Part Number Description
7X-1171 Transducer Adapter
6V-2197 Transducer
7X-1695 Cable As
170-3519 Harness Test Step 1. Check for Active Diagnostic Codes
Remove electrical power from the ECM.
Connect the Caterpillar Electronic Technician (ET) to the service tool connector. Refer to Troubleshooting, "Electronic Service Tools".
Restore electrical power to the ECM.
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. Install the Transducer Adapter
Remove electrical power from the ECM.
Illustration 1 g01138837
Flywheel and flywheel housing (typical example)
(1) Timing calibration plug
(2) Timing pin hole
Remove timing calibration plug (1) from either side of the flywheel housing.
Use a flashlight to examine the flywheel through the timing calibration port that is in the flywheel housing. Ensure that timing pin hole (2) that is machined into the flywheel is not aligned with the hole that is in the flywheel housing. If necessary, rotate the crankshaft in order to cause the misalignment of the holes.
Install the 7X-1171 Transducer Adapter into the timing calibration port that is in the flywheel housing. Results:Continue to the next test step.Test Step 3. Install the Transducer
Do not install the timing calibration probe over the timing pin hole in the flywheel. Damage to the timing calibration probe will result if the probe is installed over the timing pin hole.
Apply clean engine oil to a 2D-6392 O-Ring Seal. Install the O-ring seal on the end of the 6V-2197 Transducer.
Insert the 6V-2197 Transducer through the transducer adapter. Insert the transducer until contact is made with the surface of the flywheel. Pull the transducer 1.0 mm (0.04 inch) away from the flywheel.
Tighten the nut on the transducer adapter.
Connect the 7X-1695 Cable As from the engine timing calibration probe to the P40 TC probe connector. Note: Some engines may not have a P400 timing calibration probe connector as part of the engine harness. A 170-3519 Harness may be required. Refer to the appropriate Schematic for the engine that is being serviced for the pin-outs to use for this harness.Results:Continue to the next test step.Test Step 4. 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: Perform the following procedure:
Set the engine speed to low idle. Note: Disconnect the 7X-1695 Cable As before you exit the "Timing Calibration" screen. Otherwise, diagnostic codes may be activated.
Disconnect the 7X-1695 Cable As.
Exit the "Timing Calibration" screen on Cat ET.
Remove electrical power from the ECM.
Remove the transducer and remove the adapter.
Install the plug into the timing calibration port.
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 timing calibration probe is installed correctly.
Verify that the engine speed is correct and that the engine speed is stable. If the engine speed is unstable, refer to Troubleshooting, "Engine Misfires, Runs Rough or Is Unstable".
There may be a problem with the transducer or with the cables. Obtain a new transducer and/or a new cable and repeat the timing calibration.STOP
