screws may be used to the specified torques.

11. All mating connectors are to be appropriately

aligned prior to fitment back into the vehicle.

Check that white housing of the main Audio

Self-aligning connector (vehicle-side) is reset

outwards (by pulling the white connector

block rearwards in the car) prior to loading of

the ICC into the Instrument Panel. Failure to

do so may result in permanent damage to both

the vehicle-side connector and the Audio

Module.

DIAGNOSIS AND TESTING (Continued)

Daisy CAN Wiring Layout

Satellite Navigation control is via the infrared receiver

above the colour screen. It is wired directly to the Sat

Nav module and does not have any interface to the

audio module. The video signal also goes directly to

the colour screen. When the Sat Nav module display

is switched on, a video select line is grounded

between the Sat Nav Module and the Screen module.

This then runs the Sat Nav Video as the back ground

display on the screen and the ICC function become

pop up overlays.
The Cabin Temperature Sensor and remote key

receiver antenna are also directly wired to the BEM

and have no connection to the Audio Module.

If the ICC is replaced, the CTS calibration factor

needs to be retaught to the BEM (refer to section

419-10). The ICC/Audio Security Module

Reconfiguration will be required. WDS must be used

for this operation.
