Service Bulletin/Repair Instructions
After connecting to a truck using DX3, it may be necessary to review or create a DX Diagnostic Report for review.
Vehicle report
Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.

The engine ECU (Engine Control Unit) on all 2016MY-2018MY trucks contained in dealer inventory need to be reprogrammed prior to delivery. Subject vehicles contain an error in the DEF monitoring program. To eliminate this situation, it is necessary to reprogram the engine ECU with improved software prior to sale of the vehicle.

SCB-001-16 A subject vehicle may exhibit an illuminated check engine lamp with DTC (Diagnostic Trouble Code) P14BF ?EGR (Exhaust Gas Recirculation) Valve Controller Temperature Sensor 1, 2 Rationality. The EGR valve may falsely detect this rationality fault, causing the P14BF DTC to be set and stored in the engine ECU. Enhanced EGR valve software is available to prevent this false detection.

SB-16-019 An enhanced fuel cut valve is available to address a potential sticking condition that results in excess residual pressure in the dosing injector (7thinjector) supply pipe. A sticking fuel cut valve may result in the following DTC?s (diagnostic trouble codes) setting: 1. If DTC P0005 (fuel cut valve stuck closed) sets in the engine ECU, replace the fuel cut valve with the part number listed below. 2. If DTC P20DE (pressure sensor performance invalid) or DTC P20DF (pressure sensor signal too low) set in the engine ECU, this could be a result of the fuel cut valve sticking. Follow the workshop manual diagnostic procedure in section 4 of the Hino Workshop Manual (J08E Engine Control System) for the DTC. Also, inspect for signs of fuel contamination that could restrict the fuel filter or bubble separator filter. If no issues are identified with fuel contamination, and the workshop manual procedure does not identify a concern, replace the fuel cut valve with the part number listed below.

SB-16-015 Enhanced DCU (Dosing Control Unit) software has been released.Illumination of the check engine light. The DCU may falsely detect an issue and record any of the 3 following DTC?s in the DCU. P142A(DEF pump temperature sensor - Out of range) P204B(DEF pressure sensor ? Rationality) P20A1(Reverting valve for DEF pump stuck close) In rare cases, the completion of the after-run process might be mistakenly aborted. This occurs when the ignition key is cycled back on and then off prior to after-run completion. If this occurs when ambient temperatures are below freezing and the urea is allowed to fully freeze, internal damage to the DEF pump may occur. Once damaged, urea could migrate into the DEF pump electrical connector and SCR harness resulting in corrosion. This corrosion could result in detection of any combination of SCR(Selective Catalyst Reductant) DTC?s including but not limited to: P142A(DEF pump temperature sensor - Out of range) P208A(DEF pump motor circuit - Open load) P208B(DEF pump motor - Functional) The enhanced DCU software prevents the after-run process from being aborted prior to completion.

SB-16-006 Some vehicles built before January 2016 and equipped with a leaf spring rear suspension may experience a dislodged or missing spring pad. As an enhancement, the rear axle leaf spring hanger design has been changed to eliminate the spring pad. In the event that one or more spring pads have become dislodged or found missing, all four rear axle leaf spring hangers should be replaced with the enhanced design hangers.

SB-16-004 1. In the event that a subject vehicle exhibits an illuminated check engine lamp and DTC?s P2201, P2214, P206B, P207F, or P20EE are stored in the DCU, the NOX sensor may have failed due to a cracked NOX sensor heating element. Follow the revised Workshop Manual diagnostic procedure to determine if the NOX sensor has failed. 2. Enhanced DCU software is available to prevent the NOX sensor heating element from cracking due to exposure of condensation on the heating element. 3. The enhanced DCU software will also prevent false detections of DTC P142A being set in the DCU.

SB-15-031 Foreign debris in the DEF (Diesel Exhaust Fluid) tank may cause the SCR (Selective Catalyst Reduction) system to malfunction. This can result in DTC?s (Diagnostic Trouble Codes) P20E8 or P20E9 - DEF Pressure Abnormality. An inlet strainer for the DEF tank has been made available to prevent foreign material from entering the DEF tank.

AA0Q0 A subject vehicle may exhibit an illuminated check engine lamp with DTC (Diagnostic Trouble Code) P2148/P2151 (Malfunction of injector solenoid valve drive system common ½, B+ circuit). The engine ECU may falsely detect an issue and record these DTC?s in the engine ECU. Enhanced ECU software is available.

TT-15-016 The purpose of this publication is to communicate the standard measuring positions on the Hino chassis. In some cases, the customer may report a visual chassis posture concern where the chassis appears to be leaning more towards the driver side or passenger side. The following publication can be referenced to obtain the manufacture?s measurement positions and specifications. Should the truck not meet the specifications, you should consider the following potential causes noted in the inspection guideline section below.
