Diagnostic Information and Procedures
Self-Diagnosis Function for Headlight Auto Leveling SystemS6RW0D9204014
The headlight leveling control module has self-diagnosis function to monitor the system components and circuits while
the headlight auto leveling system is at work. When the headlight leveling control module detects an abnormality in the
system, the headlight leveling warning light in the combination meter turns ON. However, the headlight leveling control
module does not have a function to indicate location of such abnormality.

Height Sensor Removal and Installation (If
Equipped)
S6RW0D9206027
Removal
CAUTION!
• Do not remove bracket (4) and link (3) from
height sensor (2). Removal will spoil its
original function. If faulty condition is
found, replace it with new one in a set.
• If height sensor was dropped from a height
of 30 cm (0.9 ft) or more, replace it with
new one.

1) Disconnect negative (–) cable at battery.
2) Disconnect height sensor connector (1) from height
sensor (2).
3) Remove front and rear height sensor (2) with its
bracket (4) from suspension frame (6) or rear floor
center cross member (7) and lower arm (5).Installation
For installation, reverse removal procedure noting the
following.
• Check that bracket and link of height sensor are not
deformed.
• Tighten height sensor bolts and nuts to specified
torque.
Tightening torque
Height sensor bolt (a): 5.5 N·m (0.6 kgf-m, 4.0 lb-ft)
Height sensor nut (b): 13 N·m (1.3 kgf-m, 9.5 lb-ft)
• Connect connector securely.
• After installation, initialize headlight auto leveling
system referring to “Initialization of Headlight Auto
Leveling System”.

Height Sensor and Its Circuit Inspection (If
Equipped)
S6RW0D9206028
1) Remove front or rear height sensor from vehicle
referring to “Height Sensor Removal and Installation
(If Equipped)”.
2) Connect connector to height sensor.
3) Vary position of height sensor link (1) and measure
voltage between terminals of headlight leveling
control module (4) as described below.
• For front height sensor
Between “G14-20” and “G14-22” terminals of
headlight leveling control module.
• For rear height sensor
Between “G14-19” and “G14-21” terminals of
headlight leveling control module.
If check result is not as specified, perform
inspections of power supply, ground and signal
circuits of front or rear height sensor which is
described under “Inspection of Headlight Leveling
Control Module and Its Circuit (Headlight Auto
Leveling System)”. If circuits are OK, replace
height sensor.

Full rebound position (3): about 4.5 V
Headlight Leveling Control Module Removal
and Installation (If Equipped)
S6RW0D9206029
Removal
1) Disconnect negative (–) cable at battery.
2) Remove glove box.
3) Disconnect connector (1) from headlight leveling
control module (2).
4) Remove headlight leveling control module with its
bracket from steering support member (3).
Installation
For installation, reverse removal procedure noting the
following.
• Connect connector securely.
• After replacing headlight leveling control module with
new one, initialize headlight auto leveling system
referring to “Initialization of Headlight Auto Leveling
System”.
Initialization of Headlight Auto Leveling SystemS6RW0D9206030
Initialization of the headlight auto leveling system is to
make the headlight leveling control module learn signals
which are fed from the height sensors when the vehicle
is at the standard height. Standard height means the
height of the vehicle with a driver but without load in it.
Initialization of the headlight auto leveling system is
required when any of the following works has been
performed.
• Replacement of headlight leveling control module
• Removal of front and/or rear height sensor link from
lower arm
• Removal of front and/or rear height sensor from
suspension frame
• Replacement of front and/or rear height sensor
