Communication with the slave coordinator
If communication with the engine control unit also has been interrupted (fault code 5100 has been set), carry out the following: Check the CAN bus circuit for open circuit or any misconnection.Measure the resistance between coordinator pin 45 and 21. Correct value should be 60 ohm.Check whether the slave coordinator also has set any fault codes. If fault code 5100 is not set, the fault probably is on the slave coordinator. Check whether the slave coordinator also has set any fault codes.Check that the slave coordinator is correctly connected and that it is the correct type. Make sure the power supply functions.
