This Service Information bulletin supersedes the orange Service Information bulletin number 65 09 91 (3344) dated September 1991. Additional vehicles are affected. Please remove and discard orange Service Information bulletin number 65 09 91 (3344) dated September 1991 from your S.I. binder.
SUBJECT:
Malfunction in Check Control Display or Telephone/Radio Information Flashing
MODELS:
1992 MY 735i, 735iL from 7/91 Production
1992 MY E34
1993 MY E34 (535i)
Situation:
Display on dashboard does not display "KEY IN IGNITION" message, or an invalid "CHECK CONTROL" message is displayed. In other cases, customer requests installation of BMW (Motorola) telephone. The Check Control Display on the dashboard flashes back and forth between the radio information and the telephone information.
Note:
This Service Information was superseded because an additional 500 Pioneer radios installed in '93 MY 535i vehicles were found to exhibit this problem. For all affected vehicles, the following procedure is necessary if the customer requests installation of the BMW (Motorola) telephone, and the radio information flashes during use of the telephone. Affected '93 MY 535i radios can be identified by a "535i ONLY" decal on the side of the radio. However, do NOT proceed with any repairs unless a customer complaint is experienced.
Solution:
PLAN A:
1. Remove radio from instrument panel.
2. Locate 2-pin connector between radio and harness and disconnect. See Figure # 1. If the connector cannot be located, or access limitations prevent disconnection, proceed with "PLAN B."
PLAN B:
1. Remove the large locking pin from the radio 17-pin connector (18126).
2. Insert two small drivers into the latch holes and slide the lock plate toward the CD data cable. This should release the plate.
3. Remove PIN # 7 and PIN # 17 with the terminal removal tool.
4. Slide the lock plate back into position.
5. Cover wire ends # 7 and # 17 with heat shrink tubing to insulate, and tiewrap loose ends to harness.
