RENR5042-02 69 Troubleshooting Section Possible Performance Effect: System Response: Engine misfires The Electronic Control Module (ECM) will not log this code. The Caterpillar Electronic Technician (ET) will not be able to clear the code. Engine shutdown Note: The engine will shut down only if the signals from the primary engine speed/timing sensor and the secondary engine speed/timing sensor are abnormal. Possible Performance Effect: Fuel injection is disabled. The engine will not start. Troubleshooting: Troubleshooting: Check the Part Number of the Flash File Perform the following diagnostic procedure: “Engine Speed/Timing Sensor Circuit - Test” Results: A.
Turn the keyswitch to the ON position. OK STOP. B. Verify that the part number for the flash file agrees with the latest update that is available on Service Technician Workbench (STW), or on SIS Web. i02048968 CID 0247 FMI 09 J1939 Data Link communications Expected Result: The correct flash file is installed in the ECM. Results: SMCS Code: 1901-038 OK – The correct flash file is installed in the ECM. Conditions Which Generate This Code: Repair: The engine will not start until the 253-02 diagnostic code is cleared. Clearing this code requires factory passwords. The Electronic Control Module (ECM) has detected a loss of communications with the J1939 data link. System Response:
Acquire factory passwords. Clear the 253-02 diagnostic code. Return the engine to service. The ECM will log the diagnostic code. STOP. Possible Performance Effect: Not OK – The correct flash file is not installed in the ECM. The engine may not operate properly. The equipment may not have engine speed control. Perform the following diagnostic procedure: “CAN Data Link Circuit - Test” Repair: Flash program the ECM with the correct flash file. Refer to Troubleshooting, “Flash Programming”. Verify that the problem is resolved. Results: STOP. OK STOP. i02214901 CID 0261 FMI 13 Engine Timing Calibration required i02265592 CID 0253 FMI 02 Personality Module mismatch SMCS Code: 1912-038 SMCS Code:
1902-038 Conditions Which Generate This Code: Conditions Which Generate This Code: The timing has not been calibrated since the Electronic Control Module (ECM) was installed or the calibration is incorrect. The flash file that is used for replacement is for a different engine family or for a different engine application. System Response: The ECM will log the diagnostic code.
