Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-B10BE13

Condition
The central electronic module (CEM) checks the signal from the sun sensor.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Direct current (DC) from the sun sensor is higher than 4.85 V.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position I and II.

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.

Substitute value
- None.

Possible source
- Open circuit on signal cable.
- Damaged sun sensor.

Fault symptom[s]
- Cabin temperature does not decrease with high sun intensity
- Cabin temperature does not correspond to value set
