MODEL 220

Fig 1: Search Illumination Function Diagram

Interlinkage of components

The following lights are switched on and off under the same conditions:

Front ashtray illumination (E9/7)
Illumination for front cigar lighter (R3e1)
Left rear ashtray illumination (E9/8)
Right rear ashtray illumination (E9/9)
Stowage compartment illumination (E13/3)
Eyeglasses compartment illumination (E13/4)
Right front footwell lamp (E17/15)
Left front footwell lamp (E17/16)
Right rear footwell lamp (E17/17)
Left rear footwell lamp (E17/18)

Switching on lights

By manually switching on the parking and driving lights with the exterior lamp switch (S1) or
Automatically when the automatic driving light delayed switch-off feature is activated and night is recognized.

Switching off lights

Switch-off is accomplished immediately when the above requirements are no longer fulfilled or when the voltage is too low or too high.

Actuation of rear ashtray illumination

Actuation of the left rear ashtray illumination (E9/8) and right rear ashtray illumination (E9/9) is accomplished with pulse width modulation via the corresponding door control modules (N69/3, N69/4). The door control modules actuate the lights with the on/off ratio predefined by the instrument cluster (A1).

Required data:

Status c. 58d on instrument cluster (A1)

Actuation of remaining lights

Actuation of the lights is accomplished via the right front SAM control module (N10/7) except for the rear ashtray illumination (E9/8, E9/9).

The control module actuates the lights as soon as it receives the CAN message on/off ratio c. 58d > 5 % from the instrument cluster (A1). The lights cannot be dimmed.

Required data:

Status c. 58d on instrument cluster (A1)

With the exception of the illumination for front cigar lighter (R3e1) and the rear ashtray illumination (E9/8, E9/9) illumination is accomplished via diodes.
Only the left rear ashtray illumination (E9/8) and right rear ashtray illumination (E9/9) are dimmable in addition to the switch illumination. The setting is accomplished via the brightness control for the instrument and search illumination rheostat (A1r1).
