Temperature-Controlled Cup Holder, Function - GF68.00-P-0001GN
MODEL 166 as of model year 2016 with CODE 311 (Temperature-controlled cup holder)
MODEL 292 with CODE 311 (Temperature-controlled cup holder)
Function requirements, general
- Circuit 15R ON
The electronic ignition lock control unit transmits the circuit 15 status via the interior CAN to the SAM control unit.
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:
- Residual heat indicator lamp
- Cup holder button
- Heating/cooling element (Peltier element)
- Fan
- Temperature sensor
- Electronic control
The cup holder is supplied with voltage when circuit 15R is switched on over relay circuit 15R1 in the rear fuse box.
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 takes places within the following time-dependent cooling output for a 0.33 l beverage can as an 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 takes places within the following time-dependent heating output for a 0.33 l beverage can as an 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, 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 inhibited.
- Flashing three times:
Malfunction in cupholder heating/cooling element. Disconnect cup holder from on-board electrical system and reconnect. If the error occurs again, the heating/cooling system 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.
