Other system enhancements and improvements:
A. Stationary DeSoot is now available with this software. A separate
Service Bulletin will address specific procedures for Stationary DeSoot.
B. Enhanced P2262 diagnostic strategy will no longer set this DTC for conditions where there are no adverse affects.
C. New Scan Tool enabled P2262 Fault Diagnosis test (Used Before
Repair) with anew functional test of the turbocharger. As before, this
test determines the correct repair direction when DTC P2262 is present.
Refer to TSB 09-002-09 Rev A (or laterbulletin) for detail on using
this test to diagnose and repair P2262 concerns.
D. New DTC P226B - Turbocharger Boost Pressure Too High - Mechanical - indicates
incorrect airflow and can be caused by the turbocharger, which should be cleaned if
it is the cause for this DTC. This DTC can also be caused by other air handling
system components. Refer to DTC-Based Diagnostics to properly diagnose and
resolve this concern.
E. New DTC added for P2563 - Turbocharger Boost Control Position Sensor
Performance. This DTC indicates diminished variable geometry turbocharger travel,
which is resolved by cleaning the turbocharger. Diagnosis and repair procedures for
the DTC have been published in DTC-Based Diagnostics in TechConnect.
Using a Scan Tool with the appropriate Diagnostic Procedures available in
TechCONNECT, verify all engine systems are functioning as designed. If DTC's are
present other then the ones listed above record them on the repair order and repair as
necessary before proceeding further with this bulletin. If any of the above conditions/DTC's
are present, perform the Repair Procedure.
NOTE: This calibration addresses certain conditions for each of the faults listed, but
does not correct a mechanical failure.
NOTE: All other DTC's or symptoms MUST be addressed prior to returning the
vehicle to the customer.
Qty. Part No. Description
1 04275086AB Label, Authorized Modification
NOTE: If this flash process is interrupted/aborted, the flash should be restarted.
NOTE: Stationary DeSoot will not perform without a P1451 DTC. Updating the ECM
will automatically clear the P1451 DTC from the ECM's memory. If the soot
threshold is great enough where a Stationary DeSoot is required, it may be
necessary to drive the vehicle so that the P1451 DTC will reset.
1. Does this vehicle have a P2262 DTC either active or stored?
a. Yes >>> Refer to TSB 09-002-09 REV. A (or later bulletin) before proceeding with
b. No >>> Proceed to Step #2.
2. If this vehicle is a 2007, verify Recall G30 has been properly performed. Bootloader
Software will be displayed on the Scan Tool as up-datable. If the recall has been
properly performed, updating Bootloader is NOT required, (even though the calibration
may be displayed as up-datable).
3. Reprogram the ECM with the latest software. Follow the detailed service procedures
available in DealerCONNECT/TechCONNECT, Refer To Group 8 - Electrical > 8E -
Electronic Control Modules >MODULE, Engine Control, Diesel > Service Information >
Standard Procedure > PCM/ECM Programming - DIESEL. After PCM
reprogramming, the following must be performed:
a. Clear any DTC's that may have been set in other modules due to reprogramming.
The wiTECH application will automatically present all DTC's after the flash and
allow the tech to clear them.
4. Type the necessary information on the "Authorized Modification Label" and attach it
near the VECI label.
Reimbursable within the provisions of the warranty.
Just before purchasing my 2008 Dodge Ram 2500 (i6 6.7L Turbo Diesel), I took it to Larry H. Miller Dodge in Sandy. I saw a few dents on the lower suspension and wanted to determine if there were other issues before committing to a purchase.
At the time, they quoted about $1200 in repairs for all four ball joints (upper / lower, left and right side), and outer tie rod ends. Considering the deal I was getting on the truck ($24000), I thought $1200 in front-end work would still be a bargain.
The odd thing was, the front tires showed no signs of wear, the ride was fine (until about 75mph, where it would shake a bit) and there was no obvious indication of front-end problems.
On Monday (at 7am), I dropped the truck back off at Larry H. Miller to effect the repair work. Around 2pm, LHM phoned me (Service advisor = Jim) and indicated that the price was now up to $2500 and pretty much the entire front-end needed to be replaced (shocks, control arms, ball joints, tie rod ends, etc..). I said, No-Thanks and recovered my truck.
Yesterday, I decided to get a second opinion and took the truck to Les Schwab Tire & Service Center (Taylorsville). After 10 minutes of inspecting, the two mechanics walked me over to the truck, showed me how they inspected and indicated that no front-end work was needed. They said, there was a little play in the ball joints, but that was normal for stock Dodge parts.
Now that the founder is dead (Larry H. Miller), are they becoming so desperate for revenue that they would lie to generate short-term gains in service fees by losing a customer for life (long-term)?
