Service Tools and Diagnostics

20.2 Service Tools and Diagnostics

The control system has built-in diagnostics to verify system components are operating properly. In the event of a component failure, the driver is alerted to the condition via an OEM installed “Check Engine” or diagnostic lamp, or from a message transmitted over the SAE J1587 data link. Intermittent faults are logged and stored in the memory of the ECM and can be retrieved using an Electronic Service Tool. The recommended electronic service tool for the C-10, C-12, C-15 and C-16 engine is Caterpillar Electronic Technician (ET). ET is a software based service tool used to diagnose and repair Caterpillar products. It is designed to run on a personal computer using the Windows® 95 or Windows® NT operating system. Another Caterpillar service tool that can be used but is no longer supported, is the Electronic Control Analyzer and Programmer (ECAP). Caterpillar is also compatible with the MPSI Pro-Link service tool (requires Caterpillar cartridge). The following table outlines the capabilities of the electronic service tools mentioned. Note that the table outlines features as of the publication date. The MPSI Pro-Link Caterpillar cartridge allows all printable characters available on ET or ECAP except the following: ~, \, and _ characters. Therefore, for existing passwords containing these characters, ET or ECAP must be used. The Caterpillar ET or ECAP service tool allows the use of any printable character available on the keyboard. It is important when considering Customer passwords to make sure the service

tool normally used to access these parameters can input all the necessary characters.
