FILTER ELEMENT-AIR 1635865 - Caterpillar

Replacing the Engine Control Module (ECM) with the Use of the ECM Replacement Feature from the Electronic Service Tools
Ensure that the ECM is the problem by first connecting a test ECM. This is a temporary connection. Hang the test ECM on the side of the engine. Refer to Troubleshooting, "Test ECM Mode".
If the test ECM repairs the problem, reconnect the suspect ECM. Verify that the problem returns when the suspect ECM is reconnected.
Select the ECM Replacement Feature under the "Service/Copy Configuration" menu and load the parameters from the failed ECM.
Temporarily connect the new ECM by connecting both ECM connectors. Do not mount the ECM on the engine yet.
Flash program the personality module into the new ECM if the personality module is not already installed. The new ECM is shipped with a blank personality module.
Use the ECM replacement feature in Caterpillar Electronic Technician (ET) in order to program the new ECM.
Enter the value for the "Rating Number" parameter into the new ECM.
Check for active codes. Program any required parameters that have not been programmed. Note: On initial powerup of a new ECM, the parameter "Rating Number" must be programmed to avoid activating a 253-02 diagnostic code.
If the 22-13 diagnostic code is not active, install the new ECM on the engine. Otherwise, perform a timing calibration first. Replacing the ECM without the Use of the ECM Replacement Feature from the Electronic Service Tool
Ensure that the ECM is the problem by first connecting a test ECM. This is a temporary connection. Hang the test ECM on the side of the engine. Flash program the identical Personality Module that was used in the suspect ECM into the test ECM. Program any parameters that are necessary to use the ECM for the test. For example, Vehicle speed parameters need to be programmed to check the vehicle speed circuit. Program the parameters in the test ECM to be equal to the parameters in the suspect ECM.
If the test ECM repairs the problem, reconnect the suspect ECM. Verify that the problem returns when the suspect ECM is reconnected.
Obtain customer parameters from the failed ECM.
Obtain the customer passwords and record the customer passwords. If the customer (owner) has lost the passwords or if the customer (owner) has forgotten the passwords, proceed to Troubleshooting, "Customer Passwords" for more details.
Use Cat ET to access customer specified parameters from the ECM that is being replaced. If the ECM does not communicate with the electronic service tool, obtain the required parameter list from the OEM.
Use the Troubleshooting, "Customer Specified Parameters Worksheet" to record the customer parameters.
Record the serial number for the unit injectors. The serial numbers for the unit injectors can be found on the "Injector Trim Calibration" in "Calibrations" under the "Service" menu on Cat ET. Refer to Troubleshooting, "Injector Code - Calibrate" for more information.
Record ECM lifetime totals.
Use the Troubleshooting, "Customer Specified Parameters Worksheet (Current Totals Worksheet)" in order to record the old "ECM Current Totals".
Temporarily connect the new ECM by connecting both ECM connectors. Do not mount
