SUBJECT:
CD Changer (Nakamichi or Alpine) Failure During Installation
MODEL:
E46, X5 with optional Alpine or Nakamichi CD Changer
Situation:
After connecting power supply to the CD changer during installation (directly to the unit in case of Alpine changer, or thought power/I-Bus
extension cable for Nakamichi units), changer remains inoperative. The changer's 3 Amp fuse (located in the back of a unit) is blown, and in some
cases a fuse for a phone system (F74 on X5 vehicles, or F39 for E46) is found to be defective as well.
Cause:
The 3-pin phone compensator connector (X1765) was mistakenly identified (and plugged into a changer) instead of a power/I-Bus (X18180)
connection. Both connectors have identical housing, and are located in the left rear trunk corner.
The compensator connector was introduced to the telephone wiring harness in preparation for a new digital cellular phone (CPT 7000).
Correction:
During installation before connecting harness to the CD changer, the black 3-pin CD power/I-Bus connector (X18180) has to be identified by
checking its wiring configuration:
-- Pin # 1 - Brown wire (ground)
-- Pin # 2 - Red wire (power)
-- Pin # 3 - White (or white with yellow/red tracer) wire (I-Bus)
The X18180 connector is located:
X5 CD and telephone harness location:
350
-- X5 vehicles: in the left rear quarter panel (behind the navigation computer bracket), attached to the audio/amplifier harness (see illustration S65
00 01)
-- E46 vehicles: at the floor of left rear quarter panel, attached to the CD 6-pin data cable.
Note:
For easier identification: the compensator connector (X1765) is always attached to the phone data/power wiring harness and can be found: on X5
vehicles near 26-pin "D"-sub connector, on E46 vehicles near 26-pin ELO connector.
