VEHICLE STABILITY CONTROL SYSTEM TS and CG Terminal Circuit

DTC Code DTC Name
TS and CG Terminal Circuit

DESCRIPTION

Connecting terminals TS and CG of the DLC3 causes the ECU to display Test Mode DTCs by blinking the ABS warning, tire pressure warning (w/ tire pressure warning system) 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 ignition switch from off to ON.
