Diagnostic Codes
The ViewPort displays diagnostic codes for the compressor system and the engine. Listings
of these codes are provided in this section.
The engine diagnostic codes can also be read with the engine manufacturer's service tool. A
service tool connector is provided in the electrical harness, providing access to the J1939 CAN
network. For advanced engine troubleshooting, it is recommended that the manufacturer's
service tools and service literature be used.
