Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-B110114

Condition
The Central electronic module (CEM) checks the output signal to the relay coil for relay, comfort.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Signal too low from the output.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Activated relay.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.

This diagnostic trouble code (DTC) is never stored on its own.

Substitute value
- The function switches off permanently after 100 operating cycles where the fault was detected. Erasing diagnostic trouble codes (DTCs) resets the result.

Possible source
- Damaged relay.
- Short-circuit to ground in the relay driver circuit.
- Open-circuit in the relay coil.

Fault symptom[s]
- Air flow problem
- No recirculation
- Poor air quality in the passenger compartment
- Battery discharges
