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 32°F) 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 HOS 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 HOS 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. Check that the MVCI indicates the applicable program ID listed below (or a later program ID) as the Available Update when the update begins. 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 should not assume this bulletin applies to your vehicle, or that your vehicle has the condition described.

What is the outside temperature when the vibration occurs? Above 32 °F 2. Below 32 °F At what speed does the vibration occur? Low speed (up to 30 MPH) 3. Temperature has no effect on vibration Medium speed (30-65 MPH) High speed (above 65 MPH) 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 HOS 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.

I YI - Y - N II Page 4 of 8 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 °F 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. ~ Apropeller purple mark here indicates the shaft has already been replaced. Page 5 of 8 3. Remove the propeller shaft protector.
