DESCRIPTION
The DLC3 circuit enables reading of Diagnostic Trouble Codes (DTCs) with no Techstream 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.
WIRING DIAGRAM
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.
