9、 will turn ON if any door is open (4 DOOR AJAR active) (T1). DOME LIGHT will turn OFF if any door is kept opened for 15mins. After all doors are closed AND IGN is OFF, the DOME LIGHT will stay ON for an additional time 8s (T2), THEN a dimming process is started lasting for 2s (T3). After T3 DOME LIG
10、HT is switched OFF. IF IGN is turned ON during these additional time periods (T2、T4 or T5), the DOME LIGHT will turn OFF immediately. IF IGN is ON, whilst any DOOR AJAR input is active, the DOME LIGHT will turn OFF immediately without any delay when all DOOR AJAR inputs are deactivated.RF Dome Light
11、 Control (Dome light Switch=CNTL) :RF Dome Light Control: When all doors are closed AND dome light is ON, RF Lock button press will turn OFF the dome light immediately. IF RF unlock button is pressed, dome light will turn ON for 8s followed by 2s of decay and finally turn OFF. Only car is closed and
12、 locked by RF (It means in the arming mode), then the RF Unlock button will turn on the dome light immediately.2.2 KEY ILLUMINATIONKey Illumination Control: IF FL DOOR AJAR is active (Driver door open) AND IGN is OFF, THEN IGN KEY ILLUM output is activated (Key illumination Lamp turn ON) for the dur

IF IGN goes ON during this time, IGN KEY ILLUM output is deactivated immediately (T2). IF IGN is ON, whilst FL DOOR AJAR is still acti
14、ve, the IGN KEY ILLUM output will turn OFF immediately (No delay). IF Driver door remains open for a period exceeding 3 minutes, Key Illumination Lamp will goes off with decay.2.3 POWER WINDOW CONTROLPower Window Control:The timing chart above is true for LF/RF/LR/RR Window motors.
