Aplica-se a: MBS3 (MBS)
O que significa o código de avaria Scania MBS 543?
The fault is validated as present if the ECU does not detect communication on CAN bus 3 within the timeout period
O que causa o DTC 543 da Scania?
• Defect wiring for CAN bus 3. • Defect ECU unit(s) on CAN bus 3.
Como reage o sistema?
Functions dependent on information from CAN bus 3 are degraded/missing in MBS (Master)
Quais são os sintomas?
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.
Como resolver o código de avaria Scania MBS 543?
- Trouble shoot CAN bus 3 cable harness and connectors.
- Check connector for CAN bus 3 on MBS
- Check wiring for CAN bus 3:
- Measure the resistance (with the battery disconnected) between CAN-high and CAN-low.
- It should be close to 60 ohm (one 120 ohm termination resistor in each end of the CAN-bus).
- Measure the resistance (with the battery disconnected) between CAN-high on MBSM and CAN-high on any other unit on CAN bus 3.
- It should be close to zero ohm.
- Measure the resistance (with the battery disconnected) between CAN-low on MBS and CAN-low on any other unit on CAN-bus 3.
- It should be close to zero ohm.
