VEHICLE STABILITY CONTROL SYSTEM (for Hatchback with Separate Type Yaw Rate Sensor) - TS and CG Terminal Circuit


DESCRIPTION

In Test Mode (signal check), a malfunction in the 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.
