System DiagramINFOID:0000000003894301
System DescriptionINFOID:0000000003894302
OUTLINE
 Exterior lamp battery saver system is controlled by each function of BCM and IPDM E/R.
Control by BCM- Combination switch reading function
- Headlamp control function
- Exterior lamp battery saver function
Control by IPDM E/R- Relay control function
 BCM turns the exterior lamp* OFF after a period of time to prevent the battery from over-discharge when the
ignition switch is turned OFF with the exterior lamp ON.
*: Headlamp (LO/HI), parking lamp, tail lamp, license plate lamp, front fog lamp and rear fog lamp.
EXTERIOR LAMP BATTERY SAVER ACTIVATION
BCM activates the timer and turns the exterior lamp OFF 5 minutes after the ignition switch is turned from ON
→ OFF with the exterior lamps ON.
NOTE:
 Headlamp control function turns the exterior lamps ON normally when the ignition switch is turned ACC or
the engine started (both before and after the exterior lamp battery saver is turned OFF).
 The timer starts at the time that the lighting switch is turned from OFF → 1ST or 2ND with the exterior lamp
OFF.

Part Description
BCM Detects each switch condition by the combination switch reading function.
 Activates the battery saver to turn the exterior lamps OFF according to the vehicle
condition.
- Requests each relay OFF to IPDM E/R (with CAN communication).
IPDM E/RControls the integrated relay according to the request from BCM (with CAN communi-
cation).

 Vehicle Condition (BCM detected condition)
IGN Counter
IGN counter indicates the number of times that ignition switch is turned ON after DTC is detected.
 The number is 0 when a malfunction is detected now.
 The number increases like 1 → 2 → 3...38 → 39 after returning to the normal condition whenever ignition
switch OFF → ON.
 The number is fixed to 39 until the self-diagnosis results are erased if it is over 39.

Diagnosis DescriptionINFOID:0000000003894312
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
