VEHICLE STABILITY CONTROL SYSTEM (for Sedan) - TS and CG Terminal Circuit


DESCRIPTION

In the Test Mode (signal check), a malfunction in the speed sensor that cannot be detected when the vehicle is stopped can be detected while driving.
Transition to the sensor check mode can be performed by connecting terminals TS and CG of the DLC3 and turning the ignition switch from off to ON.
