POWER CONSUMPTION CONTROL SYSTEM : System DescriptionINFOID:0000000006274795
OUTLINE
BCM incorporates a power saving control function t hat reduces the power consumption according to the
vehicle status.
BCM switches the status (control m ode) by itself with the power saving control function. It performs the sleep
request to each unit (IPDM E/R, combination meter, dr iver seat control unit, automatic back door control
module, pre-crash seat belt control unit and CAN gat eway) that operates with the ignition switch OFF.
Normal mode (wake-up)- CAN communication is normally performed with other units
- Each control with BCM is operating properly
CAN communication sleep mode (CAN sleep)- CAN transmission is stopped
- Control with BCM only is operating
Stop lamp switch signal Stop lamp switch TCM (CAN) Inputs the stop lamp switch 1
signal and stop lamp switch 2
signal, and transmits it via CAN
communication.
Low tire pressure warning lamp
signal Low tire pressu
re warning con-
trol unit Combination meter (CAN)Transmits the received low tire
pressure warning signal via
CAN communication.
Buzzer request signal Low tire pressu
re warning con-
trol unit Combination meter (CAN)Transmits the received buzzer
request signal via CAN commu-
nication.
Horn request signal Low tire pressu
re warning con-
trol unit IPDM E/R (CAN)Received the horn request sig-
nal, transmits the horn reminder
signal via CAN communication.

AUTO ACTIVE TEST
Description
In auto active test, the IPDM E/R sends a drive signal to the following systems to check their operation.
Oil pressure warning lamp
Rear window defogger
Front wiper (LO, HI)
Parking lamp
License plate lamp
Tail lamp
Side marker lamp
Front fog lamp
Headlamp (LO, HI)
A/C compressor (magnet clutch)
Operation Procedure
CAUTION:
Never perform auto active test in the following conditions.
Engine is running.
CONSULT-III is connected.
1. Close the hood and lift the wiper arms from the windshield. (Prevent windshield damage due to wiper
operation)
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2. Turn the ignition switch OFF.
3. Turn the ignition switch ON, and within 20 seconds, pr ess the driver door switch 10 times. Then turn the
ignition switch OFF.
CAUTION:
Close passenger door.
4. Turn the ignition switch ON within 10 seconds. Af ter that the horn sounds once and the auto active test
starts.
CAUTION:
Engine starts when igniti on switch is turned ON while brake pedal is depressed.
5. The oil pressure warning lamp starts blinking when the auto active test starts.
6. After a series of the following operations is repeated 3 times, auto active test is completed.
NOTE:
When auto active test has to be cancelled halfway through test, turn the ignition switch OFF.
When auto active test is not activated, door swit ch may be the cause. Check door switch. Refer to DLK-117,
"ComponentFunctionCheck".
Inspection in Auto Active Test
When auto active test is actuated, the following operation sequence is repeated 3 times.
Operation
sequence Inspection location Operation
1 Oil pressure warning lamp Blinks continuously during operation of auto active test
