  3. Damper motor module (DMM) recirculation.
  4. Seat heating module (SHM), front left only applies if there is no seat heating module (SHM) ventilation.
  5. Seat heating module (SHM), left ventilation option/accessory
  6. Seat heating module (SHM), rear left option/accessory
  7. Switch, rear seat heating. Option/accessory

The diagnostic trouble code (DTC) is stored if the control module detects that

  1. Received message does not correspond with expected message.

The control module's test for the diagnostic trouble code (DTC) starts in the event of

  1. Ignition switch position II.

Substitute Value

  1. None.

Possible Source

  1. Communication interference.
  2. There are two master nodes in LIN bus A.

Fault symptom[s]

  1. Air flow problem
  2. No recirculation
  3. Temperature control/Uneven temperature
  4. Poor heating in compartment
  5. Front seat heating does not operate
  6. Rear seat heating does not operate

Condition

Climate control module (CCM) both sends and receives information via standardized serial communication - LIN (Local Interconnect Network). Climate control module (CCM) checks the status of LIN-bus 1. The following components communicate on LIN bus 1

  1. Damper motor module (DMM) air distribution.
  2. Damper motor module (DMM) temperature left.
  3. Damper motor module (DMM) recirculation.
  4. Seat heating module (SHM), front left only applies if there is no seat heating module (SHM) ventilation.
  5. Seat heating module (SHM), left ventilation option/accessory
  6. Seat heating module (SHM), rear left option/accessory
  7. Switch, rear seat heating. Option/accessory
