GF54.30-P-2006GZ Activate Instrument Cluster, Function

Component Identification:

Activation of instrument cluster (A1)
Because it relies on black-screen technology, the details on the instrument cluster (A1) (e.g. displays, gauges, etc.) are clearly visible only when the instrument cluster (A1) has been activated. If the instrument cluster (A1) is activated, the current contents are shown in the displays and the illumination of the instrument (A1) is switched on as well as the fuel reserve indicator lamp (A1e4) actuated.

The instrument cluster is activated by switching on "circuit 15g"A1. After "circuit 15g" is switched off the instrument cluster (A1) remains active for a further 30 seconds, but can be extended up to 2 minutes in the event of the occurrence of active warnings. The instrument cluster is activated with "circuit 15g OFF" A1 under the following conditions:
^ The instrument cluster is activated for 30 seconds by the instrument and controls illumination button, dim (A1s5) or instrument and controls illumination button, bright (A1s4) and trip odometer reset button (A1s3)A1).
^ The instrument cluster is activated for 30 seconds when the driver's door is opened or closedA1.
^ When the standing lamp or driving lamps are switched on, the instrument cluster (A1) remains in operation for as long as the standing lamp is switched on.

If one of the stated conditions occurs whilst the instrument cluster (A1) is already active, then the instrument cluster (A1) remains activated for a further 30 seconds from this point in time.

Networking
The status of the left front door rotary tumbler microswitch (M14/6s1) is read in by the rear SAM control unit (N10/8) and placed as a CAN message on the CAN interior.

The status of the standing lamp (ON/OFF) is placed on the CAN interior by the front SAM control unit (N10).
