E1302 OFF CHECK IS ABNORMAL

  • AD
  • Have a look at the attached error code information.
    From a hardware perspective, this is attributable to the mechanical contactors inside the MC Unit.
    However, could be a control board within the MC Unit or harnessing issue.


    MC Unit is the main control for power distribution for Fans, Brakes and Servo Amplifiers.

  • Welcome to the forum...……….:beerchug:

    As the above notice from the Troubleshooting Manual, this error relates to the internal MC Unit.

    You will have to check the harness and possibly replace the MC unit to rectify it.


    Do any other errors appear when you try to reset it?

    If so, can you post the error log?
