Resent so many friends when they use the CAT Caterpillar ET, showed the software is with Virus.whats problem about that?

In fact, the CAT caterpillar ET Software is safety, without any virus. But some friends asked us when they use the software ,why did show the software is with virus and that is not safe?
As you know, all the auto diagnostic tool software,when you use them, if you did not turn off or remove the Anti-virus software on your laptop, because the Anti-virus did not meet the software,so default the software is virus. So why when we install and activate the software,we need turn off or remove the Anti-virus software from the laptop.then can use.

So when you use the auto diagnostic tool software,if you do not want to remove the Anti-virus software from laptop.please turn off it that is best.

Programming Engine Cooling Fan for On-Highway Trucks (Caterpillar Engines)

Engine Cooling Fan

(A). Accessing the Configuration on CAT ET Software – Input Selections and Output Selections:
1). Fan Control Type
The Fan Control Type parameter determines if the ECM is used to operate the Engine Cooling Fan, this parameter must be programmed to “On/Off”, to “Three-Speed Fan”, or to “Variable Speed Fan Option S”. This parameter must be programmed to “None” if the ECM is not operating the Cooling Fan relay or the Cooling Fan Solenoid.

#Alternatives:
→None
→On/Off PWM
→On/Off DC
→Three-Speed Fan PWM
→Three-Speed Fan DC
→Variable Speed Fan Option S

#Advantages:
When the Engine ECM controls the Engine Cooling Fan, there is no need for second set of Coolant Temperature Sensors. Engine ECM fan control also provides additional features, such as Fan with Engine Retarder in High Mode.

2). Fan Override Switch
The Fan Override Switch parameter is programmed to identify the Fan Override Switch connection to the ECM. This parameter can be programmed to one of the available hard-wired options or J1939 data-link source inputs. The switch itself allows the Operator to turn on the Cooling Fan at any time, resulting in improved retarding/braking and Engine cooling.

#Alternatives:
→None
→J1/P1:7 (Input 4)
→J1/P1:47 (Input 5)
→J1/P1:6 (Input 6)
→J1/P1:46 (Input 7)
→J1939 – Body Controller
→J1939 – Cab Controller
→J1939 – Instrument Cluster

#Advantages:
When programmed to one of the input Alternatives, this parameter allows the use of the Fan Override Switch, which results in improved Engine retarding/braking and Engine cooling.

This instruction show you guide on how to repair Perkins 1106D electric power generation (EPG) cranks but will not start with high press fuel system trouble.

Preparations:
Newest Perkins EST 2022A & 2019A Full Support Free Download

Procedures:
1.Use the Perkins electronic service tool to check the absolute fuel rail pressure while the engine is cranking at a minimum speed of 150 rpm.
2.If the absolute fuel rail pressure is less than 25 MPa (3625 psi), perform the following
procedure:
a.Check that the inlet pressure at the fuel rail pump is greater than 50 kPa (7.25 psi). If the inlet pressure is less than 50 kPa (7.25 psi),repeat the diagnostic process from “Low Pressure Fuel System”.
b.Check for fuel leaks in the high pressure fuel system. Rectify any fuel leaks and then recheck the pressure in the fuel rail. If the fuel rail pressure is greater than 25 MPa (3625 psi),proceed to test step 3.
c.Use the electronic service tool to perform a solenoid test on the fuel rail pump. Refer to Troubleshooting, “Fuel Rail Pump Solenoid -Test”.
d.If any service has been performed as a result of Step 2.c, attempt to start the engine. If the engine will not start, repeat the diagnostic process from “Diagnostic Codes”.
e.Check the pressure relief valve in the fuel rail for leakage. If the pressure relief valve is leaking, replace the valve and recheck the pressure in the fuel rail.
f.If the pressure relief valve in the fuel rail is not leaking, check for fuel in the engine oil system. If fuel is suspected in the oil system,take an engine oil sample for analysis. Refer to Operation and Maintenance Manual, “Engine Oil Sample – Obtain”. If the analysis confirms that there is fuel in the engine oil system,investigate the cause.

g.If fuel is not found in the oil system, check the electronic unit injectors for excessive fuel leak off.
h.If the leak off is greater than 38 mL (1.3 oz) in 30 seconds for a 6 cylinder engine or the leak off is greater than 25 mL (0.85 oz) in 30 seconds for a 4 cylinder engine, replace the electronic unit injectors.
Note: The fault is not in the fuel rail pump. Do not replace the pump.
i.If the leak off is less than 38 mL (1.3 oz) in 30 seconds for a 6 cylinder engine or the leak off is less than 25 mL (0.85 oz) in 30 seconds for a 4 cylinder engine, proceed to Test Step 3.d.

3.If the absolute fuel rail pressure is greater than 25 MPa (3625 psi), perform the following procedure:
a.Use the electronic service tool to make sure that the status of the electronic unit injectors is not “Disabled”. If the injectors are disabled but the injectors were not intentionally disabled
with the electronic service tool, proceed to test step 3.d.
b.If the electronic unit injectors are not disabled,use the electronic service tool to perform an injector solenoid test. Refer to Troubleshooting,“Injector Solenoid Circuit – Test”.
c.If any service has been performed as a result of Step 3.b, attempt to start the engine. If the engine will not start, proceed to “Glow Plugs”.
d.Make sure that the latest flash file for the application is installed in the ECM. Refer to Troubleshooting, “Flash Programming”.
e.Contact Perkins Global Technical Support.
Note: This consultation can greatly reduce the repair time.
f.If Perkins Global Technical Support recommends the use of a test ECM, install a test ECM. Refer to Troubleshooting, “Replacing the ECM”.
g.Attempt to start the engine. If the engine will not start, install the original ECM and then proceed to Test Step 3.l.
h.If the engine starts normally, stop the engine and then attempt to start the engine again. If the engine will not start at the second attempt,proceed to Test Step 3.k.

If the engine starts normally, reconnect the suspect ECM and then verify that the fault returns when the suspect ECM is installed.
j.If the engine will not start with the suspect ECM, replace the ECM. Check that the engine starts normally. If the engine starts normally, no further testing is required.
k.Replace the ECM again and then replace the fuel rail pump. Verify that the fault has been eliminated. If the engine will not start, proceed to “Glow Plugs”.
l.Check the timing of the fuel rail pump. Refer to Systems Operation, Testing and Adjusting, “Fuel Injection Timing – Check”.
m.If the timing of the fuel rail pump required adjustment and the engine will not start,proceed to “Glow Plugs”.
n.If the timing of the fuel rail pump was correct,replace the fuel rail pump. If the engine will not start, proceed to “Glow Plugs”

Glow Plugs
Note: Faulty glow plugs will only affect engine starting when the ambient temperature is below 10 °C (50 °F).
1.Check the operation of the glow plugs.
2.If necessary, replace faulty glow plugs.
3.Attempt to start the engine. If the engine will not start, proceed to “Valve Lash”
