BCM (BODY CONTROL MODULE)PFP:284B2
System DescriptionBKS002EV
BCM (Body Control Module) controls the operation of various electrical units installed on the vehicle.
BCM FUNCTION
BCM has combination switch reading function for reading the operation of combination switches (light, wiper
washer, turn signal) in addition to a function for controlling the operation of various electrical components. Also
it has an interface function allowing it to receive signals from the unified meter and A/C amp., and send signals
to ECM using CAN communication.
COMBINATION SWITCH READING FUNCTION
Description
BCM reads combination switch (lighting switch, wiper switch) status, and controls various electrical com-
ponent, according to the results.
BCM reads information of a maximum of 20 switches by combining 5 output terminals (OUTPUT 1-5) and
5 input terminals (INPUT 1-5).
Operation Description
BCM activates transistors of output terminals (OUTPUT 1-5) periodically and, allows current to flow in
turn.
If any (1 or more) switches are turned ON, circuit of output terminals (OUTPUT 1-5) and input terminals
(INPUT 1-5) becomes active.
At this time, transistors of output terminals (OUTPUT 1-5) are activated to allow current to flow. When volt-
age of input terminals (INPUT 1-5) corresponding to that switch changes, interface in BCM detects volt-
age change, and BCM determines that switch is ON.

Sample Operation
When lighting switch 1ST position is turned ON, contact in combination switch turns ON. At this time if
OUTPUT 4 transistor is activated, BCM detects that voltage changes in INPUT 5.
When OUTPUT 4 transistor is ON, BCM detects that voltage changes in INPUT 5, and judges that lighting
switch 1ST position is ON. Then BCM sends tail lamp and clearance lamp request signal to IPDM E/R
using CAN communication.
When OUTPUT 4 transistor is activated again, BCM detects that voltage changes in INPUT 5, and recog-
nizes that lighting switch 1ST position is continuously ON.
NOTE:
Each OUTPUT terminal transistor is activated at 10 ms intervals. Therefore after switch is turned ON, electri-
cal loads are activated with time delay. But this time delay is so short that it cannot be detected by human
senses.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
TRUNK
Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1. Trunk lid dumpers out of adjustment
2. Trunk lid striker out of adjustment
3. Trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sunvisor shaft shaking in the holder
3. Front or rear windshield touching headlining and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
SEATS
When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. Rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

Room Lamp and Ignition Key ring Illumination Operation
When the following conditions come:
condition of interior lamp switch is DOOR position;
door switch OFF (when all the doors are closed);
Remote keyless entry system turns on interior lamp (for 30 seconds) with input of UNLOCK signal from key
fob. For detailed description, refer to LT- 2 1 9 , "

CAN Communication System DescriptionBIS000WG
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.
