There are two tests on the next screen, run them both.At the tool options screen select F9, CANdi Diagnostics.You’ll get 12V from the DLC (now it takes me a half hour to find the “DLC means” Data Link Connector “and is what we also call the OBD2 connector, so be prepared to be stumped by TLA’s (Three Letter Acronyms).With the car ignition off, connect the GM Tech2 and CANdi module (which is now one long cable).Suspect the pins arent making the best contact. I need to do this every now and then with my clone one. Plug it back in and make sure its real snug, then plug it into the obd port. Then, disconnect the connector leaving the candi adapter going to the OBD port. “CANdi module was not detected for Tech2”įirst, please make sure you plugged the candi adapter in to the car and the tech 2 before powering up How-to’s of CANDI module communication errors: How will you do with “NO CANDI Communication Established”? In the vent of a problem,the LED will be constantly illuminated. When functioning properly, CANdi’s LED flashes. The vehicle side connection remains unchanged using the existing adapter to interface between the Burndy connector and the SAE J1962 connector. – provides high speed UART communications with Tech 2ĬANdi adapter connects the Tech II by way of the existing Data Link Connector (DLC) Burndy Connector. – support simultaneous communications on three CAN buses
The primary function of the CANdi module is to add CAN capability to the Tech 2 scan tool. Still use a OBDII connector but the Candi module is needed to read the data on the CAN Network. Corvettes 2005 and newer use the CAN Network. The CANDI module reads the CAN Network on cars that have it. W hat is the real purpose of the candi module?
This allows the existing Tech 2 software to be used with no changes, whether or not the CANdi module is installed.
That is, unless the Tech 2 enables features specific to the CANdi module. The module powers up in a way that makes it transparent to the user. Installed, the CANdi module is fully backward compatible with current tester functionality. The Controller Area Network Diagnostic Interface (CANdi) is an in-cable module that works with the existing Tech 2 components including the VCI, cables and adapters. The CANdi module connects between the Tech 2’s diagnostic link cable and the OBD adapter. In order to perform diagnostics on a vehicle that uses the CAN interface, you will need the Tech 2 and a CAN diagnostic interface module. What is the real purpose of the candi module?Īn industry change in protocol from OBD II to Controller Area Network (CAN) is ongoing.
