Car Pictures And Videos - Dash Warning Light Symbol Descriptions

Pictures and descriptions of some common dash warnings.

 Description of the ABS warning light that can come on your car or truck. There are many sensors that can turn on this indicator. A warning light means a problem was detected, and the system needs to be scanned for codes in order find out the area the fault is in. With the light on,  ABS operation is not present, but normal braking is.
ABS Warning Light
 The supplemental inflatable restraint (SIR) system supplements the protection offered by the occupant seat belt system. The SIR system has several inflater modules located throughout the vehicle, i.e. The inflatable restraint steering wheel module, inflatable restraint IP module in passenger side of dash, and the inflatable restraint side impact module - LF and RT. Each inflator module has a deployment loop that is controlled by the inflatable restraint Sensing and Diagnostic Module (SDM), which is mounted inside of the vehicle. A problem in any part of the system will turn on the light.
SIR Airbag Warning Indicator
 The security system on todays cars and trucks prevents the vehicle from being stolen. There are many variations of the system going back to the early 1990's. This warning could be on when the engine is running, indicating a fault has been detected in the system. If left unrepaired, there is a good posiblity that the car will eventually not start.
Theft Security System Light
 This light comes on for the reasons below, as well as other related system problems... The electronic brake control module (EBCM) detects a malfunction in the traction control system. The IPC receives class 2 messages from the EBCM requesting illumination of both the service vehicle soon and traction off indicators. The body control module (BCM) detects certain malfunctions in the lighting system. The IPC receives a class 2 message from the BCM requesting illumination. The IPC sends a class 2 message to the BCM indicating that the service vehicle soon indicator is illuminated. The BCM sends a class 2 message to the radio in order to activate an audible warning. The IPC detects a loss of class 2 communications with the BCM. Or any number of exterior light problems, such as daytime running lights (DRL).
Service Vehicle Soon Indicator
 Todays vehicles use many sensor, switches, solenoids, and other electrical components to control or monitor every aspect of the engine. From controlling the fuel and ignition systems, to monitoring the emissions. A problem in any of these systems, or subsystems, can cause the check engine light to come on.
Check Engine | SES Light
 The tire pressure monitor system in todays cars use a radio frequency (RF) transmitter ( Tire Pressure Sensor ) in each wheel valve stem to relay pressure information to the module. The Service Tire Pressure Monitor System light / warning blinking means there is a problem in the system, not a low tire.
Tire Pressure Monitor System
 When this is on, the traction system is disabled. A problem in the ABS system is usually the cause, and would have to be scanned for codes.

Does My Car Need A Front End Alignment?

Why should you get a front end alignment? Improper front end alignment is a major cause of premature tire wear. Over years of driving, a properly aligned vehicle can add thousands of miles to the life of your tires. Most tires are replaced because of premature wear caused by the front end being out of alignment. When the front end is line properly, this makes it easier for the car to roll. Read more...
