Taillight Disconnection Warning

With the ignition switch on and the light control switch turned to TAIL or HEAD position, if the taillight circuit is open, the light failure sensor detects the failure by the change in current flowing from terminal No. 3 of the light failure sensor to terminal No. 9 and the warning circuit of the light failure sensor is activated. As a result, the current flows from terminal No. 4 of the light failure sensor to terminal No. 11 to GROUND and turns the rear lights warning light on, which remains on until the light control switch is turned off.
