- Separating one user from the connector strip X30/5 (Left voltage distributor (CAN) connector)
- Observe level voltage.
- Plug in connector again at connector strip X30/5 (Left voltage distributor (CAN) connector).
- Repeat this procedure for all CAN users.
Specified value
- As soon as the faulty branch was disconnected, the current image of the level voltage changes.
Possible cause of fault in the faulty branch
- X30/5 (Left voltage distributor (CAN) connector)
- Test connectors and wiring for CAN of engine compartment CAN control modules.
- Control unit
Communication with ECU required ( Measuring system )

Important notes
- When CAN diagnosis is finished, the 8-pin CAN cable must be replaced with the diagnostic cable.
- Before values are read out from a control unit, the control unit must be reinitialized.
