If this is an OBD scanning tool for automotive, there is a fuse that powers the OBD scanner jack. It is a 5 amp fuse and when it blows out, the scanner wont work. Check the fuse box

98 chevy astro changed egr and catalytic con and airfilter,gas cap,and0n the obd2 scan tool it shows no trouble codes it shows catalitic inc and evap inc.


I think your scan tool is showing that the monitors
for the Evap System have not run yet,thus incomplete

The evap will only run every few days & only if driven
for some time.

The O2 Sensor Data should be on the scan tool

I would replace the front ones if they have 100,000
miles on them

I would look at short term fuel trim also,most likely
it will be 3 or 4 % Pos or Neg & Switching

An Oscilloscope is the only way to look at an O2 Sensor
as far as I have found. A volt meter is a waste of time & won't
give you switching counts in real time

The Converter won't be complete until it warms up to
at least 850 deg or more

You do not have another master ? If not you need a factory scan tool Dealer or mobile lock smith .
Connect a scan tool to the vehicle.
Turn ON the ignition, with the engine OFF.
Insure that all power consuming devices are turned OFF on the vehicle.
With a scan tool, select Request Info. under Service Programming System and follow the scan tool on-screen instructions.
Disconnect the scan tool from the vehicle and connect the scan tool to a Techline Terminal with the current Service Programming System (SPS) software.
On the Techline Terminal, select Service Programming System and follow the Techline Terminal on-screen instructions.
Disconnect the scan tool from the Techline Terminal and re-connect the scan tool to the vehicle.
With a master passkey III key, turn ON the ignition with the engine OFF.
With a scan tool, select Program ECU under Service Programming System.
At this point the scan tool must remain connected for the duration of the 10-minute relearn procedure.
Important: On some vehicles the SECURITY telltale maybe illuminated on steady for the duration of the 10-minute relearn procedure.
Observe the scan tool, after approximately 10 minutes the scan tool will display "Programming Successful, Turn OFF Ignition". The vehicle is now ready to relearn the key information and/or the passwords on the next ignition switch transition from OFF to ON.
Turn OFF the ignition and wait 5 seconds.
With a master Passkey III key, start the vehicle. The theft deterrent control module has now learned the key transponder information and the PCM has now learned the fuel continue password.
Important: Perform this step ONLY on vehicles with EXPORT and Canadian configured theft deterrent control modules.
Turn OFF the ignition and wait 15 seconds minimum.
