Tip & How-To about BMW 750

How to on BMW very easy recognize where it is a demaged sensor, if Your PDC system is faulty?

First step activate the PDC system in operation mode!
It says that there is an obstacle, and she is not!
Easily recognize when your finger simply attach on the center sensor, he is well visable and there is a 4x pieces in the rear bumper and in front bumper when is.
Touch your finger on the sensor when easily pulsed, can feel You this or you can hear the faint pulsation. When not pulsed is defective and pernamently says is a obstacle here!!! And your PDC system is in failure!!! This sensor must be a changes!!!!

Save Your money and way in the repair where you pay money to not that the car is repaired, but only that tells you what is wrong and will need to replace

You go try it in your BMW with the PDC, it works!

There isn't a fuse just for the check engine light fuse . There are fuse's that power the whole insturment cluster . Check engine light not working ?
  • The malfunction indicator lamp (MIL) is never/always on
  • Circuitry.
  • Powertrain control module (PCM).
  • Instrument cluster.
  • Go To Pinpoint Test O .

PINPOINT TEST O: THE MALFUNCTION INDICATOR LAMP (MIL) IS NEVER/ALWAYS ON Test Step Result / Action to Take O1 RETRIEVE AND RECORD THE DTCS FROM BOTH CONTINUOUS AND ON-DEMAND PCM SELF-TESTS
  • Key in OFF position.
  • Connect the diagnostic tool.
  • Key in ON position.
  • Enter the following diagnostic mode on the diagnostic tool: PCM Self-Test.
  • Check for PCM DTCs from the continuous and on-demand self-tests.
  • Are any PCM DTCs recorded?
Yes
REFER to the Powertrain Control/Emissions Diagnosis (PC/ED) manual.

No
GO to O2 . O2 CARRY OUT THE INSTRUMENT CLUSTER INDICATOR LAMP CONTROL ACTIVE COMMAND USING THE DIAGNOSTIC TOOL
  • Key in OFF position.
  • Connect the diagnostic tool.
  • Key in ON position.
  • Enter the following diagnostic mode on the diagnostic tool: Instrument Cluster Active Command.
  • Select the instrument cluster warning lamps and chime active command. Trigger the indicator lamps active command on then off, while observing the MIL.
  • Does the MIL illuminate when commanded on and turn off when commanded off?
Yes
GO to O3 .

No
GO to O4 . O3 CHECK FOR CORRECT PCM OPERATION
  • Disconnect all the PCM connectors.
  • Check for:
    • corrosion
    • pushed-out pins
  • Connect all the PCM connectors and make sure they seat correctly.
  • Operate the system and determine if the concern is still present.
  • Is the concern still present?
Yes
INSTALL a new PCM. REFER to Section 303-14 . TEST the system for normal operation.

No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. TEST the system for normal operation.

HOW DO I PROGRAM A NEW REMOTE


You take it to the dealer !
Important: All transmitters which are to be recognized by the remote control door lock receiver (RCDLR) must be programmed in a single programming sequence. If the system is placed in program mode it will erase all previously programmed transmitters upon the receipt of the programming signal from the first transmitter. Up to 4 transmitters can be programmed. Do not operate or program the transmitters in the vicinity of other vehicles that are in the keyless entry program mode. This prevents the programming of the transmitters to the incorrect vehicle.
  1. Install a scan tool.
  2. Use the scan tool in order to access programming: Vehicle Control System/Computer Integrating System/Module Setup/BCM/Program Key Fobs.
  3. Press the START soft key on the scan tool.
  4. Important: The scan tool must stay connected until all of the transmitters are programmed.
  5. Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of 5-10 seconds, the scan tool will indicate that the transmitter is programmed.
  6. Repeat the previous step in order to program up to 4 transmitters.
  7. Remove the scan tool.
  8. Operate the transmitter functions in order to verify correct system operation.

the headlights of my 1998 caravan stay on all the time, not only disabled if you disconnect the battery, wath I can do?


Your headlamps are controlled by relays that can be fired by either the body control module (BCM) or the multifunction switch... the turn signal assembly. It might help to find out which of the circuits are currently stuck on, either high or low beam.

Note that each relay is hard-wired to the BCM and also wired to the multifunction switch (dimmer switch) for switching between beams and optical horn operation. Grounding of either of these circuits will energize the relay, keeping the headlamps lit.

Your relay box under the hood (PDC) is where the headlamp relays are located. Pop the cover off and pull each one of these relays out with the headlamps turned off and the battery connected. When you find the one that's energized, the lights will go out. Feel for the <click> as the relay is pulled and placed back into the PDC socket. If no click is felt, yet the headlamps turn on and off with relay removal/ replacement, you will simply have a stuck relay. Clicking means the relay has grounding on the control circuit, which takes us back inside the van.

I'd start with the multifunction switch. Give it several clicks in dimmer mode to see if it extinguishes the headlamps. If it does... obviously, this will be your problem.

If not, it would be a good time to disconnect the switch to view what the reaction will be. The column shroud covering the MFS uses a #2 Phillips to remove the three screws on the underside of the assembly... then it's pulled apart at the seams. It will fight you a little bit but that's normal.

If disconnecting the MFS extinguishes the headlamps, that's your solution. If not, we'll have to investigate headlamp switch operation and/ or BCM harness wiring. The last stop would be BCM replacement, as it defaults to headlamps on when it no longer sees an active headlamp signal (bad switch or open circuit) and grounds the relays.

Let's hope it's at the multifunction switch!

Good luck

pdc fault


When is only one piece of a broken sensor for PDC, so the whole system fails. Where is faulty can be reliably checked diagnosis

I have a little trick! When you provide your PDC up and attach finger to the sensor - must easily pulsing! When if not, that's bad!

Check out and You see.

i need help on how to change a back brake light in a 2000 chevy cavalier


You should be able to open the truck and pull back the carpeting just around the area of the brake/reverse/signal light housing. There are normally a few nuts, almost always 3, and they are quite easily removed by either using a small adjustable wrench or a small pair of pliers. Just be careful when removing them and do not apply much pressure as they are constructed of very thin metal and will deform easily. After you remove the nuts, the housing should pull free quite easily and allow you access to the bulbs. Simply turn them 1/4 turn counter-clockwise, you'll be able to feel it unlock, and pull the bulb from the housing. Replace the bulb, wipe your finger prints from the bulb with a soft cloth and reverse the steps listed above. The oil residue from your fingers will often cause the bulbs life to be shortened a great deal.
