120 RENR5042-02 Troubleshooting Section Not OK – The correct flash file is not installed in the ECM. B. Review the system configuration parameters and the engine lifetime totals. Repair: Program the correct flash file into the ECM. Refer to Troubleshooting, “Flash Programming”. Verify that the problem is resolved. Expected Result: The parameters and totals are correct. STOP. Results: Test Step 4. Determine the Parameters that Require Programming OK – The parameters and totals are correct. Repair: Return the engine to service. A. Place the engine control in the ON mode. STOP. B. Verify that the configuration parameters are correct for the engine’s application.
Refer to Troubleshooting, “System Configuration Parameters”. Not OK The parameters and/or the totals are incorrect. Expected Result: Repair: Try to program the suspect parameter or parameters. Refer to Troubleshooting, “System Configuration Parameters”. The configuration parameters are correct. If the programming is successful, clear the code and return the engine to service. Results: OK – The configuration parameters are correct. If the parameters cannot be programmed, replace the ECM. Refer to Troubleshooting, “Replacing the ECM”. Clear the diagnostic code and return the engine to service. Repair: Clear the diagnostic code and return the engine to service. STOP. STOP.
Not OK The configuration parameters are not correct. i02250507 Electrical Connectors - Inspect Repair: The 268-02 diagnostic code cannot be cleared until all of the parameters are programmed with the correct values. The engine may use a default torque map or the ECM may limit the engine to low idle until this diagnostic code is cleared. SMCS Code: 7553-040-WW System Operation Description: Most electrical problems are caused by poor connections. The following procedure will assist in detecting problems with connectors and with wiring. If a problem is found correct the condition and verify that the problem is resolved. Try to program the configuration parameters.
Refer to Troubleshooting, “System Configuration Parameters”. If the programming is successful, clear the code and return the engine to service. Intermittent electrical problems are sometimes resolved by disconnecting and reconnecting connectors. It is very important to check for diagnostic codes immediately before disconnecting a connector. Also check for diagnostic codes after reconnecting the connector. If the status of a diagnostic code is changed due to disconnecting and reconnecting a connector, there are several possible reasons. The likely reasons are loose terminals, improperly crimped terminals, moisture, corrosion, and inadequate mating of a connection.
If the parameters cannot be programmed, replace the ECM. Refer to Troubleshooting, “Replacing the ECM”. Clear the diagnostic code and return the engine to service. STOP. Test Step 5. Review the Parameters and Data A. Turn the keyswitch to the ON position. Follow these guidelines:
