Connect Cat® Electronic Technician to the machine. Turn the Key Start switch to the RUN position. Start Cat ET. Cat ET initiates communications with the Electronic Control Modules on the machine. After communication has been established, Cat ET lists the Electronic Control Modules. Choose the desired Electronic Control Module (ECM). Once the ECM has been selected, click "Diagnostics" on the tool bar and choose "Logged Diagnostic Codes" from the submenu. After the diagnostic codes have been identified, refer to the test procedure for the corresponding diagnostic code.Reference: Troubleshooting, "Service Tools"Logged Diagnostic Codes

Note: Before performing a procedure, always check all the circuit breakers. Repair the cause of any circuit breaker that is tripped.Test procedures may cause new active or logged diagnostic codes. Therefore, before any procedures are performed, make a list of all logged diagnostic codes to determine system problems. Clear any diagnostic codes that were caused by the procedure, when each procedure is complete. To view the active diagnostic codes, click "Diagnostics" on the tool bar and choose "Active Diagnostic Codes" from the submenu.A screen is provided in Cat ET for active diagnostic codes. The screen will display the diagnostic codes that are active. Active diagnostic information shall include a component identifier (CID), a failure mode identifier (FMI) and a text description of the problem.A screen is provided in Cat ET for logged diagnostic codes. The screen will display diagnostic codes that are logged. Cat ET will log diagnostic codes that are intermittent. The logged diagnostic data include a component identifier (CID), a failure mode identifier (FMI), and a text description of the problem. Also, the logged diagnostic data shall include the number of occurrences of the problem and two time stamps. The time stamp displays the first occurrence of the problem and the time stamp displays the most recent occurrence of the problem.Diagnostics are logged in non-volatile memory. On powerup, the ECM will clear any diagnostic codes that have not been detected or active within the last 150 hours of machine operation.
