Switch Functions, Dashboard Environment Panel, (Lower Section)

The following functions can be activated using the switches on the dashboard environment panel:
- Folding head restraint, rear seat (S60/S80).
- Folding door mirrors (market dependent).
- Bi-fuel, on / off (market dependent).
- Valet lock, on/off.
- Child lock, on / off (market dependent).
- STC, off / on (option).
- DSTC, off / on (option).
- Auxiliary lamps, off / on (option).
- Reduced alarm, on / off (option).

In order for certain functions to be activated the engine must be switched on and/or the master key must be in position II.

Folding head restraints, rear seat

When the switch for the folding head restraints is activated, information is transmitted by the climate control module (CCM) (3/112) to the rear electrical module (4/58) via the Controller area network (CAN).

For further information, see Design and Function, rear electronic module (REM).

Folding door mirrors

When the switch for the folding door mirrors is activated, information is transmitted by the climate control module (CCM) to the driver's door module (3/126) and the passenger door module (PDM) (3/127) via the Controller area network (CAN).

For further information, see Design and Function, passenger door module (PDM) / driver's door module.

Bi-fuel

When the bi-fuel switch is activated, a signal is transmitted from the climate control module (CCM) to the engine control module (ECM) (4/46) on the Controller area network (CAN) via the central electronic module (CEM). The engine control module (ECM) transmits a signal to the climate control module (CCM) about the type of fuel being used. The climate control module (CCM) uses this signal to light / turn off the LED on the switch.

For further information, see Design and Function, engine control module (ECM).

Hint: This section will first be accessible during 2003.

Valet lock / child-proof lock

When activating the valet lock switch or the child lock switch information is transmitted to the rear electronic module (REM) via the Controller area network (CAN).

For further information, see Design and Function, Central locking.

STC or DSTC

When the STC or DSTC switch is activated, a signal is transmitted from the climate control module (CCM) to the brake control module (BCM) (previously ABS) (4/16) via the Controller area network (CAN). The brake control module (BCM) transmits a signal to the climate control module (CCM) about whether the STC or DSTC functions are operating. The climate control module (CCM) uses this signal to light / turn off the LED on the switch.

For further information, see Design and Function, Brake system.

Auxiliary lamps

When the auxiliary lamps switch is activated, information is transmitted from the climate control module (CCM) to the central electronic module (CEM). The central electronic module (CEM transmits a signal to the climate control module (CCM) about whether the auxiliary lamps are on or not. The climate control module (CCM) uses this information to light / turn off the LED on the switch.

For further information, see Design and Function, central electronic module (CEM).

Reduced alarm

When activating the reduced alarm switch information is transmitted via the Controller area network (CAN) to the upper electronic module (UEM) and rear electronic module (REM).

For further information, see Design and Function, Alarm.

Rear A/C

When activating the switch for rear A/C information is transmitted via the Controller area network (CAN) to the rear electronic module (REM). From this signal and the signal from the engine control module (ECM) indicating whether the engine is running or not, the rear electronic module (REM) will activate/deactivate the relay supply to the rear A/C system. The rear electronic module (REM) transmits a signal indicating whether the rear A/C is on or not to the climate control module (CCM) via the control area network (CAN).

The climate control module (CCM) uses this information to light / turn off the LED in the switch.
