System Description
INFOID:0000000001604598
OUTLINE
• Front fog lamp is integrated into the front combination lamp.
• Front fog lamp is controlled by combination switch reading function and front fog lamp control function of
BCM, and relay control function of IPDM E/R.
NOTE:
For Canada models, the front fog lamp is turned ON as the daytime running light. Refer to
for the detail.
FRONT FOG LAMP OPERATION
• BCM detects the combination switch condition by the combination switch reading function.
• BCM transmits the front fog lamp request signal to IPDM E/R with CAN communication according to the
front fog lamp ON condition.
Front fog lamp ON condition
- Front fog lamp switch ON with the headlamp ON (except for the high beam ON)
• IPDM E/R turns the integrated front fog lamp relay ON, and turns the front fog lamp ON according to the
front fog lamp request signal.
