Switch off ignition!
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.
