Won't pass NYS Inspection, and I get this on my scan tool?!

[Blk04Snake]

I had read here that others had troubles getting their cars inspected with the new NYS inspection machines we got earlier in the year. I decided to get my car done a month early just in case there was a problem, and glad I did!

Friend works at a shop so I had him take the Cobra to work today to inspect it and he calls me at lunch time and says that it won't communicate with the inspection machine. So tonight when I got home from work I put my scan tool on it because I know that the machine will show no communication if some of the monitors are turned off. I wanted to see what was turned on and off in the tune.

Here's what I get on my scan tool screen:

So now what do I do?!?

I know I can load stock tune with my Predator and get it inspected, but what do I do after? Looks like something is really messed up here. I'm running 2.8 pulley, Magnaflow catted X, CAI.. nothing major.

Thanks all!

all your monitors are shut off? without getting really into it, basically we got new software. You need a new tune. with your mods though, you should pass easily

 

[Blk04Snake]

No, they shouldn't be shut off is the problem. I had this discussion with the tuner when he tuned the car in 2011 and it's passed in 2012 and 2013 on the old NYVIP inspection machine and now I get this code and none of the monitors show up. And it won't communicate with the new NYVIP2 machines.

This code shows up on all tuned mustangs. Or at least any tuned mustangs that have had revs/mile or rear gears changed in the tune as both of those are items in the VID Block and your tune tells the ECU to ignore them.

HOWEVER, if you can't read any monitors, it is possible you legitimately have a corrupt ECU. It'll have to go the dealer for a reflash if this is the case.

 

[Blk04Snake]

Well.. I loaded the stock tune back into it today and now that code is gone and I have 3 of 8 monitors set. Guess I'm going to have to drive it some to get the rest set so it will hopefully pass.

Then find a new tuner that will tune the car correctly so this doesn't happen again.

So what would be the fix for cars with rear gear changes that cant go back to the stock tune? I'm only asking because CA has these machines also, my gt has 3.55s and i had to have the tune adjusted. No way I can go back to a stock tune because the car is now supercharged.

I don't live in CA so I can't say for sure, but generally that code won't fail you. They're generally looking specifically at emissions-related codes...like cats, and the evap system.

I guess I miss understood you then. I thought you were saying his ecu couldn't communicate with the state computer because of this code.

 

[Blk04Snake]

I'm not sure if the machine would fail it because of the code or not. No check engine light was displayed or commanded. However, it also wasn't displaying/running monitors and I know with the new machines it will fail it for sure this way.

All well so far with the stock tune loaded. On a 2001 or newer vehicle in NY we can only have one monitor not set to be able to pass and as of tonight the only monitor that hasn't set yet is Catalyst so I should be good to go on Monday.

Then I will need to figure out who to take the car to so I can get a good tune put in it that won't mess with the inspection again next year.

I have no cats and no egr and I passed

I have no cats and no egr and I passed

And what kind of tune do you have? When did you have it inspected last? New inspection machines started in about November of last year and are a PITA!

^^^Would like to know the secret around that?

 

[po-po 5.0]

I guess I miss understood you then. I thought you were saying his ecu couldn't communicate with the state computer because of this code.

All I'm saying was that this particular code is normal for any ECU with a flashed tune that adjusts revs/mile or rear gears, and might be normal for ANY flashed tune. This code alone won't fail you for emissions. Also, having this code doesn't necessarily mean that the ECU is corrupt, but the fact that his ECU won't communicate with the testing computer means it might actually be corrupt.

2003 PCED OBD SECTION 2: Diagnostic Methods
Procedure revision date: 12/19/2002

--------------------------------------------------------------------------------

Flash Electrically Eraseable Programmable Read Only Memory — Flash EEPROM
Description
Flash Electrically Eraseable Programmable Read Only Memory (EEPROM) is contained in an Integrated Circuit (IC) internal to the PCM. The EEPROM contains the vehicle strategy including calibration information specific to the vehicle and is capable of being reprogrammed or reflashed repeatedly.

As part of the calibration there is an area referred to as the Vehicle Identification (VID) block. The VID block must be programmed when replacing the PCM as described under Programming the VID Block for a Replacement PCM. Failure to perform this procedure may generate fault codes: P1635, P1639, VID Block not programmed or is corrupt. The VID block in an existing PCM can also be tailored to accommodate various hardware/parameter changes made to the vehicle since production. Failure to perform this procedure properly may generate fault code: P1635, Tire/Axle Ratio out of Acceptable Range is one of the main causes for code: P1639. This is described under Making Changes to the VID Block and also under Making Changes to the PCM Calibration. The VID block contains many items used by the strategy for a variety of functions. Some of these items include the VIN number, octane adjust, fuel octane, fuel type, vehicle speed limit, tire size, axle ratio, the presence of speed control and four wheel drive electronic shift on the fly versus manual shift on the fly. Only items applicable to vehicle hardware and supported by the VID block will be displayed on the scan tool.

When changing items in the VID block, the strategy will place range limits on certain items such as tire and axle ratio. The VID block is also limited to the number of times to be reconfigured. When this limit is reached, the scan tool will display a message indicating the need to flash the PCM again to reset the VID block.

Each of the procedures described below use the Worldwide Diagnostic System (WDS). Reprogramming can be performed by a local Ford dealer for any non Ford facility. There are other Enhanced Scan Tools that may have reprogramming capabilities available. Refer to the manufacturers users manual for details.

Programming the VID Block for a Replacement PCM
A new PCM will contain the latest strategy and calibration level for a particular vehicle. However, the VID block will be blank and will need programming. There are two procedures available. The first is an automatic data transfer from the old PCM to the new PCM and the second is manual data entry into the new PCM.

Automatic data transfer will be performed if the old PCM is capable of communicating. This is done by the use of a scan tool to retrieve data from the old PCM before removing it from the vehicle. The stored data can now be downloaded to the new PCM after it has been replaced.

Manual data entry must be performed if the old module is damaged and/or incapable of communicating. Remove and replace the old PCM. Using a compatible Scan Tool select and execute Module/Parameter reprogramming referring to the manufacturers users manual. Important, make certain that all parameters are included. Failure to properly program Tire Size in revolutions per mile, (rev/mile = 63,360 divided by the tire circumference in inches) Axle Ratio, 4x4/4x2, and/or Manual/Electronic shift on the fly (MSOF/ESOF) may result in codes: P1635, P1639. You may be instructed to contact the "AS BUILT" data center for the information needed to manually update the VID block with the scan tool. Contact the center ONLY if the old PCM cannot be used or the data is corrupt. For Ford L-M technician's, contact your National Hotline or the Professional Technician Society (PTS) web sight for "AS Built" data. Non Ford technicians, use the Fed World website at "fedworld.gov". Select Auto Service Information and search for "Calibrations" or "Vehicle Calibrations" then specify vehicle manufacturer, model name and model year as required.

Making Changes to the VID Block
A PCM which is programmed may require changes to be made to certain VID information to accomodate vehicle hardware. Refer to PCM/Module Reprogramming on the Scan Tool.

Making Changes to the PCM Calibration
At certain times, the entire EEPROM will need to be completely reprogrammed. This is due to changes made to the strategy or calibration after production or the need to reset the VID block because it has reached its limit. Refer to PCM/Module Reprogramming on the Scan Tool.

Had the car inspected last month and I have a sct tune

Had the car inspected last month and I have a sct tune

real key is what the monitors are set in the tune.


The issue has become somewhat widespread for modded cars in NY

 

[Cobrasmith87]

When I first got my vmp blower my car was not passing when back to the shop that works on my car and messed with the tune and now I pass with no problem if u want to know the name of the shop pm me
