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 the
conditions below are present. Then it transmits a sleep-ready signal (ready) to BCM via CAN communica-
tion.
- Front wiper fail-safe operation
- Outputting signals to actuators
- Switches or relays operating
- Auto active test is starting
- Emergency OFF
- 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 mode, the IPDM E/R sends a drive signal to the following systems to check their operation.
Oil pressure low/coolant pressure high warning indicator
Oil pressure gauge
Rear window defogger
Front wipers
Tail, license and parking lamps
Front fog lamps
Headlamps (Hi, Lo)
A/C compressor (magnetic clutch)
Cooling fan
Operation Procedure
1. Close the hood and front door RH, and lift the wiper arms from the windshield (to prevent windshield dam-
age due to wiper operation).
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield before hand.
2. Turn ignition switch OFF.
3. Turn the ignition switch ON and, within 20 seconds, press the front door switch LH 10 times. Then turn the
ignition switch OFF.
4. Turn the ignition switch ON within 10 seconds. After 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 mode has to be cancelled halfway through test, turn ignition switch OFF.
CAUTION:
• If auto active test mode cannot be actuated, check door switch system. Refer to DLK-65, "
DRIVER
SIDE : Description" (with Intelligent Key system), DLK-499, "DRIVER SIDE : Description" (without
Intelligent Key system).
Do not start the engine.
