  • Page 39 Troubleshooting Procedures NCM Power Up LEDs The LED indicators supply evidence of the module’s condition and help determine that the module is functioning properly. See Figure 28. There are three sets of transmit (XMIT) and receive (RECV) LEDs, corresponding to the on-board N1 LAN circuit, the on-board N2 Bus circuit, and the submodule port.
  • Page 40 Self Diagnostics Microprocessor Indicators and Troubleshooting 1. Upon power up, the power LED lights and the NCM cycles through a self test. The sequence on the diagnostics display should read: 00, 11, 22, 33, 44, 55, 66, 77, 88, 99, and then 00 flashes between ten and twelve times before 88 displays.
  • Page 41 Table 3: Diagnostic Display, Descriptions, and Remedies Diagnostic Error Action Display Memory Error Reseat the NIM and cycle power. If the 01 error still occurs, either the NIM or the NCM is malfunctioning. (Catastrophic) If a known, good NIM fails in the slot, replace the NCM.
  • Page 42 • If possible, test the connections by installing a known functioning NCM module into the slot. During this procedure, disconnect the NCU from the N1 LAN (or ensure, via NCSETUP, that the node address of the functioning NCM will not conflict with any other address on the network).
  • Page 43 Rear View of Battery Submodule 200TC29 Figure 29: Measuring the Voltage of the Battery If the voltage is low, ensure that the battery is charged. A charging period of at least 15 minutes provides an accurate open circuit voltage reading. If the battery fails the open circuit test, perform the preliminary battery charger test (Step 2).
