to look at RAVE for that, but I would have thought the XY selector indicates neutral which is needed for the transfer box to operate. I'm sure someone who knows will correct that if I'm wrong.
cheers m8 i`ll have a look at the xy selector tomorrow as iv`e heard they can get water in them
The glowing red led is normal and its the same on every P38A auto. It's a small back feed from the becm and is a very useful diagnostic tool as it only glows like this while the becm is in its awake mode. If u ever have a flat battery issue, u can check this lamp to see if the becm is going to sleep. Ref x,y&z switches, check these by whatching the PRND display on the Ipack, this info comes from the XYZ switches via becm. If the becm sees an illegal combination of the 3 signals, it will then inhibit PRND info being displayed on the Ipack. The becm sends a gnd signal to pin 34 on the t box ecu connector when vehicle is in neutral. Check this signal if you can. If you have an old ecu fitted, then some one has been playing around with the electrics in this area, so suspect damaged terminals especially on the ecu connector. Only way to check properly for openned up terminals is to probe with a corresponding male terminal.
ok guys thanx for help still no joy got it to go into high and low fine today got it in high with no problems no messages on dash no select neutral all good till i turned off the igntion for 5 minutes and went back to it put key in ignition on back to select neutral the build date on my transfer ecu is 96 my car is a 2001 i`m sure i have the wrong ecu i really need to find a transfer ecu for a 2001 does any one no ov anywhere i can get the part number from for a 2001 tranfer ecu as the stealers won`t help with advice cheers guys hope someone can help i`d be very gratefull
