Toyota Venza: TC and CG Terminal Circuit
DESCRIPTION
Connecting terminals TC and CG of the DLC3 causes the ECU to display the DTC by blinking the ABS warning and slip indicator lights.
WIRING DIAGRAM
CAUTION / NOTICE / HINT
HINT:
When the warning lights continue to blink, a ground short in the wiring of terminal TC of the DLC3 or an internal ground short in one or more ECUs is suspected.
