Supply currents too high
- Check connected components, cable harness and connectors for mechanical damage. - Check that no components have been connected except such included in the door system from the factory. - If the system checks out all right and the DTC is set repeatedly it could be due to internal faults in the DCU, contact Scania Global Technical Support for advice.
What you'll see
- Limited door functionality or complete loss of some functions depending on how many of the power rails or low-side outputs that are affected. - One or more fuse is blown.
System reaction

Diagnostic depth
The DCU has detected that currents supplied to the DCU power connections or drained by low-side outputs on the DCU have exceeded the following limits for >5 s: V1: 20 A V2: 20 A V3: 20 A Total supplied current (V1+V2+V3): 30 A Total drained current (all low-side outputs): 18 A
- Actuators conncted to the DCU have higher power consumption than expected due to component faults, for example. - Additional unapproved components could have been connected to the DCU. - Hardware failure..
