How to Install the Engine Accelerator for HINO L-Series Truck

Outline figure of Engine Accelerator

How to install
• Ensure that the body control lever is equipped with a full speed stopper, in order to control the stroke of the sensor lever.
• Adjust the body control lever so that the full speed stopper makes contact earlier than the stroke stopper of accelerator sensor.
• Ensure that the accelerator sensor lever will be in contact with the idling stopper by adjusting the speed control lever when the P.T.O. or equipment is not operating (during normal driving).

[NOTE]
The clearance specified for the accelerator sensor stroke stopper is for reference only.
If the sensor side stopper comes into contact earlier, stresses will be imposed upon the sensor shaft and may result in damage to the parts.
Also, if the sensor lever does not come into contact with the idling stopper, it may result in improper engine operation during normal driving conditions.

When installing the cable on the accelerator sensor lever, ensure that the cable pulls in a parallel direction to the lever stroke so that an imbalanced load is not applied to the sensor shaft. See the following figure.

Cautions when installing the engine accelerator sensor
• Do not attempt to disassemble the sensor.
• Do not drop or otherwise shock the sensor, as this will lead to malfunction.
• Prevent water intrusion or direct splash.
• The sensor operating range is -30°C to 80°C (-22°F to 176°F) and should only be used in that range.
• Avoid mounting the sensor in an area that may receive casual impacts.
• The sensor must be located in an area free of oil, dust, humidity, chemicals and vibration.
• If a well protected location is not available, then a cover must be installed.
• Install the wiring harness so that it is secure and not able to twist or bend.
• Refer to the Chapter 7 for instructions regarding installation of the harness.
• If the sub-harness is not long enough, extending the harness must be completed using the same type of wire.

hex. bolts.
9.Bolt down the hydraulic cylinder to the supporting arm using the M 8 x 65 and M 12 x 25 hex. Bolts and the eccentric bolts. Assemble the eccentric bolt so that there is still some free movement.

10.Adjusting the hydraulic cylinder:
– Press the drive motor down into the gear.
– Pull out the ram.
– Set and lock setting screw (S) so there is 0.5 mm of play
(1/4 turns) up to the stop.
11Install the cutterbar drive belt (P) and adjust it
– see page 7.2.2, Installing and adjusting the cutterbar drive belt (1) (Cutterbar drive without variable-speed drive) and/or Installing and adjusting the cutterbar drive belt (2) (Cutterbar drive with variable-speed drive).
12Install the left-hand guard and the universal coupling.

Deutz TIRE4 Engine SCR Service Routines by SerDia2010

1 Pressure test
While pressure test with a stopped engine the DEF pump is regulated at 9 bar. The test is
used to check the pump components to their function. The test involves no automatic
evaluation and must be actively terminated. It is to verify that the system controls on 9 bar
and this pressure is retain.

2023 Deutz Serdia2010

Deutz Diagnostic Kit

2 Injection Test
At the start of injection testing first the DEF pressure is built up. Then a definite amount
DEF is injected. The test is used to check both, the pump module and the function of the
dosing module.
The dosing module must be removed for this test.

3 The service “empty lines” must be accomplished after a service routine is completed, that the DEF lines can be emptied after ignition change.
(This is not necessary for the EOL-test or the service regeneration)

SCR-Heater relay activate
Setting of the individual heating relay to check the customer’s wiring.
– DEF Heater Main-relay
– DEF Heater Suction line
– DEF Heater Pressure line
– DEF Heater Back flow
– electrical heater – Supply Modul
– tank heater relays (coolant water)

After changing the SCR Catalyst the service “SCR Cat changed” must be set.

inducement counter reset
The exhaust legislature requires that emission-related defects, provided they bear a
permanently,enable a power reduction.
Current derating must be reset after repairing/troubleshooting by the service tool.
The button appears only in Serdia2010 when the power reduction is active.
After the counter has been reset, the button disappears.

Preparations:

Scania SDP3 2.60.1 Truck Diagnostic Software

Scania Multi EPC 2024.03

Scania VCI3 High quality

Wake-up signal for Scania Communicator, short circuit

Error identification

Wake-up signal for Scania Communicator is short-circuited to ground.

Cause

Fault in harness-to-component connectors or cable harness for the wake-up signal for Scania Communicator.

Internal fault in ALM control unit E7.

Notes

–

Symptom

The alarm system cannot initiate Scania Communicator.

Action

Disconnect the harness-to-component connector to ALM control unit pin A5.

Measure for short circuits throughout the cable harness.

If there are a number of harness-to-component connectors between the wake-up signal and the ALM control unit, disconnect them and measure in order to isolate the fault.

If the fault is not in the cable harness it is probably an internal fault in ALM control unit E7.

HINO J05E Engine 2018 VNT Actuator Initialize Error P003A Solution

This instruction show you guide on how to solve HINO J05E Engine 2018 VNT Actuator Initialize failure.

Related Contents:

HINO DX3 Diagnostic Software

NEXIQ USB LINK2

Technical Description:

1) The VNT actuator moves the nozzle vane steplessly by the LEA (Linear Electric Actuator) to control the turbo speed and boost pressure.

2) The LEA has a sensor to detect the movement of the actuator, always monitoring the reading and actual value of the nozzle vane opening.

3) Wiping operation is performed while the engine is stopped for the purpose of removing soot and oil coming out from the range of vane operation and checking the turbo mechanical operating range for abnormality.

DTC Set Condition:

1) DTC Detection Condition:

a) Starter key “ON”.
b) The battery voltage is in the range of 10 to 16 V.
c) The engine is stopped, or the engine speed remains at 500 r/min or more for 5 seconds or more.

2) Judgement Criteria:

a) Initialization failure – When the amount of operation after power has been turned ON is larger than HI range, or when the Hall IC output does not become constant after 5 seconds has elapsed

Reset Condition:

1) After normal operation is restored and the starter key is turned “LOCK”.

Indication, Warning or System Control Regulation When The DTC Is Set:

1) MIL: ON

2) SVS light: OFF

3) Engine output is restricted.

Symptoms On The Vehicle The DTC Is Set:

1) Symptoms On The Vehicle Due To Backup Control (Fail Safe Function):

a) Engine output is insufficient.

2) Symptoms On The Vehicle Due To Malfunction:

a) None

Pre-Inspection Work:

1) Check that the battery voltage is in the normal range.

After-Inspection Work:

1) Clear all past DTCs.

2) Check that no DTC is detected after test drive.

Possible Causes:

1) VNT link is stuck or cannot operate due to rust, etc.

2) External link is disconnected.
