SYSTEM DIAGRAM

OUTLINE

Parking, license plate, side marker and tail lamps are controlled by combination switch reading function and
headlamp control function of BCM, and relay control function of IPDM E/R.

PARKING, LICENSE PLATE, SIDE MARKER AND TAIL LAMPS OPERATION

• BCM detects the combination switch condition by the combination switch reading function.
• BCM transmits the position light request signal to IPDM E/R and the combination meter via CAN communi-

cation according to the ON/OFF condition of the parking, license plate, side marker and tail lamps.

Parking, license plate, side marker and tail lamps ON condition

- Lighting switch 1ST
- Lighting switch 2ND
- Lighting switch AUTO, and the auto light function ON judgment.
• IPDM E/R turns the integrated tail lamp relay ON and turns the parking, license plate, side marker and tail

lamps ON according to the position light request signal.

• Combination meter turns the tail lamp indicator lamp ON according to the position light request signal.

SYSTEM DIAGRAM

OUTLINE

Front fog lamp is controlled by combination switch reading function, front fog lamp control function of BCM,
and relay control function of IPDM E/R.

FRONT FOG LAMP OPERATION

• BCM detects the combination switch condition by the combination switch reading function.
• BCM transmits the front fog light request signal to IPDM E/R via CAN communication according to the front

fog lamp ON condition.

Front fog lamp ON condition

- Front fog lamp switch ON, and any of the following condition is satisfied. (except for the high beam ON)
• Lighting switch 2ND
• Lighting switch AUTO (auto light function ON judgment)
IPDM E/R turns the integrated front fog lamp relay ON, and turns the front fog lamp ON according to the front
fog light request signal.
