G3516 TA Engine Caterpillar

Caterpillar Electronic Service Tools are designed to help the service technician perform the following functions:

• Obtain data.

• Diagnose problems.

• Read parameters.

• Program parameters.

• Calibrate sensors.

Connecting the Caterpillar Electronic Technician (Cat ET) to the Electronic Control Module (ECM)

Refer to Troubleshooting , "Electronic Service Tools" for a list of required tools and instructions.

Recommendations for Programming the System Configuration Parameters

The values of the parameters can be viewed on the "Configuration" screen of Cat ET.

Programmable parameters enable the engine to be configured to meet the requirements of the application. The system configuration parameters must be programmed when the application is installed. Perform this programming before the initial engine start-up.

Data from a gas analysis is required to determine the correct settings for the air/fuel ratio control. The data must be entered into Caterpillar Software , "Gas Engine Rating Pro (GERP)". Incorrect programming of parameters may lead to complaints about performance and/or to engine damage.

If an ECM is replaced, the appropriate parameters must be copied from the original ECM. This action can be done with the "Copy Configuration" feature of Cat ET. Alternatively, the settings can be recorded on paper and then programmed into the new module.

Note: Refer to Systems Operation, "Electronic Control System Parameters (Configuration Parameters)" for further information.

Changing the Settings of the Monitoring System

To change the settings of the parameters, use Cat ET and select the "Service/Monitoring System" screen.

Use care when you program the trip points and the delay times. Ensure that the response of the ECM is correct for the application. The monitoring system will accept any settings within the ranges.

Note: Refer to Systems Operation, "Engine Monitoring System" for further information.
