CHECK DLC3
СИСТЕМА ECD - TC and CG Terminal Circuit
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.

INSPECT COMBINATION METER ASSEMBLY (MIL CIRCUIT)
СИСТЕМА ECD - MIL Circuit
DESCRIPTION
The MIL is used to inform the user when the ECM has detected a vehicle malfunction.
By turning the ignition switch to ON, power is supplied to the MIL circuit and the ECM provides the circuit ground that illuminates the MIL.
Operation of the MIL should be checked visually: When the ignition switch is first turned to ON, the MIL should illuminate. When the engine is started, the MIL should turn off.
