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-proof lock, on/off (market dependent)
• Rear air conditioning (A/C) (XC90, option)
• STC, off / on (option)
• DSTC, off / on (option)
• BLIS, off / on (option)
• Auxiliary lamps, off / on (option)
• Parking assistance (option)
• Reduced alarm, on / off (option)
• Four-C (Continuously Controlled Chassis Concept), (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 control area network (CAN).

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 door module (3/126) and the passenger door module (PDM) (3/127) via the control area network (CAN).

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 control area network (CAN) via the central electronic module (CEM) (4/56). 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 information to light and turn off the LED in the switch.

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 control area network (CAN).

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 and turn off the LED in the switch.

STC or DSTC  (applies to model year -2006)

When the STC or DSTC switch is activated, a signal is transmitted from the climate control module (CCM) to the brake control module (BCM) (4/16) via the controller area network (CAN). The brake control module (BCM) then transmits a signal to the climate control module (CCM) indicating that the STC or DSTC function is on or off. The climate control module (CCM) uses this information to light and turn off the LED in the switch.

BLIS  (applies to model year 2007-)

When activating the switch for Blind Spot Information System, the information is transmitted via the CAN network to the Driver door module (DDM) / Passenger door module (PDM). The Driver door module (DDM) / Passenger door module (PDM) transmit the signal to the Climate control module (CCM) about whether the BLIS function is on or off.

The Climate control module (CCM) uses the signal to switch the LED on or off the switch

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 and turn off the LED in the switch.

Back-up warning 

When activating the switch for parking assistance, information is transmitted via the Controller area network (CAN) to the rear electronic module (REM).

Reduced alarm 

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

Four-C (Continuously Controlled Chassis Concept) 

When activating the switch for Four-C, information is transmitted via the Controller area network (CAN) to the suspension module (SUM).
