REVISION SUMMARY
• Under AFFECTED VEHICLES, vehicles with Continental PCMs were added.
• Under SOFTWARE INFORMATION, Continental PCMs were added.
• Under INSPECTION PROCEDURE, the HDS OBS data list parameters were changed, and HDS parameters were
updated to show a PGM-FI snapshot.
SYMPTOM
Under certain driving conditions, there is excessive vibration between 30 and 65 mph.
POSSIBLE CAUSES
For 2WD and 4WD vehicles, the calibration VCM operation combined with the action of the lock up torque converter
creates excessive vibration.
Additionally for 4WD vehicles, the propeller shaft’s center support bearing bushing material may not effectively dampen
vibrations in cold (below 32ºF) temperatures.
CORRECTIVE ACTION
Do the inspection procedure, and based on your results, you may need to update the PCM. For 4WD vehicles, you may
also need to replace the propeller shaft.
SOFTWARE INFORMATION
NOTE: Unnecessary or incorrect repairs resulting from a failure to update the HDS or MVCI are not covered under
warranty.
MVCI Control Module (CM) Update:
Application Version 3.001.040 or later
Database update 17-March-2015 or later
HDS Software Version:
3.016.018 or later
Before beginning the repair, make sure that both the HDS and MVCI are updated as listed above.
Do only the update listed in this service bulletin.
CUSTOMER INFORMATION: The information in this bulletin is intended for use only by skilled technicians who have the proper tools,
equipment, and training to correctly and safely maintain your vehicle. These procedures should not be attempted by “do-it-yourselfers,” and you

INSPECTION PROCEDURE
Customer Questions
Have the service advisor ask the customer the following questions:
1. What is the outside temperature when the vibration occurs?
Above 32 ºF
Below 32 ºF
Temperature has no effect on vibration
2. At what speed does the vibration occur?
Low speed (up to 30 MPH)
Medium speed (30-65 MPH)
High speed (above 65 MPH)
3. Under what driving condition is the vibration occurring?
Light or steady throttle
Hard Acceleration
Light braking
Moderate or hard braking
Test-Drive the vehicle
1. Test-drive the vehicle and confirm the customer information using the HDS; set the cruise control Cancel button in
the perimeter setting to trigger the snapshot. Then, set up the HDS to take a PGM-FI snapshot 15 seconds before
and after the trigger.
2. Drive the vehicle in the speed range where the customer feels the vibration. Once you feel the vibration, keep the
throttle and speed steady and press the cruise control Cancel button once to trigger the snapshot.
3. Save the snapshot.
4. Repeat steps 1 through 3 a second time before going to step 5.
5. Continue driving to create the vibration again. Once you feel the vibration, press the cruise control Cancel button
again to trigger the snapshot, then lift off the throttle for 2 seconds, and then resume the throttle.
•
•
If the vibration does not go away, this bulletin does not apply. Continue with normal troubleshooting.
If the vibration goes away, continue to Results.
Results
To review the snap shots, select the following signals:
• VPS Status
• Engine Speed
• M Shaft SPD
• Vehicle Speed
Set the cylinder (scale to 10).
NOTE: Setting the scaling parameters to the lowest levels will make interpreting the data easier.
This bulletin does not apply if any of the following occurred; continue with normal troubleshooting:
• The customer indicated the vibration occurred under braking or hard acceleration.
• The engine is not in valve pause when the vibration occurs.
• The snapshots 1 and 2 indicate fluctuations in the main shaft but the engine speed is steady – review the job
aid Torque Converter Clutch Shudder and Vibration.
REVISED IMAGES

Do REPAIR PROCEDURE A (2WD) if:
• The vibration occurred between 30 and 65 mph; review the snapshots 1 and 2 to see if the snapshot shows the
engine in valve pause and the main shaft and rpms are steady at the time of the vibration. Also check snapshot
3 to confirm that the engine was in valve pause once the vibration occurred and went away when you released
the throttle.
• The vibration occurred between 30 and 65 mph; the vibration occurred during light or constant throttle.
Do REPAIR PROCEDURE B (4WD) if:
• The vibration occurred between 30 and 65 mph; review the snapshots 1 and 2 to see if the snapshot shows the
engine in valve pause and the main shaft and rpms are steady at the time of the vibration. Also check snapshot
3 to confirm that the engine was in valve pause once the vibration occurred and went away when you released
the throttle.
• The vibration occurred between 30 and 65 mph; the vibration occurred during light or constant throttle.
Do REPAIR PROCEDURE C (4WD) if:
• The customer indicated that the vibration occurs when the temperature was 32 ºF or colder, you will need to
replace the propeller shaft.
REPAIR PROCEDURE A (2WD)
Update the PGM-FI and the A/T software. Refer to Service Bulletin 01-023, Updating Control Units/Modules.
REPAIR PROCEDURE B (4WD)
Update the PGM-FI or the A/T software. Refer to Service Bulletin 01-023, Updating Control Units/Modules.
• If your inspection results indicated to replace the propeller shaft, go to REPAIR PROCEDURE C.
• If your inspection results did not indicate replacing the propeller shaft, the vehicle is repaired.
REPAIR PROCEDURE C (4WD)
NOTE: Make sure you update the A/T and PGM-FI software or check that the software has been updated before
replacing the propeller shaft.
1. Raise and support the vehicle.
2. Check that the propeller shaft has not already been replaced. Check if there is a purple mark on the center support
bearing as shown below.
•
•
If there is a purple mark on the center support bearing, the propeller shaft has already been replaced with a new
part. Do not replace the propeller shaft again. If there is still a vibration, this bulletin does not apply. Continue
with normal troubleshooting.
If there is no purple mark, go to step 3.

3. Remove the propeller shaft protector.
4. Remove the flange bolts from the transfer companion flange.
5. Remove the flange bolts from the rear differential flange.

6. Remove the center support bearing mounting bolts.
7. Install the new propeller shaft by aligning the factory reference marks on the No. 2 propeller shaft to the rear
differential companion flange as shown below. Then install new flange bolts and torque them to 72 N·m (53 lb-ft).

8. Install the new center support bearing mounting bolts and torque them to 39 N·m (29 lb-ft).
9. Set the No. 1 propeller shaft to the transfer companion flange. Then install new flange bolts and torque them to
72 N·m (53 lb-ft).
10. Reinstall the propeller shaft protector.
