BCI BCI control unit · Scania · 5 variants

Code 517 (decimal). Some diagnostic tools show it in hexadecimal as 0205.

In short

The expansion unit has lost stored operational data.

Variant 1

Applies to: BCI B1 (BWEXBUS)BCI E1 (BWEXA)BCI E1 (BWEXB)BCI E1 (BWEXC)BCI E1 (BWEXD)BCI E1 (BWEXE)BCI E1 (BWEXF)BCI E1 (BWEXG)BCI E1 (BWEXH)BCI E1 (BWEXI)

What does Scania BCI fault code 517 mean?

The expansion unit has lost stored operational data.

What causes Scania DTC 517?

Expansion unit supply voltage was disconnected when storing data.

How does the system react?

Locally stored operational data has been lost and cannot be recreated.

How to fix Scania BCI fault code 517?

  1. No action, since lost data cannot be recreated.
  2. However, the expansion unit is functional and new data can still be saved.

Variant 2

Applies to: BCI1 (BWE)BCI2 (BWE)

Detection

The control unit has lost stored operational data.

Possible cause

Control unit supply voltage was disconnected when storing data.

System reaction

Locally stored operational data has been lost and cannot be recreated.

How to fix

  1. No action, because lost data cannot be recreated.
  2. However, the control unit is functional and new data can still be saved.

Variant 3

Applies to: BCI2 (BWE)

Detection

The control unit has lost stored operational data.

Possible cause

Control unit supply voltage was disconnected when storing data.

System reaction

Locally stored operational data has been lost and cannot be recreated.

How to fix

  1. No action, because lost data cannot be recreated.
  2. However, the control unit is functional and new data can still be saved.

Variant 4

Applies to: BCI3 (BWE)

Detection

The control unit has lost stored operational data.

Possible cause

System supply voltage (U30, for truck) was cut off while the ECU was writing to the file containing operation data.System supply voltage (B+, for bus) was cut off while the ECU was writing to the file containing operation data.System supply voltage (U30, for truck) was cut off while the ECU was writing to the file containing operation data.
