Just had the AQ flash done yesterday but am unaware of what it was for. All I was told was that it was an update.

Any info on this?

I'm finding out on the forums that I seem to be the first to have this flash done.

Thanks!

there aren't any new tsb's. As a tech we're told to load the latest version on the starscan, the computer doesn't tell us any more details. i'll definitely look into it on Monday and let ya know. I was told to by Cummins expect a new flash in October. I didn't even know about it yet.

I know he said it was AQ because I had even mentioned something about the AP flash and the visor doohicky.

Also, where do I look for the sticker under the hood?

NOTE: This bulletin applies to vehicles equipped with a Cummins 6.7L engine (sale
code ETJ) built on or before February 14, 2008 (MDH 0214XX).
NUMBER: 18-013-08
GROUP: Vehicle Performance
DATE: March 13, 2008
SYMPTOM/CONDITION:
NOTE: The following conditions and improvements have been addressed with the
latest Engine Control Module (ECM) software. This Service Bulletin (SB) only
addresses the labor associated with the reprogramming of the ECM, the
CCN, and the installation of a Documentation Kit. Any other labor associated
with the performance of additional diagnostics is not addressed by this SB
and must be claimed separately.
A. ISSUES ADDRESSED BY VARIOUS ECM SOFTWARE RELEASES TO DATE:
NOTE: With this latest ECM software release listed in this Service Bulletin, the
following symptoms have been completely addressed.
1. The technician may not be able to reprogram (flash) the PCM with new application
software.
2. One of the following driveability conditions:
a. An intermittent rough engine idle and/or white smoke following initial engine start.
b. A throttle tip-in stumble at engine speeds of 1,300 to 2,100 rpm.
c. An engine hesitation at altitude of 5,000 feet between engine speeds of 1,200 to
1,600 rpm.
d. A turbocharger “chuff-like” sound during rapid deceleration.
3. The vehicle may fail an Emission Inspection Maintenance (I/M) Test because two or
more On-Board Diagnostic (OBD) monitors report that they are not ready for testing.
This condition may cause the customer vehicle to not pass an Emissions I/M test. The
following is a list of OBD Monitors that may report as not ready for testing:
a. Non-Methane Hydrocarbon (NMHC) Catalyst Monitor.
b. Nitrogen Oxide (NOx) Absorber Monitor.
c. Exhaust Gas Temperature Sensor Monitor.
d. Electrical Charging System Monitor.
e. EGR System Monitor.
f. Oxygen Sensor Monitor.

18-013-08 -2-
B. ISSUES IMPROVED SIGNIFICANTLY BY VARIOUS ECM SOFTWARE RELEASES
TO DATE:
NOTE: The following symptoms and conditions have been significantly enhanced by
the latest ECM software listed in this Service Bulletin. Always check
TechCONNECT to see if there are new or additional Service Bulletins that
may apply to a condition. If condition persists contact STAR for further
assistance.
1. The latest ECM software includes a new extended idle feature to accommodate the
extended idle times present in some duty cycles. This feature may help to reduce the
accumulation of soot in the exhaust aftertreatment system when the engine is idling for
an extended period of time. Briefly how this feature works:
a. As needed, the engine enters an idling mode which dramatically reduces the rate of
soot accumulation in the diesel particulate filter (called “Net Zero”). Further, under
extended idle periods of longer than 2 hours, the engine enters a mode which
reduces the amount of soot accumulated in the diesel particulate filter (called “Net
Reduction”). While in these modes, the idle speed increases to 900 rpm for a period
of time. The idle speed may return to normal idle speed and then return to 900 rpm
to repeat this cycle during very long idle periods.
b. These modes occur automatically provided two conditions are met. The vehicle
must be in Park (automatic transmission) or have the Parking Brake engaged
(manual transmission) for these modes to be enabled. There must also be no
accelerator pedal input.
c. After extended idling, if operation of the engine consists of light loads for short
periods of time the engine will return more quickly to the Net Zero or the Net
Reduction mode of the extended idle operation feature.
d. After extended idling, if operating the engine consists of higher loads for longer
periods of time the engine must again idle for an extended period before the engine
will return to the Net Zero or the Net Reduction mode of the extended idle operation
feature.
2. A MIL illumination due to one of the following DTC's:
a. P2000 - NOx Absorber Efficiency Below Threshold - Bank 1
b. P2A00 - Oxygen Sensor 1/1 Circuit Performance
c. P2A01 - Oxygen Sensor 1/2 Circuit Performance
Perform this Service Bulletin and the appropriate Diagnostic Procedures for the respective
DTC. If condition persists contact STAR for further assistance.
When performing the appropriate Diagnostic Procedures for this condition. Make certain
to remove and thoroughly CLEAN BOTH OXYGEN SENSORS using a clean cloth
and compressed air. Do not use any type of liquid cleaner to clean the oxygen
sensor tips. Use compressed air to remove all soot from the oxygen sensor tip that is
inside (under) the metal shield/cover. Blow compressed air into the center hole of the
sensor shield to remove soot from the sensor tip. Ensure all soot has been removed from
the sensor tip (inside the shield) and on the outside of the sensor tip shield.
-3- 18-013-08
3. After extended idling or if an intake leak is present, the vehicle operator may
experience a MIL illumination and/or an Electronic Vehicle Information Center (EVIC)
message alert due to one or more of the following DTC's:
a. P1451 - Diesel Particulate Filter System Performance.
b. P2463 - Diesel Particulate Filter - Soot Accumulation.
c. P242F - Diesel Particulate Filter Restriction - Ash Accumulation.
Perform this Service Bulletin and Service Bulletin (SB) 11-002-07. It is VERY
IMPORTANT that SB 11-002-07 be performed COMPLETELY to return the engine and
exhaust aftertreatment systems to a “like new” condition. If condition persists contact
STAR for further assistance.
4. A MIL illumination due to the following DTC:
a. P2262 - Turbocharger Boost Pressure Not Detected - Mechanical
Perform this Service Bulletin and Service Bulletin (SB) 11-003-07. It is VERY
IMPORTANT that SB 11-003-07 be performed COMPLETELY to return the engine and
exhaust aftertreatment systems to a “like new” condition. If condition persists contact
STAR for further assistance.

do you have a chip on your truck? also does your truck run any differently with this AQ flash? one other thing, what did Dodge say the update was for.
No chip. All stock. I haven't noticed anything different in the truck at all.

When I asked for the flash, I asked him if I was going to be getting the visor info and he looked at me funny and said that I was getting the AQ flash. I said, "Oh....what does that do." All he said was that it was an "update".

I'm calling tomorrow and asking for the papers on it so I can let everybody know.

jimminy, little confused how the WCM is involved with the AQ flash. I've performed this TSB and it doesn't involve reprogramming the ECM. I found the AQ flash yesterday and there is not any info attached. When we connect the scanner, the latest and "greatest" software automatically comes up. sometimes cummins doesn't tell us what the flash does. if anything comes up i'll let ya know.

Honestly, I'm as confused as you are.

When I asked for some info on the AQ flash, this is what they gave me. I realize (now :rolleyes:) that it had nothing to do with the actual flash.

I was also told that there is no way to give me anything as far as paperwork regarding flashes because all they (you) do is hook up the Starscan tool and it does it's thing.

It's a little aggravating to not know what to look for as far as performance with my truck.

I'm still hearing that I seem to be the only person on the forums who has had it done.

No, I had it done this last Tuesday. It's to do with soot and EGR, DPF regens. They also did a trans reflash for hash shifting which has helped a lot, mileage did go uo alittle aswell.

AQ Flash Question

I brought my truck to the dealer for the second occurance of the 2262. I got the turbo tap and cleaning.

I asked the dealer to update the ecm to the latest 6235 1235 AQ flash for my '08 QC 4x4 6.7L Auto. After picking up my truck I noticed that it said the ECM had the latest update, but I know my truck only had the AP flash.

I called the dealer and asked why they weren't able to update to the AQ flash, after he checked with the mechanic he called me back and said the AQ flash was pulled and wasn't able to be installed.

He also said he had a truck that had the AQ flash in for service and since the AQ flash was removed from release they had to back level the truck to the AP flash which I didn't think they could do.

Does anyone have better information on the AQ flash?

Thank you to all who read and reply...

Bob

I can't understand why this AQ flash is so elusive to us all. Why can't the dealers tell us what the heck it's for? Makes no sense.

Because the dealers do not know. Chrysler does not provide much information on these updates. Sometimes if its part of a TSB the dealer may get a short comment but not all that informative.

I have had the AQ for a couple months, didn't notice any power or mpg difference. I also had the CCN update done, for the first time ever I saw the Trans Temp light turn on. At 2500 miles the tranny when out of my '08 Mega 6.7 and when I took it to the dealer they said I over heated it. I fought with them for three months until I finally gave up and put an after market trans. I just assumed that it didn't have a light or anything which seemed chicken , now with the CCN update I see the light...........makes you wonder if it was inop until now. Maybe they don't post what some of these updates are because they fix problems that where manufacturer errors?
