REAR FOG LAMP SYSTEM
System DiagramINFOID:0000000003894297
System DescriptionINFOID:0000000003894298
OUTLINE
Rear fog lamp is controlled with the combination switch reading function and the rear fog lamp control function
of BCM.
REAR FOG LAMP OPERATION
 BCM detects the condition of the combination switch by the combination switch reading function.
 BCM supplies voltage to rear fog lamp according to the rear fog lamp ON condition.
Rear fog lamp ON condition- Rear fog lamp switch signal is input with front fog lamp ON and rear fog lamp OFF
Rear fog lamp switch ON with any of following condition.- Lighting switch 2ND
- Lighting switch 1ST, and front fog lamp switch ON
 BCM transmits the rear fog lamp status signal to the combination meter with CAN communication.
 Combination meter turns the rear fog lamp indicator lamp ON according to the rear fog lamp status signal.

 Vehicle Condition (BCM detected condition)
IGN Counter
IGN counter indicates the number of times that ignition switch is turned ON after DTC is detected.
 The number is 0 when a malfunction is detected now.
 The number increases like 1 → 2 → 3...38 → 39 after returning to the normal condition whenever ignition
switch OFF → ON.
 The number is fixed to 39 until the self-diagnosis results are erased if it is over 39.
