Hello
I bought range rover L322 2003 with 3.0 TD6 for my girlfriend and low range has never been worked, i thought it is just transfer box motor but i removed it, tested and cleaned (Just like powerfuluk video) Everything seems to work in bench but when i select neutral and pull low range button it doesnt do anything. Earlier this year it did show "select neutral" text on instrument panel when car was started but now anymore.

On iidtool i read fault codes it gives
0x5230 Motor A and B off, A short circuit to ground
0x5234 Motor A and B off, B short circuit to ground
0x5238 Motor A and B open load

And TCM gives "0x99 CAN bus transfer box range error: general fault"

Instrument pack gives code 0x8D transmission interface bus fault

Is transfer box ecu toasted?

ECM gives p0380-80 Glow plug relay failure - glow relay defective and P1180-01 Low side fuel pressure sensor plausibility (fuel filter) - reduction in quanity due low pre pressure. I guess i need to change glow plugs and fuel filter also.

 

Hello, did you find the Problem? I'm having the exact same problems with my 03 Td6.

Greetings
