TS and CG Terminal Circuit [08/2013 - ]: Description

WARNING: This page is about a different car, the 2014 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.

Connecting terminals TS and CG of the DLC3 causes the ECU to display Test Mode DTCs by blinking the ABS warning, brake warning / yellow (minor malfunction) and slip indicator lights.

In Test Mode (signal check), a malfunction in a speed sensor that cannot be detected when the vehicle is stopped can be detected while driving.

Sensor check mode can be entered by connecting terminals TS and CG of the DLC3 and turning the power switch from off to on (IG).
