REVISION SUMMARY

Under WARRANTY CLAIM INFORMATION, a failed part number (FPN) was changed.

 

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

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.

 

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.

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.

i-HDS Diagnostic Software and J2534 Reprogramming Software

American Honda Motor Co., Inc. ("Honda") offers the i-HDS (Honda Diagnostic System) software suite for the diagnosis and repair of electronic systems on Honda and Acura automobiles, and for the reprogramming of electronic control units (including, but not limited to, ECMs and PCMs). This software provides access to all Honda and Acura vehicle systems (access to the immobilizer security system requires a Security Professional level software subscription and Vehicle Security Professional [VSP] registration with NASTF). To use the i-HDS software, you need to purchase one of our convenient subscription options. In addition, you will need a pass-thru Vehicle Communication Device (VCI) that is compliant with SAE J2534-1 and J2534-2 in order to communicate with the vehicle

 

Vehicle Communication Interfaces (VCI)

The i-HDS software supports the use of a generic pass-thru VCI that is compliant with SAE J2534-1 and J2534-2. However, Honda recommends the Denso DST-i or the Bosch MVCI for use on Honda and Acura vehicles, as Honda has worked closely with these manufacturers to ensure their hardware and our software interact safely and within the J2534-1 and -2 specifications, for both diagnostics and reprogramming. If you choose to use a generic VCI, please carefully consider the customer and technical support options you will receive from your chosen device supplier. Honda does not provide technical or customer support for generic VCI devices.

The VCI Application Table below lists devices that either are approved and supported by Honda or are known to have completed and passed an independent, exhaustive validation program with our i-HDS software suite.

VCI Name	Manufacturer	Version Information		Notes
		Firmware	J2534 API

* These versions may have been superseded. Honda provides the latest supported versions to current i-HDS subscribers.
** Version used in validation program. See Terms and Conditions and Important Notice Regarding Reprogramming below for more details.

 

Reprogramming with the J2534 Rewrite Application in i-HDS

Included in the i-HDS software suite is a new reprogramming application called J2534 Rewrite. This application is made available to all subscribers of the i-HDS software suite and replaces the previous generation software, J2534 Honda Pass-thru Reprogramming Software.

This new application is compatible with generic VCIs that comply with SAE J2534. It must be used to reprogram any Honda/Acura vehicle equipped with ECUs that support reprogramming. Refer to the table below for legacy applicability for the programming of ECMs and PCMs. Though system dependent, late-model vehicles may be equipped with other ECUs that support reprogramming as well, e.g. ABS or VSA. J2534 Rewrite must be used to reprogram these control modules, as instructed in an applicable service bulletin.

As shown in this table, not all legacy Honda/Acura models are equipped with a reprogrammable ECM/PCM. Furthermore, all 2007 and later models not listed in the table are fully supported with this application.
