Required Tools
Part Number Description
6V-2197 Transducer
7X-1695 Cable As
7X-1171 Transducer Adapter
9S-9082 Engine Turning Tool
170-3519 Harness Test Step 1. Install the 7X-1171 Transducer Adapter.
Turn the keyswitch to the OFF position.
Use the 9S-9082 Engine Turning Tool to put either the No. 1 piston or the No. 6 piston at top center. Refer to Testing and Adjusting, "Finding the Top Center Position for the No. 1 Piston" for additional information. Note: Normal engine rotation is counterclockwise as the engine is viewed from the flywheel end. Refer to Illustration 1.
Use the following procedure for C7 engines.
Rotate the engine in the direction of the normal engine rotation by the following amount:
100 Degrees
Remove the timing calibration plug from the engine. If the engine is viewed from the flywheel, the timing calibration plug is located on the left side in the No. 3 cylinder rod pocket.
Use the following procedure for C9 engines.
Rotate the engine in the direction of the normal engine rotation by the following amount:
85 Degrees
Remove the timing calibration plug from the engine. If the engine is viewed from the flywheel, the timing calibration plug is located on the left side in the No. 3 cylinder rod pocket.
Install the 7X-1171 Transducer Adapter into the port for the plug. Results:
OK - Proceed to Test Step 2.Test Step 2. Install the 6V-2197 Transducer on the Engine
If the crankshaft is not in the correct position when the 6V-2197 Transducer is installed, the Magnetic Transducer (TC Probe) may be damaged when the engine is started.
Put a 2D-6392 O-Ring Seal on the end of the transducer. Note: A small amount of clean engine oil will allow the seal to slide onto the transducer more easily.
Push the sensor through the adapter until the transducer comes in contact with the outermost portion of the crankshaft counterweight. Move the O-ring seal downward against the adapter.
Withdraw the transducer 1.0 mm (0.04 inch) and hand tighten the nut on the adapter sleeve in order to secure the transducer.
Check that the transducer is properly installed and snug. The transducer should not move when the engine is started.
Connect the 6V-2197 Transducer to the 7X-1695 Cable As.
Install the 170-3519 Harness. Connect the white wire to J2/P2-22 Engine Timing Calibration Probe +. Connect the yellow wire to the ECM at J2/P2-23 Engine Timing Calibration Probe -.
Connect the 7X-1695 Cable to the 170-3519 Harness.
Ensure that all of the following connections are made correctly:

OK - Proceed to Test Step 3.Test Step 3. Start the Engine and Allow the Coolant to Reach Operating Temperature
Start the engine and run the engine at low idle until the engine is at the correct operating temperature. Note: The status screen on Cat ET will display "COLD MODE" in the upper corner when cold mode operation exists. The engine will adjust idle rpm from cold mode idle to the programmed low idle rpm when cold mode operation is complete.
Check for active diagnostic codes. Use the procedures in this manual to troubleshoot and repair any active diagnostic codes before attempting a calibration check. The engine must not have any diagnostic fault conditions that are present during the timing calibration except the following condition:
22-13 Engine Speed Signal Calibration Not Performed
Once the engine is warm, set the engine speed to 1100 rpm with the cruise control switches or with the accelerator pedal. Note: The engine rpm must be steady within the 1050 to 1150 rpm range in order to perform a timing calibration.Results:
OK - Proceed to Test Step 4.Test Step 4. Connect Cat ET
Connect Cat ET to the data link connector.
After the engine has exited cold mode, access the "Timing Calibration" screen on Cat ET. Access the following display screens in order:
"Service"
"Calibrations"
"Timing Calibration"Note: To perform a timing calibration, the engine rpm must remain as steady as possible at approximately 1100 rpm. This can be performed with the cruise control switches or a steady foot on the accelerator pedal. Any changes to engine rpm that are more than 100 rpm will slow down the procedure. These changes will also reduce the accuracy of the procedure.Results:
OK - Proceed to Test Step 5.Test Step 5. Calibrate the Speed/Timing Sensor
To calibrate the timing to the correct setting, select "Continue" on Cat ET. Wait until the Cat ET indicates that the timing is "CALIBRATED". Note: If Cat ET displays "CALIBRATION UNSUCCESSFUL", the electronic injection timing has not been set. Recheck the tool installation and tool operation and try again to calibrate electronic inject
