called that, because not only do they control the engine management system, but also is capable of performing a self-diagnostics of the engine management For example, the ECM (Electronic Control Module) uses the Oxygen Sensor (O2 Sensor) to monitor exhaust gas for being to rich or http://www.freeautomechanic.com/diagnostictroblecodes5.html lean. If the computer feels that the conditions are right for the sensor to be malfunctioning, it will set a DTC 13 (O2 Sensor circuit fault). Once a DTC is set, the Check engine light will illuminate. There are many acronyms for the Check engine light such as CEL, MIL, SES, but we will use CEL (check engine light). How do I pull DTC's? This is simple. You don't even need an expensive scan-tool or code reader, just a simple paper clip. Locate the error codes ALDL (Assembly Line Diagnostic Lead). It is usually under the drivers side of the dash. It may have a cover over it, and may even say "Diagnostic Connector". This is the ALDL. The two terminals that you need to be concerned with is in the picture. It is terminals "A" and "B". Simply turn the Ignition to "Run" (Do not start the vehicle) and put the paper clip in the two terminals. Now watch your CEL. It will start flashing. It will look like Morse chevrolet error codes Code, but it isn't, and is real easy to interpret. The first code that will flash will be a code 12. It will be "flash, pause, flash, flash, pause, pause," and repeat the cycle three times. The ECM will flash each code three times, and move on to the next. If you have no codes stored, it will keep flashing code 12. Code 12 simply tells you the ECM is not receiving any pulses from the distributor (since the car is not running). If you pull codes with a scantool and the car is running, this code will not show up. Its no big deal, it lets you know the ECM is in the "Field Service Mode" You will also notice the cooling fans come on, this is normal. Vehicle Specific Auto Repair Manual Code Diagnostics What do I do with the Codes? This is less simple. OBD-I codes are very vague, and diagnosis sometimes isn't that simple. Most people think that a code 32 (EGR system) means the EGR valve is bad and needs replaced. This isn't always so!!! There are many components in the EGR system that could cause the code to set OTHER than the EGR valve itself! Below is a list of codes and what they mean. Code: Meaning: 12 No Distributor pulses 13 Oxygen sensor 14 Coolant Temp sensor circuit 15 Coolant Temp sensor circuit 21 Throttle Position Sensor 22 Throttle Position Sensor 23 Manifold Air temperature sensor 24 VSS (Vehicle Speed sensor) 25 Manifold Air temper
