Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information HCM-U040181

Condition
The control module is continuously supplied with information about current outdoor temperature from Engine control module (ECM) via CAN-communication. The control module checks the quality of the information from the Engine control module (ECM).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Information from Engine control module (ECM) is incorrect/unreasonable.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position 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.

- Faulty outside temperature sensor.
- Fault-trace in transmitting control module.
