If the flash file and engine application are not matched, engine damage may result.
Perform the following procedure to replace the ECM:
Record the configuration data:
Try to establish communication between the Cat® Electronic Technician (ET) and the ECM. Proceed to Test Step 2 if Cat ET does not communicate with the ECM.
Print the parameters from the "Configuration" screen on Cat ET. If a printer is unavailable, record all the parameters.
Obtain the customer passwords. Access the customer specified parameters with Cat ET. Record the value of each customer parameter.
Record ECM lifetime totals.________
Record any logged diagnostic codes. ________Note: If the customer passwords are not available, proceed to Troubleshooting, "Customer Passwords" for details that are related to customer passwords.
Use the "Copy Configuration/ECM Replacement" feature that is found under the "Service" menu on Cat ET. Select "Load from ECM" to copy the configuration data from the suspect ECM.Note: If the "Copy Configuration" process fails and the parameters are not obtained in Step 4g, the parameters must be obtained elsewhere. Some of the system configuration parameters are stamped on the engine information plate. Most of the parameters must be obtained from the factory. Parameters that are related to customer specified parameters must be obtained from the customer or from the Original Equipment Manufacturer (OEM).
Remove the ECM:
Remove the electrical power from the ECM.
Disconnect the P1 and P2 connectors.
Use a suitable container to catch any fuel that might spill. Clean up any spilled fuel immediately.
Do not allow dirt to enter the fuel system. Thoroughly clean the area around a fuel system component that will be disconnected. Fit a suitable cover over any disconnected fuel system components.
Remove the fuel lines (if equipped) from the ECM.
Disconnect the ECM ground strap.
Remove the mounting hardware at each corner of the ECM.
Install the replacement ECM:
Use the old mounting hardware to install the replacement ECM.
Reconnect the fuel lines (if equipped).Note: Ensure that the ECM mounting hardware is installed correctly. The rubber grommets are used to protect the ECM from excessive vibration. The ECM must be able to drift in the rubber grommets. If the installation is equipped with fuel lines, the fuel lines must not put tension on the ECM.
Connect the ECM ground strap.
Connect the P1 and P2 connectors. Refer to Troubleshooting, "Electrical Connectors - Inspect" for the correct torque values.
Configure the replacement ECM:
Flash program the latest available flash file into the ECM. Refer to Troubleshooting, "ECM Software - Install" for the correct procedure.
Use Cat ET to match the engine application and the interlock code if the replacement ECM was used for a different application.
If the "Copy Configuration" process from Step 4g was successful, return to the "Copy Configuration/ECM Replacement" screen on Cat ET and select "Program ECM".After using the "Program ECM" feature, be sure to cycle the power to the ECM. Wait at least 30 seconds after turning the keyswitch to the OFF position.Note: Some control modules have a power off delay. The 30 seconds will be sufficient to cover this delay.
Proceed to Step 4f when programming is complete.
If the "Copy Configuration" process from Step 4g was unsuccessful, manually program the ECM parameters. The parameters must match the parameters from Step 4g.
Program the engine monitoring system, if necessary.
If necessary, install the injector trim files. Refer to Troubleshooting, "Injector Trim File - Install".
