Temperature-Controlled Cup Holder, Function - GF68.00-P-0001GR

MODEL 166 up to model year 2016 with CODE 311 (Temperature-controlled cup holder) 

Function requirements, general 

• Circuit 15R ON

Temperature-controlled cup holder, general 

Beverages can be cooled or heated with the cup holder. It is possible to heat to approx. T = 58 °C and cool to approx. T = 3 °C.

The main cup holder components are:

• Cup holder button
• Residual heat indicator lamp
• Heating/cooling module (Peltier element)
• Fan
• Temperature sensor

The cup holder is supplied with voltage when circuit 15R is switched on over relay circuit 15R1 in the rear fuse box.

The electronic ignition lock control unit sends the status of circuit 15 via interior CAN to the SAM control unit.

The cup holder function comprises the following partial functions:

• Function sequence for cooling 
• Function sequence for heating 
• Function sequence for display of fault messages 

Function sequence for cooling 

The cooling function is activated when the cup holder button is actuated once. Active cooling is indicated by a blue LED flashing. The cooling procedure has the following time-dependent cooling stages for a 0.33 I beverage can, for example:

• Within t = 30 min from T = 21 °C to approx. T = 15 °C
• Within t = 60 min from T = 21 °C to approx. T = 10 °C
• Within t = 120 min from T = 21 °C to approx. T = 5 °C

The cooling procedure can be interrupted when the LED on the cup holder button is pressed again before the LED goes out.

Function sequence for heating 

The heating function is activated when the cup holder button is pressed twice. Active heating is indicated by a red LED flashing. The heating procedure has the following time-dependent heating stages for a 0.33 l beverage can, for example:

• Within t = 30 min from T = 21 °C to approx. T = 30 °C
• Within t = 60 min from T = 21 °C to approx. T = 40 °C
• Within t = 120 min from T = 21 °C to approx. T = 50 °C

The residual heat indicator lamp signals increased temperature to the vehicle passengers starting at a temperature of approx. T = 40 °C.

The heating procedure can be interrupted when the LED on the cup holder button is pressed again before the LED goes out.

Function sequence for display of fault messages 

Errors occurring during operation are indicated by the corresponding LED flashing:

• Double flashing:

  The cup holder button is blocked.

• Flashing three times:

  Malfunction in cup holder heating/cooling module. Disconnect cup holder from on-board electrical system and reconnect.

  If the error occurs again, the heating/cooling module is defective.

• Flashing four times:

  Malfunction in cup holder temperature sensor. Disconnect cup holder from on-board electrical system and reconnect.

  If this error occurs again, the temperature sensor is defective.
