TC and CG Terminal Circuit: Description

DTC output mode is set by connecting terminals TC and CG of the DLC3.

DTCs are displayed by blinking of the SRS warning light.

HINT: 

• When multiple warning lights in the combination meter blink continuously, a ground short in the wiring or an ECU connected to terminal TC of the DLC3 is suspected.
• A DTC output mode signal is transmitted through the CAN communication system to each ECU including the airbag sensor assembly. Thus when multiple systems do not enter DTC output mode, there may be a power management control ECU malfunction.
