Does it actually say inf resT ??

early 90's cars are infamous for this light staying on. It seems that there are two sensors, one on the frame underneath the battery box, and one underneath the windshield washer container. Both bolt directly to the frame. These little electronic wizards detect a crash via vibration in the frame, and then set off the air bag.
The problem is two fold.
First, their location promotes getting water on them.
Secondly, the water causes a corrosion problem between the sensor and the frame. These little wizards are so sensitive to corrosion, 1/2 of one ohm of resistance that developes between it and the frame will send a fault light code to the computer, and trigger the trouble light. Most of the time, the air bags are still functional, just the light is on.

    Here is a little more tech. Lingo I found...



    The "Inflatable Restraint" is a common occurrence especially on the '90 model year. Any time the light illuminates, a code is stored within the Central Control Module (CCM). If the code stored indicates a sensor problem, the common occurrences are a faulty sensor ground or faulty sensor(s). These sensors are located on each front frame rail just in front of and under the battery, and equal distanced on the right side. These sensors can be removed, the frame and sensor sanded for cleanliness, and reinstalled using a small amount of dielectric grease. If the light persists, then a sensor replacement is most likely necessary. Be sure to disconnect the battery and ensure that the ignition is in the off position prior to working on the Supplemental Inflatable Restraint (SIR) system.


    Note: Operation of the SIR system will be questionable if the "INFL REST" light is illuminated.

What light is on when charging?


Generally speaking for all models of autos, no light is on when the battery is properly charging. Light comes on when there is a problem and with "dummy" lights in dash array, a little battery icon lights up. Need more definite info to properly answer your question.

How do you reset security system in 2004 dodge neon


Try pressing down on the red security light on the dash and hold it down for about 3-5 seconds. Sometimes Neon's just have a dummy light on the dash that isn't actually hooked up to anything, but its a good place to start.

2006 Cobalt. ABS and TC dummy lights appear once in a while. Seems like it happens more when temperatures are hot outside. Doesnt come on when its cool during my morning commute


There are no dummy lights on a vehicle

Any light you get on your dash is a warning to
direct you to at least check for codes in a day
or so, & decide if continuing to drive it is a good
idea

Almost every time your get any light you have a
failure in some system & the lights are not going
away until the car is repaired

The ABS & Traction Control System is explained in your
owners manual & any repair shop can diagnose those issues

The system should no be temp sensitive unless the electronic
abs module was somehow the problem
