For vehicles after 1996, returning the check engine light codes in your dash panel is simple. All you need to do is find your diagnostic connector located under the dashfrom the the driver side . Then you can connect the scanner and the code will be displayed for you. If you do not have any scanner like most drivers, you can bring your vehicle to any local auto parts store and they will usually scan the codes FREE for you. However, for vehicles on or before 1995, there is only one cheap way to get it: You can do it yourself
!On Board Diagnostic (OBD) was designed on vehicles equipped with electronic fuel injection, so you can generally retrieve the codes yourself. No need to buy a scanner or running at all parts stores check engine light. This system is called obd1 and applies to most vehicles made before 1995 to about 1993 domestic and import. In this article, I will discuss methods used by domestic vehicle manufacturers on how to check engine light in their cars and trucks.
for domestic GM vehicles were before 1995, the diagnostic connector located under the driver side dash panel. To get the check engine codes to flash in your dash panel, use the jumper wire or paper clip and connect terminals B and diagnostic connector. Turn the ignition key on engine off and the codes should start flashing. All codes should start with a 12 that was one long flash after 2 short flashes. The number 12 means the diagnostic system is normal and will constantly be repeated, if there are problems of codes. Otherwise, the number 12 will flash three times before flashing error codes.
Ford owners can check their lights to check using the diagnostic connector located in the engine compartment of the fender near the battery motor. Getting the obd1 codes need a few tools: a 4 inch long gage 16 jumper wire and 12 volt test light.
Both tools are hooked into the diagnostic connector and when the ignition key turned on (without starting the engine) codes will start to blink in a test light, not in the dash panel. If no password, you will usually get a number 11 or 111th On the plains, there are 2 ways to test, KOEO (key on engine) and koer (key on engine running). Both testing methods should be used to get an accurate assessment of fault codes stored.
Of all the 3 domestic vehicles, the easiest way to check engine light is Chrysler products. Why? For all that is required is that the ignition key on and off within 5 seconds, and the code will start flashing in the dash panel.
Calculating codes are flashed is almost the same for the three domestic cars, and most of the codes can be erased or cleared by disconnecting the battery negative terminal for 1 minute and again. Just be sure to check your service manual in case you have electronic equipment such as radio or clock that needs reprogramming in which battery disconnection is not recommended. Finally, after carrying out repairs on the culprit code, always go for a road test to verify that the problem is resolved.
