To flash an ECM (Engine Control Module), you typically need a compatible diagnostic tool or software specific to your vehicle's make and model. Connect the tool to the vehicle's OBD-II port, then follow the software instructions to upload the new firmware or calibration file to the ECM. Ensure the vehicle's battery is fully charged and do not interrupt the process, as this could corrupt the ECM. After flashing, verify that the new software operates correctly by running diagnostics.

Why would the computer on a 87 firebird not flash codes?
It won't flash any if there aren't any to flash. It should at least flash code 12 when you use the test terminals. If it doesn't then you probably have a bad ECM. Make sure that you have power going to the ECM first. Most of the GM cars have a power wire running from the battery directly to the ECM. Make sure this is connected and the ECM fuse is good.

Where is the cp hook up at in a 94 Isuzu truck?
I have 94 Isuzu pickup with 265,000 miles. There is no cp or ecm plugin to check your trucks brain. Your truck has a OBD-1 system. These types have a self check system. To start you must find the codes that will flash on your (check engine) light. Theres a kick panel on drivers side below, remove it. You will see the ecm box. Below it you will see the Data link connector (White wire) and a ground lead (Black wire) are used to access trouble codes. With ignition on and engine off, connect leads together. The Check Engine light will first flash Code 12 three times, then light will flash any other trouble codes stored in ECM memory. If related fault does not reccur within a certain time frame, the trouble code will be erased from the ECM memory. I hope this gets you started.
