01044
From Ross-Tech Wiki
01044 - Control Module Incorrectly Coded
Possible Symptoms
- Reduced Functionality
Possible Causes
- Control Module incorrectly coded
Possible Solutions
- Check Gateway Installation List
- Check/Fix Control Module Coding
- See Vehicle Specific Diagnostic Procedures for Details
Special Notes
- When found in CAN-Gateway:
- On a Long Coded module, use the Gateway Installation List to check for unreachable or not registered control modules. Then update the Gateway [Installation List] by altering the Gateway Coding manually.
- On a Short Coded modules, refresh the original coding with the same value. For example, code it from 00006 -to- 00006 without making an actual change.
- When found in VW New Beetle/Cabriolet (1C/1Y/9C): Comfort System, this may be a Bug in the Control Module Software that will be resolved by refreshing the Coding with the same Value as described above with the CAN Gateway example.
- When found in Brake Electronics (MK60EC1) while the Coding is NOT all Zeros, check the [19-CAN Gateway] > [Coding - 07]. An incorrect LHD/RHD Configuration may cause this Fault Code.
- When found in the VW Passat (3B) Gateway Controller: Vehicles built through January 2000, the Gateway Software did not take in account for the ABS Controller. This fault code should be ignored. New Software was implemented after February 2000 that eliminated this fault code, however the coding should not be changed to add the ABS controller.
01044 - Control Module Incorrectly Coded: Implausible Signal
Possible Symptoms
- Reduced Functionality
- Malfunction Indicator Light (MIL) active
Possible Causes
- Control Module incorrectly coded
Possible Solutions
- Check/Fix Control Module Coding
- See Vehicle Specific Diagnostic Procedures for Details
Special Notes
- Some Passat (3B/B5) around MY 2000 have a Firmware Bug which causes this DTC to be set in the CAN Gateway (19). Service Documents for of those Cars indicate that this DTC should be ignored in that Module as long as the Coding matches the Vehicle Equipment.
