|
Halogen |
Draw more power 12V DC |
|
|
High intensity discharge (HID) |
Draws less power - 3 stages of operation - 12V DC -> control side - bulb side -> AC *High voltage* |
|
|
Sealed beam |
Textured glass surface - directs light beam - lines focus to road - replace whole thing |
|
|
Headlights |
- reflection systems • sealed beam/halogen • composite/halogen • composite/HID - projection systems • projection/halogen • projection/HID |
|
|
Reflector beam |
- clear/no-texture cover - light beam focused by reflector |
|
|
Headlight bulb types |
Halogen many types - dual filament 55W low beam/60W high beam - single filament 55W low beam or driving light - halogen bulb produces light at about 3200k colortemp |
|
|
Dont touch Halogen light with bare fingers! |
Oil in hands over heat bulb |
|
|
Headlight bulb type |
HID - D1S/D1R (for refector systems) •ignition fit onto base of bulb - D2S/D2R •ignitor built into ballast - D3S/D4S •mercury free "R" reflector and "S" projector OEM HID bulbs are rated - 35W - 4100K/5000K colortemp |
|
|
Projector |
- cutoff ->light beam - magnifies light beam |
|
|
Halogen |
- Oils from skin can blister glass envelope - bulb must be seated correctly •light not directed properly •mets housing |
|
|
Ballast |
12V -> high voltage AC Step-up transformer/inverter |
|
|
HID operation |
HID = high voltage 1. Startup 25,000-30,000 ACV 2. Warmup 360 ACV 3. Steady running 55 ACV HID low beam/halogen high beam HID projector LO/HI beam |
|
|
25,000-30,000 volts HID |
Establish arc across bulb eletrodes |
|
|
Warm-up |
360V AC - light intensity/output |
|
|
No light on bulb ballast |
Swap bulbs side to side to verify |
|
|
Flickering on/off |
Bad ballast - running through stages of operation Start up, warm up, running |
|
|
HID |
- Replace both bulbs to ensure color consistency(colorshift) 4100k-5000k - keep glass envelope clean - high system voltage |
|
|
HID diagnosis |
- pink/purple light -> replace - no light - flickering light |
|
|
Clear lens |
- UV coating peeling -> replace - fade/yellowing/clouding • polish/way |
|
|
Initial startup AFS system |
Operates headlight control motor for positioning and diagnostics - level sensor -> scan tool relearn - suspension service/alignment |
|
|
Ignition on |
1. AFS switch is "on" position 2. Check high/low beam function 3. Visual inspection of projector sweep function 4. Scan for codes Tire pressure/ride height |
|
|
Adaptive front lighting/AFS |
Auto level control |
|
|
AFS |
- Steering angle - vehicle speed |
|
|
Auto level/AFS |
- broken glass can jam system - mechanical headlight adjustment - auto level/AFE scan tool relearn |
|
|
Mechanical adjustment |
Headlight assembly RE & RE |
|
|
Auto level/AFS relearn |
- suspension replacement/service - height sensor removal service - AFS ECU replacement |
|
|
Headlight aiming |
- floor must be level - headlamp 7.62m(25ft) from screen or wall - vertical aim should be centered on low beam mark - horizontal should drop 75mm(2.9") to 190mm(3.9") below lamp horizontal centerline |
|
|
Optical aiming |
- aimer takes place of large screen and 7m(25ft) space - compensates for sloped floor |
|
|
Halogen |
Halogen gases allow tungsten to self repair |
|
|
Exterior lamp operation |
- Conventional bulb - LED •long life spam, low hear, low electrical power consumption |
|
|
Input -> PID Parameter Identification |
Scan tool/test LH/RH function |
|
|
Outputs |
Function test with scan tool - command LH or RH "on" to test function |
|
|
"B" |
Body code |
|
|
Turn signal/hazard flasher |
Hybrid flasher - common/IC with mechanical relay - if bulb burns out flash rate increases Solid state flasher - no moving parts/can be part of BCM - if bulb burns out flash rate increases |
|
|
Manual transmission |
Reverse light switch operated by mechanical linkage - shifter - shift fork |
|
|
Door switch -> ground switch |
- 2 wire switch - 1 wire ->switch grounds through body |
|
|
Interior light systems |
Illuminated entry: - Courtesy lights - dome lights - map/reading lights - interior dome/courtesy entry •RKE Fob is: unlocked/locked •smartkey detected |
