AIMING MOTOR DRIVE SIGNAL
(Aiming motor drive signal)

[CIRC 
SHORT TO 
GRND]

When ignition switch is ON, headlamp (LO) ON condi-
tions are satisfied, and the aiming motor drive signal volt-
age that is output to the headlamp aiming motor is 1.25 V 
or less continually for 2 seconds or more.

[CIRC 
SHORT TO 
BATTERY]

When ignition switch is ON, headlamp (LO) ON condi-
tions are satisfied, and the aiming motor drive signal volt-
age that is output to the headlamp aiming motor is 11.25 
V or more continually for 2 seconds or more.

[SIGNAL 
COMPARE 
FAILURE]

When ignition switch is ON, headlamp (LO) ON condi-
tions are satisfied, and the difference between the calcu-
lated value and actual output value for the aiming motor 
drive signal voltage that is output to the headlamp aiming 
motor is 1.75 V or more continually for 2 seconds or more.
