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.
Substitute Value
- None.
Possible Source
- Faulty outside temperature sensor.
- Fault-trace in transmitting control module.
Fault symptom[s]
