BCM (BODY CONTROL MODULE)

BCM - Operation Table of Combination Switches
BCM reads operation status of combination switch using combinations shown in table below.
NOTE:
Headlamp system has a dual switch.
Front Wiper Intermittent Operation
Front wiper intermittent operation is determined from a combination of 3 switches (INT VOLUME 1, 2, and 3)
and vehicle speed signal.
Wiper Intermittent Dial Position Setting
Example: For wiper intermittent dial position 1
Using combination switch reading function, BCM detects ON/OFF status of INT VOLUME 1, 2, and 3.
When combination switch status is as listed below, BCM determines that it is wiper Intermittent dial position 1.

INT VOLUME 1: ON (Continuity exists between combination switch output 3 and input 1.)

INT VOLUME 2: ON (Continuity exists between combination switch output 5 and input 1.)

INT VOLUME 3: ON (Continuity exists between combination switch output 4 and input 2.)

HOODPFP:F5100
Fitting AdjustmentBIS000VP
LONGITUDINAL AND LATERAL CLEARANCE ADJUSTMENT
1. Remove hood lock, loosen the hood hinge nuts and close the hood.
2. Adjust the lateral and longitudinal clearance, and open the hood to tighten the mounting bolts to the spec-
ified torque.
3. Install the hood lock temporarily, and align the hood striker and lock so that the centers of striker and lock
become vertical viewed from the front, by moving the hood lock laterally.
4. Tighten hood lock mounting bolts to the specified torque.
FRONT END HEIGHT ADJUSTMENT
1. Remove the hood lock and adjust the height by rotating the bumper rubber until the hood becomes 1 to1.5
mm (0.04 to 0.059 in) lower than the fender.
2. Temporarily tighten the hood lock, and position it by engaging it with the hood striker. Check the lock and
striker for looseness, and tighten the hood lock mounting bolts to the specified torque.
CAUTION:
Adjust right/left clearance between hood and each part to the following specification.
1. Hood hinge 2. Nut 3. Hood stay
4. Hood lock 5. Bolt
PIIB1752E
Hood (B) - Headlamp (B) : Less than 1.5 mm (0.059 in)
Hood (C) - fender (C) : Less than 1.0 mm (0.039 in)

BL-14
HOOD

SURFACE HEIGHT ADJUSTMENT
1. Remove hood lock, and adjust the surface height difference of hood, fender and headlamp according to
the fitting standard dimension, by rotating RH and LH bumper rubbers.
2. Install hood lock temporarily, and move hood lock laterally until the centers of striker and lock become ver-
tical when viewed from the front.
3. Check that the hood lock secondary latch is properly engaged
with the secondary striker with hood's own weight.
4. Check that the hood lock primary latch is securely engaged with
the hood striker with hood's own weight by dropping hood from
approx. 200 mm (7.87) height.
CAUTION:
Do not drop hood from a height of 300 mm (11.81 in) or
more.
5. Move hood lockup and down until striker smoothly engages the
lock when the hood is closed.
6. When pulling the hood opener lever gently, make sure that front
end of the hood rises by approximately 20 mm (0.79) and that hood striker and hood lock primary latch is
disengaged. Also make sure that hood opener returns to the original position.
7. After adjustment, tighten lock bolts to the specified torque.

Check Headlamp FunctionBIS000XO
First perform the “SELF-DIAG RESULTS” in “BCM” with CONSULT-II, then perform the trouble diagnosis of
malfunction system indicated “SELF-DIAG RESULTS” of “BCM”. Refer to BCS-14, "
CAN Communication
Inspection Using CONSULT-II (Self-Diagnosis)" .
1. CHECK HEADLAMP OPERATION
Does headlamp come on when turning lighting switch “ON”?
YES or NO
YES >> Headlamp operation circuit is OK.
NO >> Check headlamp system. Refer to LT- 6 , "
HEADLAMP - XENON TYPE -" .
Removal and Installation of Intelligent Key UnitBIS001TH
REMOVAL
1. Remove the instrument driver lower panel. Refer to IP-10, "Component Parts Location" .
2. Disconnect Intelligent Key unit connector, remove screw and
Intelligent Key unit.
INSTALLATION
Install in the reverse order of removal.
Intelligent Key Battery ReplacementBIS001TI
DISASSEMBLY AND ASSEMBLY OF INTELLIGENT KEY
1. Release the lock knob at the back of the Intelligent Key and remove the mechanical key.
2. Insert a flat-blade screwdriver (A) wrapped with a close into the
slit of the corner and twist it to separate the upper part from the
lower part.
CAUTION:

Be careful not to touch the circuit board or battery termi-
nal.

The key fob is water-resistant. However, if it does get wet,
immediately wipe it dry.
3. Replace the battery with new one.
4. Align the tips of the upper and lower parts, and then push them
together until it is securely closed.
CAUTION:

When replacing battery, be sure to keep dirt, grease, and
other foreign materials off the electrode contact area.

After replacing the battery, check to make sure all Intelli-
gent Key functions work normally.

TROUBLE DIAGNOSIS FOR SYMPTOMS

2. SYMPTOM CHECK 2
Check symptoms when electrical component (headlamps, etc.) switches are operated.
Do symptoms occur?
YES >> Check if there is a radio, antenna, antenna lead wire, or wiring close to the control unit. If there is,
move it farther away.
NO >> GO TO 3. Check Wheel Sensor and Sensor Rotor. Refer to BRC-30, "
Excessive ABS Function
Operation Frequency" .
