Tools for Electronic Engines
Caterpillar Electronic Technician is now fully integrated with Caterpillar Guided Diagnostics for On-Highway truck engines. This allows the service technician to effectively troubleshoot Active/Logged Diagnostic Codes, view wiring schematics, diagrams and access technical documentation. The technician can start GuidedDiagnostics from the ET diagnostic code screen, from the ET Menu Bar or Icon Bar, or from the PC Desktop if the ECM cannot communicate with ET. Serial number prefixes covered by Guided Diagnostics with ET include: 9CK, 2PN, 1YN, 5EK, 6TS, 1WM, 4ES, 8WL, 7LG, 2YG, 4CK, 2EK, 5YG, 8TC.

The functions listed below can also provide important data to improve operation and maintenance of equipment and increase profitability.

  • Cat “ET Trainer” is now included in ET Program. It allows users to train and practice using Cat ET without a communications adapter or Electronic Control Module (ECM). This is a free feature of Cat ET.
  • ECM Summary screen lists every control module on equipment being tested and gives information on these modules.
  • Fast hookup and real time display of systems status. Displays readings such as rpm, boost, pressures, temperatures, etc. for easy troubleshooting.
  • Identifies faulty sensors, harness connectors, and system parameters which are out of specification. Allows customers to help dealer identify problems without visiting machine.
  • Identifies intermittent sensors and wiring problems during machine operation and keeps a record of each one. Shows when problem occurred and how often it happened. Provides added information to allow customer to assist dealer in diagnosing and repairing problems.
  • Shows all operating conditions that cause high repair costs such as: overspeeds, high temperatures, fuel consumption, and transmission shift counts. This can provide awareness to change operator techniques resulting in lower machine operating and maintenance costs.
  • Tests are provided such as cylinder cutout and injector activation pressure to make problem locating easy.
