NOTE:
Each OUTPUT terminal transistor is activated at 10 ms intervals. Therefore after switch is turned ON,
electrical loads are activated with time delay. But this time delay is so short that it cannot be detected by
human senses.
5. Operation mode

Combination switch reading function has operation modes shown below.
a. Normal status

When BCM is not in sleep status, OUTPUT terminals (1-5) each turn ON-OFF every 10 ms.
b. Sleep status

When BCM is in sleep status, transistors of OUTPUT 1 and 5 stop the output, and BCM enters low cur-
rent consumption mode. OUTPUT (2, 3, and 4) turn ON-OFF every 10 ms, and only input from light
switch system is accepted.
CAN COMMUNICATION CONTROL
CAN communication allows a high rate of information transmission through the two communication lines (CAN
L line, CAN H line) connecting the various control units in the system. Each control unit transmits/receives
data but selectively reads required data only. For details of signals that are transmitted/received by BCM via
CAN communication, refer to LAN-6, "
CAN Communication Unit" .

CAN Communication Inspection Using CONSULT-II (Self-Diagnosis)AKS0058C
1. CHECK SELF-DIAGNOSTIC RESULT
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Connect to CONSULT-II, and select “BCM” on “SELECT SYSTEM” screen.
2. Select “BCM control unit ” on “SELECT WORK ITEM” screen, and select “SELF-DIAG RESULTS”.
3. Check display content in self-diagnostic results.

CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions that exist when the noise occurs. Use the Diag-
nostic Worksheet during the interview to document the facts and conditions when the noise occurs and any
customer's comments; refer to BL-12, "
Diagnostic Worksheet" . This information is necessary to duplicate the
conditions that exist when the noise occurs.

The customer may not be able to provide a detailed description or the location of the noise. Attempt to
obtain all the facts and conditions that exist when the noise occurs (or does not occur).

If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer
is concerned about. This can be accomplished by test driving the vehicle with the customer.

After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.

Squeak —(Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard sur-
faces=higher pitch noise/softer surfaces=lower pitch noises/edge to surface=chirping

Creak—(Like walking on an old wooden floor)
Creak characteristics include firm contact/slow movement/twisting with a rotational movement/pitch
dependent on materials/often brought on by activity.

Rattle—(Like shaking a baby rattle)
Rattle characteristics include the fast repeated contact/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.

Knock —(Like a knock on a door)
Knock characteristics include hollow sounding/sometimes repeating/often brought on by driver action.

Tick—(Like a clock second hand)
Tick characteristics include gentle contacting of light materials/loose components/can be caused by driver
action or road conditions.

Thump—(Heavy, muffled knock noise)
Thump characteristics include softer knock/dead sound often brought on by activity.

Buzz—(Like a bumble bee)
Buzz characteristics include high frequency rattle/firm contact.

Often the degree of acceptable noise level will vary depending upon the person. A noise that you may
judge as acceptable may be very irritating to the customer.

Weather conditions, especially humidity and temperature, may have a great effect on noise level.

4. Remove instrument driver lower panel. Refer to IP-11, "Removal and Installation" .
5. After the bolt of the case with the air cleaner is disconnected, and it is moved, the cable is pulled.
6. Remove the grommet on the dashboard, and pull the hood lock cable toward the passenger room.
CAUTION:
While pulling, be careful not to damage (peeling) the outside of the hood lock cable.
INSTALLATION
1. Pull the hood lock cable through the panel hole to the engine room.
Be careful not to bend the cable too much, keeping the radius
100mm (3.94 in) or more.
2. Make sure the cable is not offset from the positioning grommet,
and push the grommet into the panel hole securely.
3. Apply the sealant to the grommet (at * mark) properly.
4. Install the cable securely to the lock.
5. After installing, check the hood lock adjustment and hood
opener operation.
Hood Lock Control InspectionAIS0051H
CAUTION:
If the hood lock cable is bent or deformed, replace it.
1. Make sure that the hood lock secondary latch is properly
engaged with the secondary striker with hood's own weight.
2. Make sure that the hood lock primary latch is securely engaged
with the hood striker with hood's own weight by dropping it from
approx. 200 mm (7.87 in) height.
CAUTION:
Do not drop hood from a height of 300 mm (11.81in) or
more.
3. When pulling hood opener lever gently, make sure that front end of the hood rises by approximately 20
mm and that hood striker and hood lock primary latch are disengaged. Also make sure that hood opener
returns to the original position.

Key Reminder Door System
When door lock and unlock switch is operated to lock doors with ignition key put in key cylinder and any door
open, all door lock actuators are locked and then unlocked.
Key reminder door mode can be changed using “WORK SUPPORT” mode in “ANTI-LOCK OUT SET”.

CAN Communication System DescriptionAIS004LQ
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.

Panic Alarm Operation
When key switch is OFF (when ignition key is not inserted in key cylinder), BCM turns on and off horn and
headlamp intermittently with input of PANIC ALARM signal from key fob.
The alarm automatically turns off after 25 seconds or when BCM receives any signal from key fob.
Panic alarm operation mode can be changed using “PANIC ALARM SET” mode in “WORK SUPPORT”.
Refer to BL-67, "
