What does INC mean on a OBD scanner?
What does INC mean on a OBD scanner?
On your scan tool, for monitors which your vehicle is equipped with, you should either see an “INC”, representing Incomplete, or “READY”, indicating the monitor has passed its self-test and is ready for inspection.
Why is my OBD not working on my catalytic converter?
The OBD II system can’t evaluate the converter if the upstream and downstream O2 sensors are not functioning normally. So any O2 sensor problems have to be dealt with before you can use the OBD II system to diagnose the converter. O2 sensors typically fail because of old age or contamination.
How are O2 sensors and catalytic converter diagnostics fail?
O2 SENSORS & CATALYTIC CONVERTER DIAGNOSTICS Converters typically fail one of two ways: they get too hot, melt and plug up, or the catalyst becomes contaminated and useless.
Why does my Dodge Dakota not pass smog inspection?
I had to drive more miles, totaling 160 miles so far, but the catalyst OBDII monitor is still not ready and I can’t pass the smog inspection. Replacing the battery or having simply disconnected the battery on your Dodge Dakota caused the engine control unit (ECU) to reset and clear all the emission monitors (and trouble codes; if any existed).
How can I tell if my OBD 2 car has an emissions problem?
An OBD II vehicle with a converter efficiency code may or may not have an emissions problem. The only way to know for sure is to give it an emissions test. But here’s the catch. Even if it passes a tailpipe test, it may not be emissions legal as long as the MIL lamp remains lit.

What does the DTC light on an OBD mean?
If a problem is detected, a Diagnostic Trouble Code (DTC) is set, and the computer turns on the “Check Engine” light. (The light may say “CHECK ENGINE”, “SERVICE ENGINE SOON” or merely be an icon that looks like an engine.)
