What causes Scania DTC 1289?

- There may be an open circuit or poor contact in the cable harness for CAN to the affected control unit. - There may be an internal fault or a loss of power supply in the control unit concerned. - Electromagnetic interference may also be a cause.

How does the system react?

If the fault occurs there will be no standby function. The yellow warning symbol is on when the fault is active.

How to fix Scania ELC fault code 1289?

  1. Check whether more fault codes affecting the red CAN bus have been registered on other control units.
  2. If only the affected control unit does not respond, there are no electrical faults on the CAN bus.
  3. Check the control unit in question and its CAN cables for open circuits or poor contact.
  4. If the control unit is connected to a different CAN bus than ELC, this may indicate that this part of the CAN cable harness is faulty.
  5. Also check the coordinator's fault codes.
  6. Electromagnetic interference can, for example, occur due to an incorrectly connected mobile phone.
