SERVICE INFORMATION BULLETIN
Subject:
Supply Pump Suction Control Valve Design Change – J05D Engines
Supersedes SB-07-006 dated 04-07-2008
(Revised 2-24-2009 to include 2010 model year vehicles)

This bulletin provides diagnostic information for monitoring the engine running data to
determine if the Suction Control Valve is defective, and a service procedure for
replacing the Suction Control Valve when necessary. The SCV should be tested and
replaced when necessary before replacing the supply pump assembly for a fuel
pressure related concern.

1. RELEVENT MODELS
2005-2010 NA6J (145), NB6J (165) and NC6J (185) Conventional Cab all Models
equipped with a J05D engine.

2. CONTENTS
2005-2010 model year vehicles may exhibit a low or fluctuating idle, low power
complaint, or a Final Pump current value that is higher or lower than expected. In
the past it was necessary to replace the supply pump to correct an incorrect pump
current value reading. Hino has released the Suction Control Valve as a service
part and in the following will provide a service procedure for diagnoses and
replacement of the SCV.

SERVICE INFORMATION BULLETIN
DIAGNOSES:
1) Allow the engine to reach normal operating temperature. ( 70º C or 158ºF )
2) With engine at base idle and all extra loads turned off such as A/C, PTO, etc., monitor the
“ Final value of pump current target “ using Diagnostic eXplorer
3) Monitor the “Final value of pump current target “ for 30 seconds.

4) Record the Maximum and Minimum values reached during the 30 second time frame
- Take note of the average current value.
- Calculate the maximum current variation value. Maximum variation is calculated by
subtracting the Minimum value from the Maximum value
- Reference the table below

- Average pump current values are within expected range
- Total Variation is less than 120 for J05D - TA engines and less than 160 for J05D - TF
engines.
SCV NO GOOD
- Average pump current target is less than or greater than expected average
- Total Variation is greater than 120 for J05D - TA engines and greater than 160 for J05D –
TF engines.
5) Continue to service procedure if the SCV was found to be No Good during diagnoses.

SERVICE PROCEDURE:

1) Disconnect the SCV connector.
Do not use excessive force when
disconnecting or connector damage will
result.

2) Clean the SCV and mounting area.
Be sure to keep the area around the
SCV clean to prevent dirt or foreign
material from sticking to the pump
housing or installation surface.

3) Remove the two SCV mounting bolts.

7) Install new O-ring into the pump
housing. Make sure the O-ring
groove is free from dirt and debris.

8) Apply a light coat of fresh oil to the
small O-ring to ease installation, and
to prevent O-ring damage.

9) Insert the SCV into the pump housing
by gently rotating right and left until
the SCV is flush with the pump
housing.
