TC and CG Terminal Circuit

DESCRIPTION

The DLC3 circuit enables reading of Diagnostic Trouble Codes (DTCs) with no intelligent testers by connecting terminals TC and CG of the DLC3 connector.

Stored DTCs are displayed in blinking patterns of the CRUISE MAIN indicator light located on the combination meter.

HINT: When a particular warning light blinks continuously, a ground short in the wiring of terminal TC of the DLC3 or an internal ground short in the relevant ECU is suspected.
