ALTERNATOR CONTROL
IPDM E/R outputs power generation command signal (PWM signal) to the alternator according to the status of
the power generation command value signal received from ECM via CAN communication. Refer to CHG-7,
"System Diagram".

 IPDM E/R reads the status of the oil pressure switch and transmits the oil pressure switch signal to BCM via
CAN communication. Refer to MWI-22, "
WARNING LAMPS/INDICATOR LAMPS : System Diagram".
 IPDM E/R reads the status of the hood switch and transmits the hood switch signal to BCM via CAN commu-
nication. Refer to SEC-17, "
System Diagram".
 IPDM E/R receives the rear window defogger control signal from BCM via CAN communication and trans-
mits it to ECM and AV control unit
* via CAN communication. Refer to DEF-4, "WITH AV CONTROL UNIT :
System Diagram" or DEF-6, "WITHOUT AV CONTROL UNIT : System Diagram".

Diagnosis DescriptionINFOID:0000000003773267
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 warning lamp
 Front wiper (LO, HI)
 Parking lamps
 License plate lamps
 Tail lamps
 Front fog lamps
 Headlamps (LO, HI)
 A/C compressor (magnet clutch)
 Cooling fan
Operation Procedure
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 ignition switch OFF.
3. Turn the ignition switch ON, and within 20 seconds, press 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. After that the horn sounds once and the auto active test
starts.
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 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-57,
"ComponentFunctionCheck".
 Do not start the engine.
Inspection in Auto Active Test Mode
When auto active test mode is actuated, the following 5 steps are repeated 3 times.
Operation
sequenceInspection location Operation
A Oil pressure warning lamp Blinks continuously during operation of auto active test
