Variant 1
Applies to: BCI1 (BWE)BCI2 (BWE)
What does Scania BCI fault code 572 mean?
Excess current or short circuit to ground or supply voltage.
What causes Scania DTC 572?
The cause can be one of the following: - Fault in connections or cable harness. - Short circuit to ground or supply voltage. - Incorrect electrical load.
How does the system react?
A yellow warning indication is displayed. Bodywork functions that rely on logic diagrams using this output do not function correctly as long as the fault code is active.
How to fix Scania BCI fault code 572?
- Use BICT to find out which bodywork functions are connected to the output.
- Check the connections, cable harnesses and components connected to the input.
