***NEW SECTION*** Glossary Section - submissions needed

YotaTech is finally going to be getting a dedicated Glossary!
This section/thread will contain everything from "SAS" to "IFS" to the various Toyota engines.

In order for this to work we need your help.
I am going to leave this Sticky open for you all to post in.

Only rule for this thread, no BS.
Post up a glossary term, the definition and that is it - no smilies, no banter back and forth, etc...
I will go through and edit it grammatically and for formatting.
If you have an image that is associated with your definition feel free to post it - if you do this, please make the image small, I would say 640x480 at most.

Keep in mind when posting that it is your responsibility to ensure the definition/image you are posting is not Copyright'd or Trademark'd.

Please look and make sure somebody hasn't already posted it.

If you have any questions or you believe that a definition that has already been posted is incorrect, please PM me or another Mod and we will see that it gets corrected.

Remember, this is a glossary not a dictionary.

Thanks for your help,

YotaTech Staff

TECH TERMS

2H - 2-wheel drive / high range
4H - 4-wheel drive / high range
4L - 4-wheel drive / low range
A/T - All-Terrain; often used when referring to tires, a tire that is more apt to off-road conditions however less aggressive than a mud-terrain tire
AAL - Add-a-Leaf
ABS - Anti-lock brake system
ADD - Automatic Disconnecting Differential System; disconnects the front axles and hub assemblies from the drive shaft at the differential when the vehicle is in 2-wheel drive mode, eliminating the need to disconnect them manually. It also engages the front axles to the differential when 4-wheel drive is selected
Air Down - Partially deflating tires to improve traction
Air Locker - Pneumatically-activated differential locker
ARB - Manufacturer of high-quality aftermarket 4x4 accessories, including their patented air locking differential as well as armor for all areas of your 4x4
AT-PZEV - Advanced Technology Partial Zero Emission Vehicle; vehicles that produce extremely low levels of hydrocarbons and oxides of nitrogen
A-TRAC - Active Traction Control; incorporates sensors at all four wheels to monitor a loss of traction, Active TRAC employs brake and throttle control to reduce wheel spin and transfer torque to the wheel with the most traction.
Auto LSD - Automatic Limited-Slip Differential; differential that automatically distributes power to the wheel that has traction, this type of differential is preferred in slippery conditions (snow, ice, gravel, etc...)
BFG - B.F. Goodrich Tires
CAI - Cold Air Intake
CARB - California Air Resources Board
Cat - Catalytic converter; exhaust device installed before the muffler to reduce emissions (Cali-spec models have dual cat's)
Cat-Back - Exhaust system after the catalytic converter
CEL - Check Engine Light
CHMSL - Center High-Mount Stop Lamp
COG - Center of Gravity
CRS - Child Restraint System
CV - Constant Velocity
DAC - Downhill Assist Control; system that automatically applies the brakes during a downhill descent without locking the wheels

GPS - Global Positioning Satellite
GVWR - Gross Vehicle Weight Rating; total weight including the vehicle and its equipment, fluids, occupants and cargo.
HAC - Hill-Start Assist Control; automatically increases brake pressure to all four wheels to reduce rolling backwards while accelerating uphill.
HID - High Intensity Discharge; extremely bright, often blue in color, low-wattage lights
IFS - Independent Front Suspension
LCA - Lower Control Arm
LCD - Liquid Crystal Display
LED - Light-Emitting Diode
LEV - Low Emission Vehicle
Live axle - Straight axle (non-IFS)
Locker - Device put in differentials to lock gears together providing exceptional off-road traction.
Locking Hubs - Engage-able free-spinning front hubs (i.e. Aisin manual hubs); preferred due to the ability to reduce wear on components when 4-wheel drive is not engaged.
LSD - Limited Slip Differential; type of differential that improves traction by splitting torque evenly and preventing one wheel from slipping or spinning, this type of differential is preferred in slippery conditions (snow, ice, gravel, etc...)
LSPBV - Load-Sensing Proportioning and Bypass Valve; mounted to the frame and the rear axle, the LSP & BV senses the weight distribution of the vehicle and automatically varies the amount of hydraulic pressure to the rear brakes based on the load in the vehicle, this helps to reduce rear-wheel lock-up with either light or heavy loads to maintain stopping control.

SULEV - Super Ultra Low Emission Vehicle
TPMS - Tire Pressure Monitoring System; alerts the driver by illuminating an indicator on the dash when tire pressure reaches a critically low level
TRAC - Traction control; helps to avoid slippage of the driving wheels by slightly applying the brake on a slipping drive wheel and reducing the throttle to maintain traction according to the road surface conditions.
TRD - Toyota Racing Development
TSB - Toyota Service Bulletin
UCA - Upper Control Arm
ULEV II - Ultra Low Emission Vehicle II
Unibody - The floor pan of a vehicle and chassis are connected to form a single structure; there is no separate frame. By welding all body panels together to form the vehicle's frame, it is possible to build in strength and rigidity with less weight.
URD - Underdog Racing Development; manufacturer/distributor for various aftermarket performance parts including the TRD Superchargers
VSC - Vehicle Stability Control
VVT-i – Variable Valve Timing with Intelligence; varies the timing of the intake valves by adjusting the relationship between the camshaft drive (belt, scissor-gear or chain) and intake camshaft. Engine oil pressure is applied to an actuator to adjust the camshaft position.
WOT - Wide-Open Throttle
Y-pipe - Pipe used to split/bypass the exhaust

Got bored last night, did a little Google'ing and research on Wikipedia.

I added a crap ton of terms and lingo.
Check it out and see if I forgot anything.

I compared a lot of it to the Toyota Corporate Glossary on their website and I think we're good.
