The dealership replaced the Aux Battery, a couple of weeks ago. The Jeep runs and acts great now. So, it was.time to get the State inspection done. They said it fail the inspection, because they said it showed the computer had been disconnected, and needed to be driven 50-150 miles, so it could reset itself. Has anyone else heard of this, or had this happen??

@DaltonGang

This is the norm. IF, this was not a requirement, a guy could clear a code and go right over and get a problematic vehicle to pass inspection... a vehicle that would otherwise fail inspection.

There is normally a published procedure (driving speeds/time) to get the sensors to all trigger ready.

Did they tell you which one(s) still wasn't "ready"?

First result from Google:

All Monitor Drive Trace

Pre-Conditioning Requirements:

>> MIL must be off

>> Cold start (Note: cold start temperature is undefined)

Driving Procedure :

1) Warm engine up for five minutes (must reach closed loop)

2) Drive (with steady throttle) at a speed between 40 and 60 mph for 8 minutes.

3) Stop and idle for 3 minutes.

4) Drive (with steady throttle) at a speed above 20 mph for 2 minutes.

5) Turn key off, leave off for ten minutes (to run O2 sensor heater monitor).

Note: Due to the limited preconditions provided with this drive trace, NCVECS recommends using the monitor specific drive traces for Chrysler vehicles.

Catalyst Monitor Drive Trace

Pre-Conditioning Requirements:

>> MIL must be off.

>> No DTCs present.

>> Fuel level is between 15% and 85% full.

>> ECT above 70º F.

>> Engine must have run at least 90 seconds

>> Engine between 1,350 & 1,900 rpm.

Driving Procedure :

1) Idle vehicle for five minutes (to reach closed loop operation).

2) Drive with a steady vehicle speed between 30 and 45 mph for 2 minutes.

EGR System Monitor Drive Trace – Vacuum controlled

Pre-Conditioning Requirements:

>> MIL must be off.

Driving Procedure :

1) Idle vehicle for five minutes (to reach closed loop operation).

2) Drive with a steady vehicle speed between 40 & 60 mph for 8 minutes.

EGR System Monitor Drive Trace – Electronic

Pre-Conditioning Requirements:

>> MIL must be off.

>> MAP must be between 0-60 KPa.

>> Engine speed between 500-850 rpm.

>> ECT is above 180º F (90º C).

>> No misfire temporary (pending) or matured fault present.

>> A/C clutch, PS Switch and Cooling fans do not change state (turn off).

Driving Procedure:

1) Idle vehicle for five (5) minutes (to reach closed loop operation).

2) Drive with a steady vehicle speed between 40 & 60 mph for 2 minutes.

3) Idle vehicle for three (3) minutes.

Note: This monitor evaluates EGR flow based on a change of engine roughness (idle stability). Conditions causing un-stable idle will prevent this monitor from running.

Evaporative System Monitor Drive Trace
Trace 1: Standard Type – Make sure that your fuel level is between 50% and 85% full.
Idle for 5 minutes
Smoothly accelerate and maintain a speed between 30 to 45 mph for 2 minutes.

Trace 2: Leak Detection Pump
From 6-8 hours of the vehicle being off (cold soak), idle for 5 minutes
Drive in city traffic naturally with stops and acceleration for 5 minutes.
Stop. Idle vehicle for 4 minutes.

O2 Sensor Monitor Drive Trace
Idle for 5 minutes
Smoothly accelerate and maintain a speed above 25 mph for 2 minutes.
Stop and idle for 30 seconds.
Smoothly accelerate and maintain a speed between 30 to 40 mph
Repeat idle and acceleration to 30-40 mph five times.

O2 Sensor Heater Monitor Drive Trace
Idle for 5 minutes, then shut the engine and leave the vehicle off for 10 minutes.

@GATORB8

In the case of a State Inspection, the above criteria(s) for each system, is not what the issue is... why the yearly, State Inspection is a no go.......

It's just the simple fact that the PCM has been reset and has not met the criteria in regard to time/driving. Keeps a guy from doing a reset/clearing codes and going in for State inspection before code is thrown again thanks to the vehicle being problematic.

That's not my experience (at least in a similar situation in IL), they say that, but the real reason is there is still a sensor not in ready state. The reset starts the readiness tests again. They say to drive 50-100 miles because they figure that will be enough to trigger them.

Here in CA if you disconnect battery for more than about 30 seconds on any modern vehicle the codes go crazy and it will not pass smog. And yes now you have to do what the inspection tech said. You are lucky. Some vehicles (like a Toyota) have to be driven over 250 miles to reset the codes.

Totally normal, the computer is cleared and needs to record emissions data again.

Yes.

A neighbor of mine was chasing his tail regarding an emission issue on his Dodge Dakota. I'd go over with my code reader, pull the code(s) and then extinguish the light on the dashboard. We discovered that the underlying CEL code(s) wouldn't be erased from the vehicle's computer until it was driven +/- 100 miles without the same problem(s) reoccurring.

IOW, turning the dash light off with my code reader wouldn't hide the problem from a dealer's more advanced scanning equipment, if the problem wasn't resolved in any fashion. You seem to have discovered this the hard way.

We ended up identifying and replacing a majority of emission fitments on that truck, and erasing codes that kept reappearing, until a small and hidden part (somewhere near the fuel tank, IIRC) was replaced that finally fixed things once and for all.

The good news is that if your Wrangler is truly up to snuff, the solution is simple as driving it up to and perhaps just past the mileage reset point.

Completed a drive cycle with my S10 before, but never a jeep (I do it every year).
Check their website, there should be a process where you do something like drive to 60MPG and then let the foot off the gas until you hit 10MPG, and such stuffs.

Try this:

Question re the Tazer and Security Gateway.

I assume you need to remove the Tazer and reconnect the SGW so the OBDII scanner can work during the test.

Is disconnecting the Tazer and reconnecting the SGW going to flag the vehicle as not ready to test?

I notice that when I read the codes after unpluging the Tazer a "Security Gateway Unplugged Event" will be reccorded.

Anyone knows? Thanks.

i would make sure that the Powertrain Control Module (PCM) is not faulty.

Prior to getting my Jeep registered when i first took ownership, i took it to the dealer to have the upgraded software installed as part of the clutch recall. Then when i went for an Emission’s test (which is required in Missouri to register a car to its new owner) it did not pass. They told me to drive it and bring it back (due to unsatisfied sensors, EVap, O2.) and all of that bs. I drove it for >200 miles doing all of those stupid drive cycles and it still would not pass. I then took it to a different Jeep dealer and they told me that the PCM was bad which was keeping the emission's inspection from passing. Due to Covid, the damn part was on back order so i had to wait for nearly 3mos. this was truly a headache..

You mean due to Jeep prioritizing new builds vs having enough spare parts inventory for after sales support, right?
