Variant 1
Applies to: COO10 (COO)
What does Scania COO fault code 847 mean?
The coordinator has identified divergent information from the CMS control unit.
What causes Scania DTC 847?
The fault may be due to: - The CMS control unit may be misconfigured or not programmed. - The coordinator may be misconfigured or not programmed.
How does the system react?
Red warning indication of a coordinator fault is displayed.
What are the symptoms?
Operational data cannot be saved while the fault is active.
How to fix Scania COO fault code 847?
- Check whether the CMS control unit or the coordinator has an incorrect chassis serial number.
- If so, carry out spare part programming on the control unit with anomalous software.
Variant 2
Applies to: COO11 (COO)
Detection
The coordinator has identified divergent information from the CMS control unit.
Possible cause
The fault may be due to: - The CMS control unit may be misconfigured or not programmed. - The coordinator may be misconfigured or not programmed.
Symptoms
Operational data cannot be saved while the fault is active.
How to fix
- Check whether the CMS control unit or coordinator has an incorrect chassis serial number.
- If so, carry out spare part programming on the control unit with deviating software.
Variant 3
Applies to: COO8 (COO)
Detection
The coordinator has identified divergent information from the CMS control unit.
Possible cause
The fault may be due to: - The CMS control unit may be incorrectly set or not programmed. - The coordinator may be incorrectly set or not programmed.
Symptoms
Operational data cannot be saved while the fault is active.
How to fix
- Check whether the CMS control unit or the coordinator has an incorrect chassis serial number.
- If so, carry out spare part programming on the control unit with anomalous software.
Variant 4
Applies to: COO9 (COO)
Detection
The coordinator has identified divergent information from the CMS control unit.
Possible cause
The fault may be due to: - The CMS control unit may be incorrectly set or not programmed. - The coordinator may be incorrectly set or not programmed.
Symptoms
Operational data cannot be saved while the fault is active.
How to fix
- Check whether the CMS control unit or the coordinator has an incorrect chassis serial number.
- If so, carry out spare parts programming of the incorrectly programmed control unit.
Variant 5
Applies to: COO8
Detection
The coordinator has identified divergent information from the CMS control unit.
Possible cause
The fault may be due to: - The CMS control unit may be incorrectly set or not programmed. - The coordinator may be incorrectly set or not programmed.
System reaction
The symbol for a serious general system malfunction comes on in the instrument cluster. Operational data cannot be saved while the fault is active.
How to fix
- Use SDP3 to check whether the CMS control unit or coordinator has an incorrect chassis serial number.
- If so, carry out spare parts programming of the incorrectly programmed control unit.
