PUMP GP-AUXILIARY SEA WATER 9Y5710 - Caterpillar

Use this procedure if a 261-13 Engine Timing Calibration required is active.Also use this procedure if any of the following conditions exist:
The Electronic Control Module (ECM) has been replaced.
The ECM software has been updated.
The front gear group has been serviced.The ECM has the ability to calibrate the mechanical differences between the Top Center (TC) of the No. 1 piston and the orientation of the camshaft. The ECM uses the signal from the primary engine speed/timing sensor as a control reference that identifies the exact orientation of the crankshaft. The ECM uses the signal that is detected from the secondary engine speed/timing sensor to identify the exact orientation of the camshaft.The two signals are then used by the ECM to calculate a timing offset. The offset is used by the ECM to calibrate the signal from the secondary engine speed/timing sensor. Note: A timing calibration will not increase the available engine power.Test Step 1. Check for Active Diagnostic Codes
Turn the keyswitch to the OFF position.
Connect the Caterpillar Electronic Technician (ET) to the service tool connector. Refer to Troubleshooting, "Electronic Service Tools".
Turn the keyswitch to the ON position.
Check for any active diagnostic codes. Expected Result:No active diagnostic codes are present.Results:
OK - No active diagnostic codes are present. If a timing calibration is necessary due to service to the ECM or to the front gear train, proceed to Test Step 2.
Not OK - 261-13 Engine Timing Calibration required is the only active diagnostic code that is present. Proceed to Test Step 2.
Not OK - There are active diagnostic codes. A 261-13 is not one of the active diagnostic codes.Repair: Troubleshoot the active diagnostic codes. Make the necessary repairs.STOP
Not OK - A 261-13 and other active diagnostic codes are present.Repair: Make the necessary repairs in order to resolve the active diagnostic codes. The 261-13 Engine Timing Calibration required may remain active while the repairs are made.Repeat Test Step 1.Test Step 2. Calibrate the Engine Speed/Timing Sensor
Start the engine. Run the engine until the engine has exited cold mode operation.
After the engine has warmed up, access the "Timing Calibration" screen on Cat ET. Access the following display screens in order:
"Service"
"Calibrations"
"Timing Calibration"
To calibrate the timing to the correct setting, set the engine speed to 1100 50 rpm and select "Continue" on Cat ET. Wait until Cat ET indicates that the timing is calibrated.
Press the "Continue" button on Cat ET. Wait until Cat ET indicates that the ECM has calculated the timing reference. Note: If Cat ET displays "Calibration Unsuccessful", the electronic injection timing has not been calibrated.Expected Result:The timing calibration was successful.Results:
OK - The timing calibration was successful.Repair: Return the engine to service.STOP
Not OK - The timing calibration was unsuccessful.Repair: The following conditions can cause the timing calibration to fail:
If the crankshaft and camshaft gears have been reassembled incorrectly, the timing will not calibrate.
Verify that the engine speed/timing sensors are installed correctly.
Verify that the engine speed is correct and that the engine speed is stable. If the engine speed is unstable, refer to
