OBD Trouble Codes

The Supplemental Inflatable Restraint (SIR) system supplements the protection offered by the driver and front passenger seat belts. The SIR system deploys an air bag from the center of the steering wheel and from the right side of the instrument panel. The knee bolsters and the steering column absorb crash energy. The driver and passenger knee bolsters are below the instrument panel.
Here is a list of some common codes that will be stored in the computer if the warning light comes on:

The catalyst within the converter promotes a chemical reaction which oxidizes the HC and CO present in the exhaust gas, converting them into harmless water vapor and carbon dioxide. The catalyst also reduces NOx, converting the NOx to nitrogen.
