Keyless Entry Transmitter: Testing and Inspection
INITIALIZATION OF THE TRANSMITTERS TO THE RECEIVER1. Enter the vehicle and shut all doors.
2. Turn ignition switch to the Accessory position (KL R), and then turn it off again within 5 seconds.
3. Holding the transmitter near the mirror, depress and hold down the unlock button (button with the up arrow marking).
4. While holding down the unlock button, depress and release the lock button (button with the BMW logo) three times (within 10 seconds of depressing the unlock button).
5. Release the unlock button and continue to hold the transmitter near the mirror until the LED on the transmitter quits flashing.
6. Without turning the ignition on again, repeat steps 3 through 5 for additional transmitters (up to four transmitters can be initialized to one receiver).
Confirmation of initialization is recognized by the door lock buttons being activated (to lock position, then immediately back to the unlock position) when the lock button of the remote control transmitter is released during the initialization procedure (see steps of the procedure).
If this lock activation does not take place as described, initialization has not occurred. This may be due to improper initialization procedures, or due to an "initialization block" being present in the receiver.
Initialization can be "blocked," as a security measure, under two circumstances:
- if the transceiver loses its initialization (failed transmitter) while the DWA is armed, or
- if the mirror is removed while the DWA is armed
The initialization block is also active whenever the vehicle is locked to prevent any other transmitter from being initialized to the receiver.
If a vehicle is encountered with an initialization block, remove the block using the following procedure.
Procedure:
Using the DIS Tester:
1. Select "Diagnostics"
2. Select Vehicle (e.g., "5" E34") and "Diagnosis"
3. Select "12 Radio/IR System"
4. Select "5 Special Functions"
5. Select "2 Cancel Initialization Lock"
