EXTERIOR LAMP BATTERY SAVER SYSTEM : System Description

INFOID:0000000008460280

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, side marker lamp, tail lamp, license plate lamp and front fog lamp.

EXTERIOR LAMP BATTERY SAVER ACTIVATION

BCM activates the timer and turns the exterior lamp OFF 45 seconds 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

ON (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.

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 lamp
• License plate lamp
• Side maker 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.
• CONSULT is connected
• Passenger door is open

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.

Turn the ignition switch OFF.

Turn the ignition switch ON, and within 20 seconds, press the front door switch (driver side) 10 times.
Then turn the ignition switch OFF.

Turn the ignition switch ON within 10 seconds. After that the horn sounds once and the auto active test
starts.

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 halfway through test, turn the ignition switch OFF.
• When auto active test is not activated, door switch may be the cause. Check door switch. Refer to

DLK-55,

"Component Function Check"

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.
