EXTERIOR LAMP BATTERY SAVER SYSTEM (WITH DTRL) : System Description

INFOID:0000000006452115

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 lamps* OFF after a period of time to prevent the battery from over-discharge when

the ignition switch is turned OFF with the exterior lamps ON.

*: Headlamp (LO/HI), parking lamp, tail lamp, license plate lamp, front fog lamp and rear fog lamp

EXTERIOR LAMP BATTERY SAVER ACTIVATION

BCM turns the exterior lamps OFF (battery saver is activated) when all of following condition.
• Exterior lamps ON
• When any of the following conditions is satisfied.
- Driver side door switch is turned from OFF to ON while ignition switch is OFF.
- Ignition switch is turned from ON to OFF while driver side door switch is ON.
NOTE:
When following condition (after the exterior lamp battery saver is activated), exterior lamps can be turned ON.

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 (only for K9K engine models)
• Rear window defogger
• Front wiper motor
• Parking lamp
• License plate lamp
• Tail lamp
• Front fog lamp
• Headlamp (LO, HI)
• A/C compressor (magnet clutch)
• Cooling fan

Operation Procedure

CAUTION:

Wiper arm interferes with food when wiper is operated while wiper arm is in the raised position.
Always perform auto active test without setting wiper arm in the raised position. Always pour water on
front windshield glass in advance to auto active test so that damage on front windshield glass surface
is prevented.
1.

Turn the ignition switch OFF.

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.

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

CAUTION:

Engine starts when ignition switch is turned ON while brake pedal is depressed.

Oil pressure warning lamp starts blinking when the auto active test starts*. (only for K9K engine models)
*: Except for K9K engine models, oil pressure warning lamp turn ON when auto active test start.

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

DLK-87,

"Component Function Check"

(with super lock) or

DLK-258, "Component Function Check"

(without super

lock).

Inspection in Auto Active Test Mode

When auto active test mode is actuated, the following operation sequence is repeated 3 times.

Concept of auto active test

*: Only for models with MR16DDT engine
• 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.
