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 fu lfilled 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 followi ng 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.
IGNITION BATTERY SAVER LOGIC
If the ignition is ON for 30 minutes with the engine OFF, the IPDM E/R and BCM turn OFF to save the battery.

AUTO ACTIVE TEST
Description
In auto active test mode, the IPDM
E/R sends a drive signal to the follo wing systems to check their operation.
• Front wiper (LO, HI)
• Front fog lamps
• Parking lamps
• Side marker lamps
• Tail lamps
• License plate lamps
• Daytime running lamps
• Headlamps (LO, HI)
• A/C compressor
• Cooling fans (LO, HI)
Operation Procedure
CAUTION:
Do not start the engine.
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield before hand.
NOTE:
• If auto active test mode cannot be actuat ed, check door switch system. Refer to DLK-100,
"Component Function Check".
• When auto active test mode has to be cancelled halfway through test, turn ignition switch OFF.
1. Close the hood and lift the wiper arms from the windshield. (Prevent windshield damage due to wiper
operation)
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. 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.
Inspection in Auto Active Test Mode
When auto active test mode is actuated, the following operation sequence is repeated 3 times.
*: Outputs duty ratio of 50% for 5 seconds → duty ratio of 100% for 5 seconds on the cooling fan control module.
Operation se-
quence Inspection Location Operation
1 Front wiper LO for 3 seconds → HI for 3 seconds
2 •Front fog lamps
• Parking lamps
• Side marker lamps

• License plate lamps 10 seconds
3 Daytime running lamps 10 seconds
4 Headlamps LO ⇔ HI 5 times
5 A/C compressor ON ⇔ OFF 5 times
