Information:
Connect cable (2) to the RS-232 serial port of PC (1) .
Connect cable (2) to communication adapter (3) .
Connect cable (4) to communication adapter (3) .
Connect cable (4) to the service tool connector on the engine mounted CIP.
Turn the engine control switch to the LOCAL position or to the REMOTE position. Turn the fuel control switch to the FUEL OFF position. The engine should be OFF.If Cat ET and the communication adapter do not communicate with the ECM, refer to Troubleshooting, RENR5910, "Electronic Service Tool Will Not Communicate With ECM".Troubleshooting
Refer to Troubleshooting, RENR5084 for more information on the following components.

Injector faults
Response checks for the throttle input
Shutdown input response checksRequirements for the Electrical System
When you route the wiring, avoid acute bends and sharp edges. To protect the wiring harnesses, route the harnesses through a metal conduit. Use a rigid conduit or a use flexible conduit. A liquid tight conduit is recommended. Use proper support and alignment in order to avoid strain on the conduit.Electronic Service Tools
Caterpillar Electronic Service Tools are designed to help the service technician:
Obtain data.
Diagnose problems.
Read parameters.
Program parameters.
Calibrate sensors.The tools that are listed in Table 12 are required in order to enable a service technician to perform the electrical installation procedures and the initial start-up.Note: Other tools that are needed for measuring operating parameters such as pressure and temperature are not listed in Table 12.
