TSB 07-17-3 6.4L - PCM UPDATE - BUILT BEFORE 7/30/2007 - INTERMITTENT P0342 AND/OR P1336, UPDATE - PTO FUNCTION, TURBO PROTECTION, HIGH IDLE, SHIFT QUALITY AND IC

FORD: 2008 F-Super Duty

This article supersedes TSB 07-16-2 to update the Action required.

ISSUE:
Some 2008 F-Super Duty F-250-F-550 vehicles built before 7/30/2007 and equipped with the 6.4L engine may exhibit one or more of the following concerns:

• Intermittent P0342 or P1336 powertrain control module (PCM) reprogram prior to normal Powertrain Controls/Emissions Diagnosis (PC/ED) Diagnostics)

• Loss of stationary elevated idle control (SEIC) or battery charge protection (BCP) during power take-off (PTO) operation when body is rolled or wheels are rocked

• Turbocharger bearing failure due to very cold ambient temperatures, frozen turbocharger actuator with diagnostic trouble code (DTC) P132B at temperatures below freezing

• Unacceptable engine idle RPM ramp rate at cold engine temperatures/cold ambient conditions in Neutral/Park with foot off Brake/Clutch

• Unacceptable engine idle RPM ramp rate during diesel particulate filter (DPF) regeneration in Neutral/Park with foot off Brake/Clutch

• Transmission upshift quality, engagement duration or feel, and shift busyness or powertrain hunting

This calibration update also includes diagnostic and malfunction indicator lamp (MIL) operation improvements for P200E, P242D and P2033. Follow normal PC/ED diagnostics for symptom or DTC identification.

This calibration also includes instrument cluster (IC) message centre updates for distance to empty (DTE) reads in reverse on dual fuel tank applications, "Engine Warming" turbo protection and "Stop Safely Now" exhaust over temperature warnings.

ACTION:
Reprogram the PCM, Transmission Control Module (TCM), and IC (Reprogram the IC by selecting Module Reprogramming, IC) to the latest calibration using IDS release 50.7 patch 10. When reprogramming the PCM on automatic transmission equipped vehicles the TCM will also automatically be reprogrammed to the latest level. This new calibration is not included in the VCM 2007.7 DVD.

Please print/copy the Customer Information Sheet attached to this Technical Service Bulletin (TSB) and insert it into the glove box Owners Guide for future customer reference.

WARRANTY STATUS:
Eligible Under Provisions Of New Vehicle Limited Warranty Coverage And Emissions Warranty Coverage
IMPORTANT: Warranty coverage limits/policies are not altered by a TSB. Warranty coverage limits are determined by the identified causal part.

 

Glad Ford worked out all of the bugs on this new 6.4. LOL



I kinda am getting the idea that you 6.4 owners are the guinea pigs?

 

I don't feel like that at all. I got my truck 1st week of February 07. almost 8000 miles on it and no problems. Runs just as good as my 06 PSD. My F450 is a great truck.

 

Do you think they fixed all these problems on the JOb 2 Trucks?

 

my truck was built before 7/30...it runs "ok" in my opinion...should i take it in and get it reprogramed just for the heck of it??

 

Same question as FordStoker. . . .is this a "must have" update? My 08 F250 SD 6.4 seems to be doing fine.

 

No, this is not a "must have" update, it is a TSB and not a recall. If your truck is having one of the problems listed in the TSB, take it in. If not, keep enjoying your truck.

 

If you take it in "just for the heck of it" (with none of the listed problems in the TSB), do not be too suprised if the dealer does not want to reflash it or will reflash it at "your" expense.

 

The only complaint I have about the trucks I have driven is the transmission upshift quality. Seems like the truck quits running then shifts, its just not smooth at all.

 

how can i tell the build date? engine or truck

 

On the tag on your b pillar is the build date.

Where your tire pressure, ser.number, axle, etc... is

 

just picked up my 2008 from dealer this afternoon having a cool service manager is the way to go. i had mention of this tsb couple a weeks ago well to day i went for first oil change and he updated my truck. he did mention that he wrote on paper work that he wrote that i had rough shifting otherwise he would not been able to justify. Also bad news for another SD driver, with only 2000 miles this guy ended with bad fuel pump. i asked service manager and had no problem if i took pictures when cab is removed sometime next week. keep yall posted!

 

can you tell any difference since they updated it? does the truck run any better or anything??

 

Just had mine reflashed today. The shift quality is better....I think..although it wasnt that bad to begin with. It wasnt until I read the tsb that I thought I had shift problems.

.. but also included in the reflash is some upgrades that include more messaes on the message center. ie. Truck is Warming and Stop asap (or something to that effect in case of a problem.

 

only drove for 2 miles back home will get out and drive tomorrow and see if i notice any difference.
