DAYTIME LIGHT SYSTEM
Revision: 2004 November 2004 FX35/FX45
DAYTIME LIGHT SYSTEMPFP:284B2
Component Parts and Harness Connector LocationAKS007MZ
System DescriptionAKS007N0
DAYTIME LIGHT SYSTEM turns on Daytime Light Lamps while driving. Day Light Lamps are not turned on if
engine is activated with Parking Brake on. Take off Parking Brake to turn on Daytime Light Lamps. The lamps
turn off when Lighting Switch is in the 2ND position or AUTO position (Head Lamp is “ON”) and when Lighting
Switch is in the PASSING position. (Daytime Light Lamps are not turned off only by Parking Brake itself.)
An parking brake signal and engine run or stop signal are sent to BCM (body control module) by CAN commu-
nication line, and control daytime light system.
