Note: If the selection for the harness code does not match the application, the Caterpillar Monitoring System may not operate correctly. The following list contains problems that the operator may encounter: the loss of event notification, incorrect data displays, incorrect gauge needle position and incorrect activation of diagnostic codes. CID 127 FMI 08, CID 177 FMI 08 and CID 819 FMI 02 are commonly caused by harness codes that are not correct for the application on new installations. Troubleshooting procedures are given for these diagnostic codes in the Testing And Adjusting Section of this Manual.
