Code 0C7194 — Safety controller — CAN controller defect in safety computer.

Procedure

1 Check CAN hardware on vehicle side

Procedure

  1. Switch off ignition!

  2. Measure the resistance between CAN1-L and CAN1-H and between CAN2-L and CAN2-H at the transmission controller or the pushbutton selector using a multimeter.

    • A resistance of approx. 60 ohm should be present.

    • If approx. 120 ohms are measured, a CAN terminating resistor is missing.

    • If Infinite is measured, both CAN terminating resistors are missing.

    • If a resistance of approximately or equal to 0 ohm is present, a short-circuit has occurred.

2 Carry out ALADIN diagnosis

Procedure

    Clear event memory

  1. Clear event memory.

    Event memory cleared

    Event memory cleared (Check under ("Reporting > Event Memory > Check mark set")

  2. Possibly test drive

    Should the fault reoccur:

    Upload

  3. Perform an upload with the ALADIN diagnosis software.

  4. Then please contact the VOITH customer service.
