Just had the old bastard , fixed and now running well !! changed some bulbs in the dash and h vac etc so all lit up like a christmas tree. Does the audio controls on the steering wheel have lights behind them ? If so how do i get to them etc ? would be good to get them all working as should . Next bit is a bit harsher !!! 1 rear door seems to be super locked , how do i get open ? central locking only does front doors and i can live with that for the moment , no fob control at all , just key in drivers door . Cheers for any help .
 
dont believe the steering controls light up, mine don't and the symbols dont look like they are back lit, can't see anything on rave.

as to the rear door:confused:, some how try and get the door card off and disconnect the central locking and see if the lock can be undone, failing that, don't know if it was connected to one of the diagnostic machines the system can be reset or individual doors unlocked, someone may have an answer to that.
 
Dont light up !! well they bloody well ought to. I have read something about the door lock ,something about lowering window ,prise to one side and beat lock with a large hammer and long chisel/screwdriver ,i guess broken window is easier to find and replace than a new door card ?!! Just had diagnostic put on car as 3 lights on dash for brakes etc but diagnostic machine could not read abs system ? I only fitted second hand pump and accumulator 8 weeks ago and worked ok for that period .Now same problemas before 3 lights and crap brakes .
 
Can you get it over to Rick..he should have ABS software and can identify fault. Generic scan tools will not do it.
Regarding rear door locks:
These are fed from Fuse 14 (20amp)..check this fuse first. Try removing Grey plug C325 located at the end (Nearest the Drivers door) of the front (Nearest the pedals) of the Becm. Three wires control the lock motors for the R.H. door..Pink, Orange and Pink & Orange.

Also remove White plug C361, it's the one nearest the pedals on the opposite side of the Becm to the fusebank. Again three wires control the lock motors for the L.H. door..they are the same colours as the R.H.

Pink wire controls the Central Locking Motor, Pink & Orange wire controls the Superlock Motor. Orange provides return path for both motors.

Using "Jumper" wires, connected to Ground (Negative) and the other, fused to 5amp (Positive), put the Negative jumper to the Orange wire pin on the disconnected C 325 or C 361 and briefly put the positive (Fused) wire to firstly, the Orange & Pink wire..the motor should unlock..if it doesn't, try it on the Pink wire. If the motor unlocks the door, repeat the procedure on the other plug.

Refit the two plugs to the Becm and try the Central locking again with the fob.

You may have to remove the seat skirt to access the two Becm plugs or at worst, the seat to give access, but you know how to do that !!!!
Let us know how you get on.
 
i know its a pain in the rear john but can you give the same sequence for rear pass door, in simple terms for me or is the above for both doors. one of mine don't work on c/l and i can't get the mech out to strip it down, just wondered if i can put m/meter over it and see if the wires dead of the motor??
 
Hi Gav......The rear door locking setup is fed separately from the Becm via fuse 14 and that is the first port of call, followed by plugs C361 (LH) and C325 (RH). Have a look at page 296 on the Electrical section on RAVE and you will see the relevant circuit(s). You can either check the pinouts at the Becm for voltage with the plugs removed or check at the plugs themselves if you insert a probe into the relevant wire where it enters the plug whilst it is in the Becm. If you are getting voltage at the plug, then obviously the fault lies between the Becm plug and the motor itself. I would think it highly unlikely however that both doors would fail at the same time and looking at the circuit there are no switches on the rear doors to confirm whether the doors are in a locked or unlocked state, only the "Door ajar" switch which doubles up to operate the interior lights.
I am thinking along the lines that somehow the door locking has got confused and maybe needs resetting by physically opening the locks.
It's a strange one because the Becm which I supplied to him following his own "frying" was tested on my own P38 prior to reprogramming and everything worked 100%.
 
The outputs to the central locking on each of the doors can be checked with the Becm software, that is, they can be operated remotely to ensure whether the Becm is operating them correctly and verify that the motors , wiring and signal is o.k.
 
Morning John , i will have a bash at the wiring /plug becm thingy today , went for its mot yesteday and luckily the back door does not need to open is only an advisory !! Car is running fine is just the locks problem and the abs which was a problem before the becm scenario RR dealers machine isstillout of order for diagnostic , a guy in an independant tried to read it and came up with non contact to ecu abs system etc . So apart from 2 x wiper blades and 2x trailing arm bushes willpass mot with flying colours isjust idont want tochuckanother £300 at an abs pump if is something else ,onlyjust fitted a second hand one 8 weeks ago and worked fine for short period . Iwillget hodof Rick see if ican get a visit to him .
 
whiteplug in doeswork both front doors centrallocking off the door button ?????!!! white plug out stops front door central locking working ? !! soihave found so far
 
White plug is LH rear, Grey is RH rear.
Looking quickly at the circuit, those two plugs only do the rear doors.
If you get hold of Rick and arrange something about your ABS, get him to use Becm module SM022 and operate the "Faulty" door locks using the diagnostics. This will confirm whether the wiring and components are working or faulty.
 
There must be something in between the white plug and door lock ? if iput a tester in grey plug and push door locks it reads 13 briefly as door locks atuate front doors , so if i put power to rear doors /white plug i should get power to locks ?
 
white pug out /no doors work . white plug in front doors work together off the door button . grey plug out front doors work together /grey plug in front doors work together . nothing working rear doors
 
The fact that you are getting a pulse on the grey plug when you operate the front doors indicates that the rear door motor R.H. should operate. What colour wire are you getting the 12V pulse on at the grey plug ?
 
multi meter :red prong in orange ... black prong : in orange/pink and pink press front drivers door button all read 13 on meter briefly on open and closing of lock . This is right for both becm plugs white and the grey one . This says to me there must be a problem between becm and rear locks ? as power is being sent by becm to those wires at locking and unlocking time .Adding power via a lenghth to battery + and - is not making any difference as power already exists at the said wires on the movement of the drivers door lock ....
 
is there something between the becm and the locks ? i guess the next thing is to remove the rear door card of the door i can open and see if any voltage is reaching that lock ? as that only open and locks if i manualy push and pull button up and down
 
If you are getting a pulse of power to the wires that power the locks when the "Switch" is operated then that suggests that somewhere after the Becm there is a break and the power is not getting to the motors. You now need to move on to the connections and the motors inside the doors and check that you are getting power there.
