BMW Accessory Navigation System Speed Input Signal (84 08 00)

BMW ACCESSORY NAVIGATION SYSTEM SPEED INPUT SIGNAL

TECHNICAL SERVICE BULLETIN

SUBJECT

E39 - BMW Accessory Navigation System Speed Input Signal

SITUATION

During the installation of the BMW Accessory Navigation System into E39 vehicles, the speed signal input (male pin # 3 in the connector X322) cannot be found.

CAUSE

Since July of 1999 production, the separate speed signal (Speed-A) output harness has been eliminated from series production. The speed information is now made available to the connected control modules in the form of a telegram via the body bus (K-bus). By design, the Accessory Navigation System is not capable to extract speed signal information from the K-Bus.

CORRECTION

When installing the BMW Accessory Navigation System into E39 vehicles manufactured after 06/99, the Speed-A signal wire has to be fitted between the instrument cluster (pin # 3 of the 18-pin connector X10113 for the IKE, or pin # 14 of the 26-pin connector X11176 for the Kombi) and pin number 3 of the X322 connector (located in the rear left corner of the trunk).

Such a modification is not covered by the BMW New Car Limited Warranty.

PROCEDURE

For the Speed-A signal adapter harness use one of the wires from the Airbag Repair Cable (P/N 61 12 8 386 368) and the male socket connector P/N 61 13 0 007 452.

1. Cut through the single wire from the Airbag Repair Harness, at the length of 12 feet, starting from the female Siemens connector. See Fig 2 .
   Fig 2: Cutting Airbag Repair Harness Wire

   
2. Strip off insulation at the end of the cut wire (stripped length 4.5 mm), and crimp the male socket connector P/N 61 13 0 007 452. See Fig 3 . Use the appropriate crimping tool e.g. pliers with die block P/N 61 9 041 found in the Electric Repair Kit IV P/N 61 9 020.

3. Remove the instrument cluster. Refer to Repair Manual RA 62 11 200.

   Find connector (1, Fig 4 ):

   • X10113 (18-pin natural) on vehicles with IKE, or
   • X11176 (26-pin natural) on vehicles with low cluster

4. Disassemble the connector by removing the locking tab (sliding it upwards), and then removing the housing assembly as shown in Fig 5 .

5. Insert female Siemens connector of the adapter harness into the slot number:
   • 3 of connector X10113 (IKE), or
   • 14 of connector X11176 (Kombi).
