56. with the cable that it was previously connected to If the sensor or module still does not communicate then it would indicate a problem with the sensor or module itself 3 5 5 Ohm Test 26 The following test will check for any short circuits in the cabling Disconnect all the height sensors modules and roll sensors from the CANbus The Display Bus can be left connected Note If you are also removing the sensors from their mounting brackets ensure you write down the serial number and location of each sensor so it can be installed back in its previous location For most systems disconnecting the Valve Module will also create a break in the CANbus system You can replace the module with a two way coupler to ensure the CANbus remains continuous from front to back There are two termination couplers located at the end of each wing tip that can be removed and used in place of the Valve Module Locate the network cable COI that plugs into the Control Module Disconnect the cable from the Control Module Figure 4 The Ohm test will be performed on this connector Figure 5 Connector Pin Out 5 Test the resistance of every pin combination with an ohm meter on the Norac CANbus Test Point TPI Figure 10 You may need to remove the wedge lock on the connector to get a good connection from the meter probe to the pin The following table lists the values for each pin combination The Norac bus must not have power connected to it
