(1) P50 connector (2) 6V-3093 Transducer Adapter (3) 6V-2197 Magnetic Transducer (4) 7X-1695 Cable
Set the engine control to the OFF/RESET mode. Remove the timing calibration plug from either the left side or the right side of the flywheel housing. Install the 6V-3093 Transducer Adapter into the hole.
The timing hole in the flywheel must not be aligned with the hole for the transducer. The transducer will be damaged on engine start-up if the transducer is installed through both holes. Rotate the flywheel for more than 10 degrees before or after the TC position in order to move the flywheel hole away from the hole for the transducer. Always confirm that the holes are not aligned.
Make sure that the hole in the flywheel housing for the transducer is not aligned with the timing hole in the flywheel. Remove the protective end cap from the 6V-2197 Magnetic Transducer. Insert the transducer into the adapter until the transducer contacts the surface of the flywheel. Move the transducer 1 mm (0.04 inch) away from the surface of the flywheel. Tighten the nut on the adapter in order to secure the transducer in place.
Connect the one end of the 7X-1695 Cable to the transducer. Connect the other end of the cable to connector P50 inside of the terminal box.
Set the engine control to the STOP mode.
Connect Cat ET to the service tool connector on the terminal box. For instructions, refer to Troubleshooting, "Electronic Service Tools". Start Cat ET.Results:Continue to the next test step.Test Step 2. CalibrationNote: A two-step process is used to calibrate the signal for the speed/timing sensor. The new timing reference is calculated first. The reference is based on the signals from the transducer and the speed/timing sensor. Next, the new timing reference is programmed into the permanent memory of the master ECM.
Start the engine. Operate the engine at the rated speed and load.
Select "Service" from the main menu on Cat ET. Select "Calibrations" from the menu. Select "Timing Calibration".
Use either of the following methods in order to initiate the calculation of the new timing reference:
Press the space bar on the keyboard of the PC.
Click the left mouse button on the "Continue" button in the lower left corner of the Cat ET screen.Cat ET will indicate "Please wait...Calculating the new Timing Reference". After a few moments, Cat ET will display "The ECM has calculated the Timing Reference" and "Choose the Continue button to program the Timing Reference".
Use either of the following methods in order to program the new timing reference:
Press the space bar on the keyboard of the PC.
Click the left mouse button on the "Continue" button in the lower left corner of the Cat ET screen.Expected Result:After a few moments, Cat ET will display "CALIBRATION SUCCESSFUL".Results:
OK - The timing calibration was successful.STOP
Not OK - Cat ET displayed "COULD NOT CALIBRATE". The calibration was unsuccessful.Repair: If the calibration failed in the first step, verify that the engine rpm was stable during the calibration ( 50 rpm). Verify that there are no active diagnostic codes which can prevent the calibration. Repeat the calibration procedure.If the calibration is still unsuccessful, check the installation of the tools and the operation of the tools. Check the 7X-1695 Cable for continuity. Verify that the transducer is not bent, open, or shorted internally. Repeat the calibration procedure.Excessive backlash in the gear train will cause inconsistent timing. Refer to Disassembly and Assembly for identifying and repairing a gear train problem.STOP
Not OK - The calibration was completed successfully. However, the "261-13 Engine Timing calibration required" diagnostic code is still active.Repair: Replace the master ECM according to the instructions in Troubleshooting, "Replacing the ECM".STOP
