Automotive Lighting Control Module v.3.0 Controls vehicle lighting systems based on various inputs and stored variables. Operation: Headlights: Turn ON parking lights switch and headlights switch at the same time and headlights will come on regardless of light level or ignition switch position. Leave Headlights Switch ON (w/o parking lights switch ON- requires switch modification) for automatic headlights mode. Headlights and parking lights come on with ignition ON and light level below set point. (See Mode 1 to set) They stay ON for a set amount of time after turning OFF ignition. (See Mode 2 to set time) With ignition OFF, press LOCK or UNLOCK and immediately repeat UNLOCK to turn ON headlights and rear lights using Keyless Entry. With ignition OFF, press LOCK or UNLOCK and immediately repeat LOCK to turn OFF exterior lights before the time has expired and they have turned off automatically. Dome Light: Open door or turn ON manual dome switch and Dome Light comes on. Light will stay ON until the safety timer turns it off to save the battery. (see mode 4 to set time) If ignition ON it will stay on indefinately. The following actions will turn on the Dome Light for a short period of time: (See Mode 3 to set time) . Open and then Close the car door. Turn OFF ignition (if this option is active. See mode 7) UNLOCK door (if this option is active. See mode 8) The following actions will turn OFF the Dome Light: Turn manual Dome Switch ON and back OFF. Turn ON ignition. (if this option is active: See Mode 7) Press LOCK on Keyless Entry (if this option is active: See Mode 8) If the light level is not dark enough, the Manual Dome Switch is the only way to turn ON the dome light. See Mode 1 to set this level. Dome Light Lock-Out. Turn Dome Light Switch ON-OFF-ON rapidly, and leave ON. Dome Light will go off and not come on again until Lock Out is cleared by turning off the Manual Dome Switch. Parking Lights: The Parking Lights operate whenever the Manual Parking Light switch is ON. They operate whenever the Automatic Headlights are ON. They flash to indicate reception of signals from the Keyless Entry system. LOCK (1 flash), UNLOCK (2 flashes), and TR (3 flashes). They flash once whenever Setup Switch is pressed. Soft-ON/ Soft-OFF: The dome light control is equipped with a PWM driver that lets the light start dim and build up to full brightness. The rate at which the light builds up can be adjusted. The rate at which it dims down can be adjusted sepatately. See modes 5 and 6. The Power Darlington Switch is designed for intermittent use during the Soft-OFF and Soft-ON transitions. It has no heat sink. Once the lights are at full power, the Dome Bypass Relay closes and carries the load. The Power Darlington Switch turns off to prevent overheating. See connection diagram. Setup/ Operating Modes: Press Setup Switch to advance modes. Lock and Unlock switches adjust the Setup Variables. Advancing from Mode 8 to Mode 0 (normal operation) saves changes to EEPROM. Mode 0- Normal Operation: System operates normally. Variables are not altered. LED in module will turn ON when light level drops below threshold value (only if ignition is ON). Small blips of light about 4 times a second indicate normal operation with ignition off, or with ignition ON and a high light level. Mode 1- Light Level: Press Setup Switch once. Parking Lights will flash once. LED in module will flash code 1. Press Setup Switch again to advance modes without altering existing value. Press LOCK switch to save the current ambient light level as the Threshold Level below which the automatic functions will activate. When the daylight level reaches the point where you want headlights, enter Mode 1 and press LOCK. Mode 2- Headlights Delay: Press Setup Switch again. Parking lights will flash. LED will flash code 2. Press Setup Switch to advance modes without altering existing value. Otherwise, press LOCK to erase old Delay setting and set it to 10 seconds. Each additional press of LOCK adds another 10 seconds. (10 to 300 sec range) Mode 3- Dome Light Delay: Press Setup Switch again. Parking lights will flash. LED will flash code 3. Press Setup Switch to advance modes without altering existing value. Otherwise, press LOCK to erase old Delay setting and set it to 10 seconds. Each additional press of LOCK adds another 10 seconds. (10 to 300 sec range) Mode 4- Dome Light Safety Timer: Press Setup Switch again. Parking lights will flash. LED will flash code 4. Press Setup Switch to advance modes without altering existing value . Otherwise, press LOCK to erase old Delay setting and set it to 1 minute. Each additional press of LOCK adds another minute. (1 to 15 min range) Mode 5- Soft-ON Delta Rate: Press Setup Switch again. Parking lights will flash. LED will flash code 5. Press Setup Switch to advance modes without altering existing setting. Otherwise, press LOCK to increase the speed at which the Dome Light turns ON. Press UNLOCK to decrease this speed. There are 10 steps to this setting. Each press changes the value one step. You can operate the manual Dome Switch to view the new setting before changing modes. Mode 6- Soft-OFF Delta Rate: Press Setup Switch again. Parking lights will flash. LED will flash code 6. Press Setup Switch to advance modes without altering existing setting. Otherwise, press LOCK to increase the speed at which the Dome Light turns OFF. Press UNLOCK to decrease this speed. There are 10 steps to this setting. Each press changes the value one step. You can operate the manual Dome Switch to view the new setting before changing modes. Mode 7- Ignition Controlled Dome Light: Press Setup Switch again. Parking lights will flash. LED will flash code 7. Press Setup Switch to advance modes without altering existing setting. Otherwise, press LOCK to turn ON this setting; or UNLOCK to turn it off. With this setitng ON, the dome light will turn ON when ignition is turned OFF. And OFF when the ignition is turned ON. Mode 8- Lock Controlled Dome Light: Press Setup Switch again. Parking lights will flash. LED will flash code 8. Press Setup Switch to advance modes without altering existing setting. Otherwise, press LOCK to turn ON this setting; or UNLOCK to turn it off. With this setting ON, the dome light will turn ON when doors are UNLOCKED and OFF when they are LOCKED. Press Setup Switch again to SAVE the CHANGES and return to Normal Operation. If you don’t advance to Mode 0 after changing settings, the controller will revert to the old settings next time battery power is lost.
