SYSTEM EXL-161 < SYSTEM DESCRIPTION > [HALOGEN HEADLAMP] C D E F G H I J K M A B EXL N O P • BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn sig- nal lamp operating. NOTE: The blinking speed is normal while operating the hazard warning lamp. PARKING, LICENSE PLATE, SIDE MARKER AND TAIL LAMP SYSTEM INFOID:0000000010121429 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 - Lighting switch AUTO, with the front fog lamp switch ON and the power switch ON • 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. PARKING, LICENSE PLATE, SIDE MARKER AND TAIL LAMP SYSTEM : Fail-Safe INFOID:0000000010121431 CAN COMMUNICATION CONTROL When CAN communication with BCM is impossible, IPDM E/R performs fail-safe control. After CAN communi- cation recovers normally, it also returns to normal control. If No CAN Communication Is Available With BCM FRONT FOG LAMP SYSTEM JMLIA1818GB Control part Fail-safe operation • Parking lamp • Turns ON the tail lamp relay when the power switch is turned ON |
