MBS MBS kontrol ünitesi · Scania

Kod 543 (ondalık). Bazı teşhis cihazları bunu onaltılık olarak 021F şeklinde gösterir.

Kısaca

The fault is validated as present if the ECU does not detect communication on CAN bus 3 within the timeout period

Uygulandığı yer: MBS3 (MBS)

Scania MBS arıza kodu 543 ne anlama gelir?

The fault is validated as present if the ECU does not detect communication on CAN bus 3 within the timeout period

Scania DTC 543 kodunun nedeni nedir?

• Defect wiring for CAN bus 3. • Defect ECU unit(s) on CAN bus 3.

Sistem nasıl tepki verir?

Functions dependent on information from CAN bus 3 are degraded/missing in MBS (Master)

Belirtiler nelerdir?

MBS expansion node J, K, L and M are connected to CAN bus 3, meaning that components connected to those nodes may not work as intended.

Scania MBS arıza kodu 543 nasıl giderilir?

  1. Trouble shoot CAN bus 3 cable harness and connectors.
  2. Check connector for CAN bus 3 on MBS
  3. Check wiring for CAN bus 3:
  4. Measure the resistance (with the battery disconnected) between CAN-high and CAN-low.
  5. It should be close to 60 ohm (one 120 ohm termination resistor in each end of the CAN-bus).
  6. Measure the resistance (with the battery disconnected) between CAN-high on MBSM and CAN-high on any other unit on CAN bus 3.
  7. It should be close to zero ohm.
  8. Measure the resistance (with the battery disconnected) between CAN-low on MBS and CAN-low on any other unit on CAN-bus 3.
  9. It should be close to zero ohm.
