DESCRIPTION

Terminals TC and CG are located in the DLC3.
The DLC3 is located under the instrument panel under cover. When terminals TC and CG are connected, DTCs in normal mode or test mode can be read from the Malfunction Indicator Lamp (MIL) in the combination meter assembly.
Also, terminal SIL is located in the DLC3. This terminal is used for M-OBD communication with the intelligent tester.
