ELECTRONIC ~MMOBILIZATION (EWS) E39 cars are equipped with a passive theft-prevention sys- tem. The Electronic Immobilization System (EWS) makes it impossible to startthe engine using any means other than the special lkeys furnished with the vehicle. NOTE- Replacement EWS control modules or DME control modules must be electronically aligned to each before the vehicle will start. This requires the use of the BMW Service Tester (DIS- plus, GT1, or MoDiC). Without alignment, the engine will not crank (for example: swapping a known good DME control module into another vehicle for test purposes will result in a no crank situation). In the EWS system, the ignition key is embedded with acom- puter chip (EEPROM) and coded. The key communicates with the vehicle using a transponder in the lkey and a ring an- tenna surrounding the steering lock cylinder. Up to 6 replace- ment keys are permissible. Only an authorized BMW dealer can provide replacement keys.
Central Locking and Anii-Theft - If the starter engages, the following EWS inputs are function- ing normally: Ignition key Code function Transmission range switch or clutch position switch Engine speed sensor NO JE - If a vehicle key is lost or stolen, the electronic authorization for that key can be cancelled using the BMW scan and di- agnostic tools DISplus, GTl or MoDiC. Force applied to a ley can damage the electronic circuitry in the key A damaged ley will not start the engine. In that case, a new key should be purchased and initialized by an authorized BMW dealer.

CA UTIOI\C Prior to disconnecting the battery, read the battery discon- nection cautions given in 001 General Warnings and Cau- tions. - EWS II: Control module is accessible from behind glove com- partment. Remove trim below glove compartment. Lower relay and module holder to access EWS control module EWS Ill: Control module (A836) is located to left of steering column, below dash. Remove trim below steering column. Unplug module and remove from holder. Installation is reverse of removal. Transmitter / receiver module Only EWS II vehicles are equipped with a separate transmit- ter! receiver module attached to the steering column trim on the right side of the column. Ring antenna - Remove ring antenna using BMW special tool 61 3 300. Remove upper and lower steering column trim. Disconnect harness connector to ring antenna. Pry off ring antenna using BMW special tool 61 3 300 or equivalent flattened prying tool.

51 5-24 l~entral Locking and Anti-Theft ANTI-THEFT SYSTEM (DWA) When the anti-then system (DWA) is armed, the doors, hood, windows, trunk lid or tailgate are monitored against forcible entry by switches and sensors. The vehicle is protected against being jacked up or towed away by a tilt sensor. The control electronics for DWA are integrated in the General Module (GM). In addition to the control electronics, the sys- tem includes the following components. * DWA horn DWA LED indicator - Tilt sensor - Monitoring switches and sensors The system can be armed or disarmed from the drivers door lock, trunklid lock, tailgate lockorthe remote transmitter (FZV Itey). When armed, the alarm horn soundsfor30seconds and the low beam headlights and turn signals flash for 5 minutes. The electronic immobilizer (EWS) is also activated when DWA is activated. The alarm is switched off immediately if key is inserted in door loclt or FZV key button is used. DWA LED Status The DWA status LED is located in the rear view mirror (ar- row). When DWA is armed, the LED flashes slowly to indi- cate armed status. The LED and exterior lights flash once and the alarm horn sounds when the system is successfully armed ordisarmed. The LED will continue to flash slowly denoting the armed sta- tus. If any monitored input is not closed when the system is armed, the LED will flash rapidly for 10 seconds to indicate the fault. Tilt sensor - 4 The tilt sensor, located on the left side of trunlt or cargo com- - partment, consists of a conductive liquid chamber, a proces- sor board and metal probes. The probes are submersed in the liquid and produce a resistance value dependent on the tilt of the sensor (angle of the vehicle). This resistance be- comes the reference value when the DWA system is armed. .-
51 5-25 Central Lockina and ~nti-~heftl 1 Tilt sensor operation: 1. DWA armed, vehicle level. Tilt sensor sends HlGH sig- nal to General Module (GM). 2. DWA armed, vehicle tilted. The fluid moves in sensor, changing resistance value. HlGH signal changes to LOW signal. GM activates alarm. If the vehicle is jacked up or lifted in any way, the angle of the liquid changes, producing a change in the resistance value. The sensor signals the GM to activate the DWA alarm. The sensor resets at the new angle. This allows the DWA system to remain armed and to reactivate the alarm if tlie vehicle is moved again Locking the vehicle twice within a few seconds will deactivate the tilt alarm sensor while arming tlie remainder of the sys- tem. This allows the vehicle to be transported in an armed state without activating tlie alarm. Interior protection The interior motion sensor is mounted in the center of the headliner panel. Due to the design of the vehicle interior, the sensor must be installed in the correct direction to ensure proper operation of the system. lnterior sensor FIS (1997 - 1999 models) 4 When the alarm system is armed, the FIS sensor emits elec- tromagnetic waves at a frequency of 2.45 GHz. As long as nothing is moving in the vehicle, the waves are reflected baclc to the sensor at the same frequency. If a foreign object enters the vehicle, the frequency of the reflected signal changes. The sensor detects the changed frequency and triggers the alarm. Every time the DWA system is armed, the sensor adapts to whatever objects might be stationary in the interior. This al- lows pacltages or objects to be left inside tlie car without ef- fecting the operation of the system. The sensitivity of the sensor is set so that the moving object must be at least as large as a bumble bee. This prevents a false alarm from oc- curring if a small insect is caught in the vehicle. FIS is switched off when the vehicle is locked two times within ten seconds. The DWA LED will flash one time for confirma- tion. This allows the sensor to be switched off to avoid false alarms when the windows are left open for venting.
51 5-26 Central Locking and Anti-Theft Interior sensor UIS (2000 and later models) The UIS system uses ultrasonic sound waves instead of elec- tromagnetic waves. Ultrasonic sound waves are less suscep- tible to magnetic interference. Every time the DWA system is armed, the sensor adapts to whatever objects might be stationary in the interior. The sen- sor emits ultrasonic waves in a programmed timed cycle. It re- ceives echoes of the emitted waves. The UIS amplifies the received sound wave signals and compares them to the ech- oes of the transmitted waves. The UIS also checits the incom- ing echoes for background hiss (wind noise through a partially open window) and adapts for this. If the echoes are consistently similar, no movement is de- tected. If the echoes are altered, (inconsistent), the UIS deter- mines motion in the interior compartment. If motion is detected, the UIS changes to a constant cycle and the echo is compared again. If the inconsistency is still present the UIS sends the acti- vate siren signal to the GM. Glass breakage sensors The doorwindows are monitored by inductive sensors mount- ed on the inside of the door behind the trim panel. A closed window is recognized by a magnetic plate on the glass lining up with the sensor. If the glass is broken, the plate falls away and the signal from the sensor changes. This causes the GM to activate the alarm. Emergency disarming - An emergency procedure is provided to cancel the DWA in the event that a fault occurs within the system. The procedure is as follows: Drivers door mechanically unloclted and open within 30 seconds. This will cause triggering of alarm. All doors closed. Ignition switch turned to KL R (ACCESSORY). LED indica- tor will come on. - After 10 minutes, alarm is disarmed
