Ch 6 page 8 ELECTRICAL SYSTEM Adding additional VCU software. CANPC will always have the latest software VCU software embedded at the time of release. If new VCU software is released before it is included in the CANPC update version, it can be manually added. Right-click the VCU software you have received and select “copy”. Locate the folder which the “CANPC.exe” file is installed on and paste the new VCU software directly into the same folder. (If this was the folder chosen on step 3 when setting up CANPC). The new VCU software file will now be found automatically by the CANPC program when using the “Download software” function to update the VCU. Figure 8 CIF2 interface 1.
Connect the CIF2 to diagnostic port. The CIF2 unit is made with a integrated OBDII plug and can be plugged directly into the OBDII diagnostic port in the cab. For earlier DA models, use the included OBDII to UMNL mini 12P cable. For MT - series use the UMNL mini 6P connector. 2. Connect the USB cable from the CIF2 into a free USB port on the computer. 3. Turn the ignition to ON. All 3 LED’s on the CIF2 unit should illuminate. This indicates that the CIF2 has power and has a working connection to both CANbus lines (CAN1 and CAN2) on the truck.
