Bluetooth test with the (IMIB) Integrated Measurement Interface BoxR2

Using the Integrated Measurement Interface Box R2 (IMIB) it is possible to perform an independent Bluetooth test of the vehicle components. The IMIB acts in a similar way to a mobile phone, and can be connected to the vehicle to checked in this way. Please refer to the operating instructions of the vehicle for the procedure for establishing a Bluetooth connection to the vehicle, also known as Bluetooth pairing.

NOTE: The result of the Bluetooth test, as an independent version on the IMIB, is not taken over into the diagnosis report. The Bluetooth test is to be used as an additional tool for the diagnosis on the vehicle. If the test is not completed successfully, a vehicle diagnosis must be performed using the diagnosis system! Warranty-related invoicing can only take place after a full diagnosis has taken place.

The following general conditions must be taken into account in order to be able to successfully carry out the Bluetooth test.

The latest software must be installed on the IMIB.
Battery charger connected.
Ignition turned on.
Perform Bluetooth test with the IMIB on the driver's seat.
Determine the Bluetooth passkey if necessary.
NOTE: The Bluetooth passkey to be used can be found in the vehicle documentation or on the label on the telephone control unit for vehicles E46, E83, E53, E85, E86, E65, E66, E67, E68 and RR1, RR2, RR3 (depending on equipment). This can additionally be read out via the control unit functions of the telephone control unit.
The examples listed in the description refer only to connections with BMW vehicles. The system behaves identically for vehicles of the type MINI or Rolls-Royce.

The Integrated Measurement Interface Box R2 (IMIB) also supports the SSP (Secure Simple Pairing) connection type. Step 5 will look at this connection option in more detail.

Proceed as follows to perform the Bluetooth test:

Step 1 (Preparing the IMIB)

In the IMIB main menu, select the bottom right menu item and then the < Bluetooth test > menu item.

2	Comment field

NOTE: First of all, the hardware addresses of the Bluetooth devices found are displayed. A built-in filter ensures that only vehicles are found. A connection to other devices is not possible.
The green information bar shows the progress of the search.
Device addresses can be present multiple times in this list.
After the search has been completed, the names of the vehicles with which the IMIB can be paired are displayed.
The complete search process can take up to 30 seconds.
If devices are found, these will be shown as described in point 4.

NOTE: Found vehicles respond to the IMIB with their name (brand) and number (the last 5 digits of the vehicle identification number).
Examples:

BMW 17881
MINI 36617
RR 32002

If no devices with a corresponding identification were found, this is shown on the IMIB display and the selection window remains empty.

In this case, repeat the search for the Bluetooth device up to five times as described in step 3.

Step 4 (Selecting the vehicle and connecting)

Select the vehicle to be connected from the list. Then press < Connect >.

NOTE: A connection can only be established from the IMIB to the vehicle, not the other way around.

Enter Bluetooth passkey on the IMIB. Example: 9876

To enter the Bluetooth passkey on the IMIB, activate the input box on the display. Enter the Bluetooth passkey using the input keys on the left or the IMIB display keyboard.

Press < Sending PIN > to confirm.

Enter the Bluetooth passkey in the vehicle and confirm with < OK >. The Bluetooth passkey must be entered and confirmed in the vehicle within 30 seconds.

NOTE: The Bluetooth passkey must not contain more than 4 digits for the test. (example on a F01 with Combox.)

NOTE: Vehicle E46, E83, E53, E85, E86, E65, E66, E67, E68 and RR1, RR2, RR3 (depending on equipment) are equipped with a fixed Bluetooth passkey. For the vehicles the entry of the Bluetooth passkey in the vehicle is dispensed with. The Bluetooth passkey to be used is found in the vehicle documentation or on the label on the control unit. This can additionally be read out via the control unit functions of the telephone control unit.

Step 5 (For SSP only - Secure Simple Pairing)

Select the vehicle to be connected from the list. Then press < Connect >.

A Bluetooth passkey is shown on the IMIB display. The same Bluetooth passkey must be shown in the vehicle. If the two numbers match, press < OK > in the vehicle to confirm.

NOTE: The device name of the IMIB is: IMIB XXXXX (XXXXX = serial number of IMIB)
If the device name of the IMIB is shown in the list of connected Bluetooth devices on the vehicle's control display (if available), then the Bluetooth functionality is OK. The Bluetooth components in the vehicle are working properly.

NOTE: If the Bluetooth test was not successful, carry out the test again with the IMIB held close to the Bluetooth control unit (ULF, TCU, Combox, headunit or radio, depending on vehicle equipment). If the vehicle is found when the Bluetooth test is performed near the control unit, then the fault is most likely due to the Bluetooth antenna cable connector on the control unit. In this case, continue the troubleshooting there.

Important Limited connection time!

In the case of a timeout during while establishing a connection or transmitting the Bluetooth passkey, the connection is automatically interrupted after approx. 30 seconds. A message then appears on the IMIB display.

Step 7 (Terminating a connection)

Press < Disconnect > to terminate the connection.

Step 8 (Deleting the IMIB from the vehicle)

After completing the Bluetooth test, the IMIB must still be deleted as a paired Bluetooth device from the vehicle list. Otherwise an extra Bluetooth device will be stored in the vehicle memory unnecessarily. Refer to the vehicle operating instructions for this function.
