EWS-DME synchronization code in DME MS43.0 DTCs description in DME MS43.0, EWS3, SRS MRS4 Copying ZCS (IKE - EWS) and FA (IKE - LCM) coding Read chassis, model, engine, gearbox etc. It can scan and clear error, read and write EEPROM, reset inspection or service interval. If he brought the alarm module from a US seller that could be the reason.BMW Scanner 1.4 a PC interface connecting to USB port and works for chasis E38, E39, E46, E53, E83 and E85. Very Interesting, didn't know they used different frequency between the US and Europe.
With the info in the above paragraph.another question arises.and that is.does the RF of the key match the RF of the receiver? BMW makes keys and receivers that are either 315 MHz or 433 MHz: And in this case, the key's RF signal must match the frequency of the receiver. But if using the buttons on the keyfob.the arming/disarming signal is transmitted over an RF (radio frequency) that is either 315 MHz (in North America) or 433 MHz (in Europe and many other markets in Asia & Africa). Question: are you only "arming/disarming" DWA (anti-theft alarm siren system) using the remote buttons on the key? Or have you tried arming/disarming using the key manually in the driver's door lock cylinder?Įither way should arm/disarm the system. Straight after installing I could arm and disarm without the siren going, however after being connected overnight and charging the internal battery, I had the same problem.ĭitto in checking if the GM has been coded to check for the presence of FBZV/DWA (remote central locking and anti-theft alarm siren). My best googling suggested that the siren was faulty, so I replaced it with another one. My best guess is that the siren is thinking it has been disconnected from the car the moment it is unlocked, but I can't figure out why it arms itself, but won't disarm. I can re-arm the car and the siren keeps going. I can start the car and drive away, siren keeps going.
I can unplug the siren, and it keeps going. Siren goes 30 seconds on, 10 seconds off, for about 5 minutes. Problem is - the instant I unlock the car, the siren sounds. I have coded with P.A Soft BMW Scanner 1.4, and the LED on the mirror behaves correctly. Mirror with LED fitted, siren fitted, tilt sensor fitted, hood switch fitted, unfortunately connector for ultrasonic sensor is beyond reach from the hole in the roof, so I may need to drop the headliner - but the alarm should work without it. I used the official retrofit instructions and parts from ebay. Since I park on the street and have had a window broken before, I thought an alarm would be a good addition (not standard for euro-spec). I have successfully retrofitted navigation and Bluetooth, and both went smoothly.
