Variant 1
Applies to: COO8 (COO)COO9 (COO)
What does Scania COO fault code 590 mean?
The coordinator has identified divergent information from the ICL control unit.
What causes Scania DTC 590?
The fault may be due to: - The ICL control unit may be incorrectly set or not programmed. - The coordinator may be incorrectly set or not programmed.
What are the symptoms?
- The operational data cannot be saved as long as the fault code is active. - The vehicle may display unexpected behaviour if a control unit is incorrectly configured.
How to fix Scania COO fault code 590?
- Check whether the instrument cluster 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: COO10 (COO)
Detection
The coordinator has identified divergent information from the ICL control unit.
Possible cause
The fault may be due to: - The ICL control unit may be misconfigured or not programmed. - The coordinator may be misconfigured or not programmed.
System reaction
Red warning indication of a coordinator fault is displayed.
Symptoms
- Operational data cannot be saved as long as the fault code is active. - The vehicle may behave unexpectedly if a control unit is misconfigured.
How to fix
- Check whether the instrument cluster or the coordinator has an incorrect chassis serial number.
- If so, carry out spare part programming on the control unit with anomalous software.
Variant 3: DDU control unit
Applies to: COO11 (COO)
Detection
The coordinator has identified anomalous information from the DDU control unit.
Possible cause
- The DDU control unit may be incorrectly set or not programmed. - The coordinator may be misconfigured or not programmed.
Symptoms
- Operational data cannot be saved as long as the fault code is active. - The vehicle may behave unexpectedly if a control unit is misconfigured.
How to fix
- Check whether the DDU 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 4
Applies to: COO7
Detection
The coordinator has identified divergent information from the ICL control unit.
Possible cause
The fault may be due to: - The ICL 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.
How to fix
- Use SDP3 to check whether the ICL control unit has a divergent chassis serial number.
- If so carry out spare parts programming of the control unit.
- Tip:If only one control unit seems to be faulty, carry out spare parts programming of the faulty control unit.
- If several control units seem to be faulty, carry out spare parts programming of the coordinator.
Variant 5
Applies to: COO8
Detection
The coordinator has identified divergent information from the ICL control unit.
Possible cause
The fault may be due to: - The ICL 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.
How to fix
- Use SDP3 to check whether the instrument cluster or coordinator has an incorrect chassis serial number.
- If so, carry out spare parts programming of the incorrectly programmed control unit.
