I just aquired a Diagnostic Scanner that has readiness tests on it but I can not figure out what the tests are???:confused: (I tried searching but can't find anything.) The test says T=06 c=35 fail
Hi 001c <=0048


What dose it mean?????:confused: :confused: :confused:

Who made the scanner?
It might be a hardware code from the scanner.?.

I use this one and it's a nice set up for 130.00

Mine is an auto x-ray. The Code is from the readiness test that is dose on the vechile.

ok what kind of car ur truck is it?

99 TJ 4.0L but it has simlar codes for other obdii vechials. I would really like a listing of what the tests mean.:D :D

Do you have a list of Jeep codes? I read the 84 page manual and it was no help. Have you sent tech service an e-mail?

This is pasted fron the site listed above.
Located in the FAQ area.


Q: My scanner says "Readiness Tests, "Not complete".
A: The Readiness Tests are on-board diagnostic tests run by the on-board computer to comply with Federal OBD-II regulations. These tests must be completed in order for the vehicle to establish whether or not it is inside the emissions standards set by the government. The AutoXray Scanner gives the results to these tests, and displays the overall result during a scan and the individual readiness tests under the MON key menu.


Q: I lost my manual, what now?
A: AutoXray's manual is on line, find it at Download EZ-Link Manual (Adobe PDF)

Yea I've already talked to them and searched thier site. The way I understood it the readiness tests were standardized.:confused:

I think my ? is misleading it completed the readiness test and and it passed the others but failed this one. (the check engine light is on) it also has p301 error code stored which is misfire on Cyl #1.

OK, this means that the Truck is out of legal specs on emmissions.
The Readiness check is standardised cuz it is based on the government regs on how much the truck can pollute in "Parts Per Mile". The OBD I specs were in "Parts Per Million".
OBD I was pretty much a reactive hardware driven system and OBD II is mainly software driven as it needs to "figure out" the Parts Per Mile emmissions as they can't really be measured but must be extrapolated by the soft ware.

So, if you fix the P301 code... the other code will go away after the truck goes through 2(?) drive cycles without failing the emmissions standards.

FYI general emmission codes are also standardised on OBD II.
So, Mercedes and Chevy have the same "general" codes but they both have their own specific codes and your scanner would need the specific software to read these, but, you can read every manuf. general OBD II codes.

Hope this makes sense....:D

#1 misfire can be either ign. or fuel related...
Have you had or done a fuel rail cleaning???

Cool, Thanks


Is there anywhere I can find out what those test are???

I under stand the connection but I though that this might provide additonal info.

You need a good shop manual.
From the dealer is best.
These tests are all in the software of the OBD II system.
You need a trouble shooting "tree"/flow chart if you want to properyl fix this stuff.

Example: The OBD II system can and will pressurize your fuel tank and monitor the pressure to check for leaks in you Evaporative Emmissins System. You will get a code if your gas cap is on loose.
There is no way for you to check this "test" you just need to understand the system and know where to look....what may cause a problem...what to try to fix it...

If you just read a code and head for the parts store... you would probable buy an vapor canister purge solenoid and you really needed to tighten the gas cap.;)

So, your brain is your best tool.

Gone is the "grease monkey" ENTER the "tech."

You can test parts but you can not run the test that OBD II will do.

I will check out the trusty fsm when I get home, I did not see any codes like that, so it confused me. So there is now way to decifer what T=06 c=35 fail Hi 001c <=0048 was doing that failed.

The P0301 is a standard SAE diagnostic trouble code (DTC) for misfire on #1. The values "T=06 c=35 fail Hi 001c <=0048" are a snap shot of the values of the particular sensors when the DTC was set. The factory service manual may have the meaning of these terms, but they don't always want end users to have easy access to this information.

Here is a site for most of the SAE and manufacturer-specific DTCs

Pin head is correct. Whenever an OBDII code is set it takes a freeze frame and failure record. WHich basically gives you information from when the code set, and information from when it last failed or passed.
I believe a factory scanner would decifer it more clearly.
I would not worry about that information, Just fix the problem with the missfiring on cyl #1 like Lord Baskerville said and the code will go away after two passed tests for that code.

P.S. I don't believe a factory maunual with decifer the output of that scanner, factory maunuals usually only cover info from their scanner. I am guessing the scanner you have didn't write software to decifer those records, just the DTC codes.

Mine is an auto x-ray. The Code is from the readiness test that is dose on the vechile.

The Readiness monitor is a check the onboard computer does, basically it boils down to two states: Not Set, and Set (pass/fail). Your code reader does not do these tests, it only shows what the onboard computer has determined the monitors to be
