Diagnostic Trouble Codes
Table 1 lists the diagnostic trouble codes that apply to the engines that are covered in this manual. Use the Caterpillar Electronic Technician (ET) to determine the codes that are active or logged. Then refer to the appropriate troubleshooting procedure for more information.
Note: A requirement for all troubleshooting is that the troubleshooting is based on active and/or passive diagnostic trouble codes. Do not troubleshoot based on flash codes alone.
