Question about 1997 BMW 5 Series

1 Answer

I have recently added a Bluetooth ULF module to my car, every thing works except sound. I purchased the system from bimmernav.com, they supplied the old to new harness to connect from the original harness to the new, a new BMW Professional BM54 radio and BMW Bluetooth ULF module. The car is a 1997 BMW 540i Vin no WBADE 62030 BW71103 Originally it was equiped with: TV,Radio and tape deck. has since been fitted with: GPS navigation system and CD player. At this stage when all the above are connected to the new harness, new radio and ULF Module, all are working correctly (except for sound)even the telephone which was the main purpose of this excersise picks up the phone and all its features. thank you, Richard Jones.

Hello Richard, when the ulf module was installed, was the jumper plug installed in the blue 26 pin connector in the left rear corner near the GPS unit. I think that if this plug is missing, you will not get any sound for the interface. This plug is required for vehicles with nav. I think it is called the Voice Input jumper plug.

Fuel Pump Flow Control Module (FPCM) - LMF
The fuel pump flow control module (FPCM) is a serviceable GMLAN module. The FPCM receives the desired fuel pressure message from the engine control module (ECM) and controls the fuel pump located within the fuel tank to achieve the desired fuel pressure. The FPCM sends a 25 KHZ PWM signal to the fuel pump, and pump speed is changed by varying the duty cycle of this signal. Maximum current supplied to the fuel pump is 15 amps. A liquid fuel pressure sensor provides fuel pressure feedback to the FPCM.
Electronic Returnless Fuel System (ERFS) - LMF
The electronic returnless fuel system is a microprocessor controlled fuel delivery system which transports fuel from the tank to the fuel rails. It functions as an electronic replacement for a traditional, mechanical fuel pressure regulator. A pressure vent valve within the fuel tank provides an added measure of fuel pump flow control module (FPCM). Desired fuel pressure is commanded by the engine control module (ECM), and transmitted to the FPCM via a GMLAN serial data message. A liquid fuel pressure sensor provides the feedback the FPCM requires for Closed Loop fuel pressure control.
If your vehicle has this system check it for DTC'S - diagnostic trouble codes . Will take guess work out of it .

DTC P023F: Fuel Pump Control Circuit
The engine control module (ECM) supplies voltage to the fuel pump flow control module (FPCM) when the ECM detects that the ignition is on. The voltage from the ECM to the FPCM remains active for 2 seconds, unless the engine is in crank or run. While this voltage is being received, the FPCM supplies a varying voltage to the fuel tank pump module in order to maintain the desired fuel rail pressure.

Do your speakers work? When the bluetooth connects, is there a sound that indicates that you are connected? I cannot answer this question without knowing more of the problem.

Your problem is the fuel pump control module , do you know what this is !

I had the same problem. Everything worked except the sound. There is a small button next to the CD player that is a reset button. Press that and the audio came back. You have to reset your presets but at least the sounds works.

That means that your car wasn't fitted with bluetooth module from factory. You can purchase at dealer but you're talking around $1k and from what I hear isn't the greatest.
