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.
