5. Handling of Dealership Inventory
Under 40 Code of Federal Regulations §1068.101, a dealer cannot sell, offer for sale, or introduce or deliver for introduction in interstate commerce a new motor vehicle when it is aware that the vehicle does not comply with an applicable Federal Motor Vehicle Safety Standard or contains a defect related to motor vehicle safety. A civil penalty of up to $44,539 may be assessed for each engine or piece of equipment in violation. In addition, 49 Code of Federal Regulations §577.13 requires us to provide the following advisory: It is a violation of
Federal law for a dealer to deliver a new motor vehicle or any new or used item of motor vehicle equipment (including a tire) covered by this notification under a sale or lease until the defect or noncompliance is remedied.
We request your assistance to ensure involved vehicles are identified and not delivered prior to performing the remedy.
OVERVIEW:
Software updates are required for the Engine ECU (Engine Control Unit) and DCU (Dosing Control Unit) modules. These updates are intended to address the following items.
1) SCR (Selective Catalytic Reduction) Feed Back Monitor (P2BAE)
2) DPF (Diesel Particulate Filter) Feed Back Monitor (P24A1 or P24A0)
3) Urea SCR Tank Heater Valve Stuck Open Monitor (P20B2)
4) MIL (Malfunction Indicator Lamp) ON software issue for
DCU; OBD (On Board Diagnostics) Improvement
5) NOx (Oxides of Nitrogen) sensor offset monitor
(P2201)
Hino is using this opportunity to implement OBD improvement items (which are not by themselves recall items) that are included in all affected engines.
<Additional Items>
DPF Over Temperature Monitor (P200C)
All Cylinder Misfire Detection Monitor (P0300)
Misfire Monitor (Conventional vehicles: P0301-P0304)
DOC1 (Diesel Oxidation Catalyst) Over Temperature Monitor (P2428)
SCR Feed Back Monitor (P2BAE)
Reductant Temperature “Too High” Monitor (P24FF)

DCU & ECU REPROGRAMMING PROCEDURE
CAUTION: Two modules will be reprogrammed during this procedure. A battery charger MUSTbe installed on the vehicle to ensure battery power does not go low during reprogramming or damage to these modules may occur. DO NOTstart the procedure without the battery charger being installed.
1.Prepare a DXII compatible interface, such as the Denso DST-ior the NexiqUSB Link 2 to perform this reprogramming procedure.
To assemble the interface cable, perform the following steps.
(1) Connect the DLC (Diagnostic Link Connector) cable to the interface.
(2) Connect the USB Cable to the interface.
(3) Connect the USB connector to the USB port on your computer.
2.Connect the DLC cable to the vehicle’s DLC connector. The DLC connector is found under the dash on the left side of the steering column.
3.On your computer, locate the “Hino DX2” icon and open it.
4.Hino DX2 will prompt you for a “User ID” and “Password”. Enter your User ID-, and password and then select the “Login” icon. Verify that the DX2 has software version 1.1.19.6 or later.
