JCB K4718 Intake Manifold Pressure Drop too High at Cranking Repair

Posted by obd2tool 2012 on December 18, 2021 at 4:00 AM Comments comments (0)

Here is a document on how to repair JCB equipment K4718 trouble code intake manifold pressure drop too high at cranking.More repair case for JCB,please refer to:JCB Trouble Repair

JCB-K4718-Intake-Manifold-Pressure-Drop-too-High-at-Cranking-Repair

The measured intake manifold pressure (the signal from the boost pressure sensor) is below the warning limit during engine cranking.

Possible causes are:
The engine air supply is clogged.
The boost pressure sensor wiring is defective.
The boost pressure sensor is defective.

Reaction in EEM
The FC is stored and the warning lamp is activated. The CAN message indicates active fault.
NOTE:The engine may not start, or it starts slowly and runs poorly.

Solution
Check the engine air supply system completely, consult the service instructions if necessary.
Check the air filter.
Check the piping from the air filter to the turbocharger (look for obstacles in the joints, the bends).
Check the turbocharger.
Check the piping from the turbocharger to the charge air cooler (look for obstacles in the joints, the bends).
Check the charge air cooler.
Check the piping from the charge air cooler to the inlet manifold (look for obstacles in the joints, the bends).
To check the electrical defects, check the boost pressure sensor, the sensor wiring and the controller input: First save the error log and then erase it. Restart the ECU after erasing the error log. If the fault occurs again during the next driving cycle, check the following paths:
Check the boost pressure sensor wiring, the connectors and the contact surfaces of the connector pins (possible oxidation).
Check the operation with another boost pressure sensor to see if the boost pressure sensor is defective.

JCB Electronic Service Tool diagnostic interface is used for fast and effective fault finding, check maintenance standards, see if the machine has been abused, view and change machine set up data, flash ECUs with the correct data files. You can resetEMShours, edit speed limiters and use other functions what require special unlock.

JCB Service Master is a gateway application allowing a large number of Vehicle Support Applications to be linked using one familiar interface. The interface acts as a graphical tool for selecting the target vehicle from a groups of Vehicle Families and triggering the particular Service Tool Application desired. This removes the need for a user to ‘remember’ every individual service tool available and select which one if intended for a particular machine.

The JCB Service Master also provides several key features that will accompany all JCB projects, a Multi Language editing tool that provides a means of individual text string translation for all JCB Applications and a means to select a localised language translation for the each JCB Application.

#Purpose
Real Time Graphing monitors ECM data and displays it in graphical form as it occurs. When running Real Time Graphing for the first time, a set of parameters must be selected to graph.

#Accessing
1). Connect Cat ET to the service tool connector, and establish communication with the ECM.
2). To run the Real Time Graphing function, select Real Time Graphing from the Information menu.

3). The Real Time Graphing screen is displayed. The Select Graph Set dialog box is displayed the first time this tool is accessed.

Real-Time-Graphing-using-Caterpillar-ET-Software-3

If the Select Graph Set dialog box displays:
1). Click the New button to create a new set. The Maintain Graph Sets dialog box is displayed.
2). Select a set from the Select Graph Set list box. As a graph set is selected, the parameters for that set display in the Parameters list box.

→Using the up and down arrows on the keyboard, each set and its parameters can be viewed consecutively in the Select Graph Set dialog box. If a set is created, it can be selected by the first letter of its name.
→A maximum of six parameters may be selected.
→Click the Save As button. The Save Graph Set dialog box is displayed, then click Yes.
→Enter the graph set name in the Enter Graph Set Name text box.

#Screen Layout
The Real Time Graphing screen has the following areas:

ECM Title Area – The ECM title area displays the name of the selected graph set.
Error Status Text Box – The Error Status Text Box displays errors that occur while retrieving the parameter value. If more than one error occurs, the text box changes to a drop-down list for viewing all errors. “No Error Present” displays if there are no errors. “Unable to plot value” displays if the selected parameter cannot be plotted.
Legend Area – The Real Time Graphing legend area displays the selected parameters and is located above the graph. These parameters display with the corresponding line color. These colors cannot be changed. Parameters with an error will display an asterisk to indicate the parameter error is listed in the Error Status text box. The status parameter and its unit of value display on the y axis. These display on each side of the graph. These parameters display in the line color.
Graph Area – The Real Time Graphing area displays the time in seconds on the x axis (ten seconds is default) and the minimum and maximum values for each parameter on the y-axis. State parameters (for example, the only status is “On” or “Off”;), initially display with dashed lines until the graph begins to trace the state parameter’s value.
Buttons – The buttons available in the Real Time Graphing screen are:

a). Graph Sets

Real-Time-Graphing-using-Caterpillar-ET-Software-8

b). Settings

Real-Time-Graphing-using-Caterpillar-ET-Software-9

To change the graph settings:
1. Click the Settings… button. The Graph Settings dialog box is displayed.
2. Select the time, in seconds, from the X-Axis Range drop down list.
3. In the Y-Axis Range area, the status parameters are listed with their minimum and maximum default values. To limit the range, double click on the cell and enter a new value.
4. In the Options area, click the options to be displayed on the Real Time Graphing screen.
→Click Show Grid to display grid lines on the graph area.
→Click Show Symbols to display symbols on the graph lines corresponding to the symbol above the parameter.
