POWER CONSUMPTION CONTROL SY STEM : System Description
INFOID:0000000012433270
SYSTEM DIAGRAM
DESCRIPTION
Outline
• IPDM E/R incorporates a power consumption control function that reduces the power consumption accord-
ing to the vehicle status.
• IPDM E/R changes its status (control mode) with the sleep wake up signal received from BCM via CAN com- munication.
Normal mode (wake-up)- CAN communication is normally performed with other control units.
- Individual unit control by IPDM E/R is normally performed.
Low power consumption mode (sleep)- Low power consumption control is active.
- CAN transmission is stopped.
Sleep Mode Activation
• IPDM E/R judges that the sleep-ready conditions are fulfilled when the ignition switch is OFF and none of theconditions below are present. Then it transmits a sleep-ready signal (ready) to BCM via CAN communica-
tion:
- Outputting signals to actuators
- Switches or relays operating
- Output requests are being received from control units via CAN communication.
• IPDM E/R stops CAN communication and enters the low power consumption mode when it receives a sleep
wake up signal (sleep) from BCM and the sleep-ready conditions are fulfilled.
Wake-up Operation
• IPDM E/R changes from the low power consumption mode to the normal mode when it receives a sleep
wake-up signal (wake up) from BCM or any of the following conditions is fulfilled. In addition, it transmits a
sleep-ready signal (not-ready) to BCM via CAN communication to report the CAN communication start:
- Ignition switch ON
- An output request is received from a control unit 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:
• Front wiper (LO, HI)
• Parking lamp
• Side marker lamp
• License plate lamp
• Tail lamp
• Front fog lamp
• Headlamp (LO, HI)
• A/C compressor (magnet clutch)
• Cooling fan
Operation Procedure
NOTE:
Never perform auto active test in the following conditions:
• Passenger door is open
• CONSULT 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.
4. Turn the ignition switch ON within 10 seconds. Af ter that the horn sounds once and the auto active test
starts.
5. 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 halfw ay 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-98,
"ComponentFunctionCheck" (with Intelligent Key system) or DLK-232, "ComponentFunctionCheck"
(without Intelligent Key system).
Inspection in Auto Active Test
When auto active test is actuated, the following operation sequence is repeated 3 times.
Operation se-
quence Inspection location
Operation
1 Front wiper LO for 5 seconds → HI for 5 seconds
2 •Parking lamp
• Side marker lamp
• License plate lamp
• Tail lamp
• Front fog lamp (if equipped) 10 seconds
3 Headlamp LO for 10 seconds →HI ON ⇔ OFF 5 times
4 A/C compressor (magnet clutch) ON ⇔ OFF 5 times
5 Cooling fan LO for 5 seconds → MID for 3 seconds → HI for 2 seconds

DIAGNOSIS SYSTEM (IPDM E/R)
Concept of Auto Active Test
• IPDM E/R starts the auto active test with the door
switch signals transmitted by BCM via CAN communica-
tion. Therefore, the CAN communication line between IPDM E/R and BCM is considered normal if the auto
active test starts successfully.
• The auto active test facilitates troubleshooting if any systems controlled by IPDM E/R cannot be operated.
