Diagnostic Trouble Code (DTC) Information

Condition




Climate control module (CCM) checks the internal memory handling in the control module's processor.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Processor in the Climate control module (CCM) uses more memory space than what is allotted.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position I and II.

Note! In case of this problem, DTC CEM-DE29 may also be generated. Fault-trace this diagnostic trouble code (DTC) first.

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.
