VEHICLE STABILITY CONTROL SYSTEM 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 engine switch from off to on (IG).
