DTC B2516 [SHIFT POS SIG (P, R)]BKS002FF
1. CHECK SIFT SIGNAL
1. Select “ADAPTIVE LIGHT” on CONSULT-II. Select “DATA
MONITOR” on “SELECT DIAG MODE” screen.
2. When select lever is operated, check indication of the following
item.
OK or NG
OK >> INSPECTION END.
NG >> Check parking/neutral position (PNP) switch. Refer to
AT- 1 6 6 , "
PNP SWITCH" (with A/T) or CVT-62, "DTC
P0705 PARK/NEUTRAL POSITION SWITCH" (with CVT). If above system is normal, replace
AFS control unit. Refer to LT- 9 4 , "
Removal and Installation of AFS Control Unit" .
DTC B2517 [VEHICLE SPEED SIG]BKS002FG
1. CHECK VEHICLE SPEED SIGNAL
1. Select “ADAPTIVE LIGHT” on CONSULT-II. Select “DATA
MONITOR” on “SELECT DIAG MODE” screen.
2. When vehicle is moving, check the value in “VHCL SPD”.
Is the value in speedometer almost same as that in the monitor?
YES >> INSPECTION END.
NO >> Check METER & A/C AMP self-diagnosis result. Refer
to DI-29, "
SELF-DIAGNOSTIC RESULTS" . If above
system is normal, replace AFS control unit.
TEST ITEM Operation condition Reference value

System DescriptionBKS002BA
The height sensor is located on the right side of the rear suspension member. With the lighting switch in the
1ST or 2ND position, the height sensor detects vehicle height change by sensing the displacement of the sus-
pension arm. And the height sensor transmits a corresponding signal to the headlamp aiming motors. The sig-
nal drives the headlamp aiming motors, which adjusts the low beam reflector of each headlamp to an angle
appropriate for the vehicle height.
The aiming motor drive signal level retains when the following conditions are not met.

When the stopped vehicle changes the height and keeps it for more than 10 seconds, the height sensor
outputs a aiming motor drive signal. And height sensor keeps signal voltage to headlamp aiming motor.
Upon reception of the aiming motor drive signal, both headlamp aiming motors cause the low beam reflec-
tors to move to the position commanded by the signal.

When the vehicle is running (excluded when accelerating/decelerating), the height sensor transmits aim-
ing motor drive signal to headlamp aiming motors at the predetermined intervals. The voltage level of
every signal input is maintained unchanged until the next signal is input.
Upon reception of the aiming motor drive signal, both headlamp aiming motors cause the low beam reflec-
tors to move to the position commanded by the signal.

When the vehicle is accelerating or decelerating, the height sensor keeps the same aiming motor drive
signal voltage level rather than changing it, so that the low beam reflectors of both headlamps do not
operate.
When the lighting switch is turned OFF position, the height sensor retains the aiming motor drive signal level
at that moment and stops transmitting the signal.

The height sensor is located on the right side of the rear suspension member and detects vehicle height
change by sensing the displacement of the suspension arm.
When the lighting switch is turned to the 1ST or 2ND position, power is supplied

through IPDM E/R terminal 22

to height sensor terminal 6 and

to front combination lamp RH and LH terminals 3.
At the same time, the vehicle height signal (voltage signal that corresponds to the vehicle height) is applied

through height sensor terminal 7

to front combination lamp RH and LH terminals 6.
Ground is supplied

to front combination lamp RH and LH terminals 4

through grounds E1 and E31.
CAN Communication System DescriptionBKS0041M
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitBKS0041N
