System Operation Description:Use this procedure if any of the following diagnostic code is active:
22-13 Engine Speed Signal Calibration Not Performed (42)A timing calibration must be performed under the following conditions:
The ECM has been replaced and the old ECM will not communicate with the Caterpillar Electronic Technician (Cat ET).
Work has been performed on the engine drive train (front).Note: The timing calibration will not increase the available engine power or the timing calibration will not decrease the available engine power. Do not expect an increase in power due to the performance of the timing calibration.Replacement ECMIf a replacement ECM is required, the ECM parameters and the timing calibration can be transferred from the suspect ECM to the replacement ECM. Timing calibration will not be necessary. This feature requires Cat ET and this feature is only possible if the existing ECM can communicate with Cat ET.

Part Number Description
6V-2197 Magnetic Transducer
7X-1695 Cable
7X-1111 Grommet
9S-9082 Engine Turning Tool
170-3519 Harness Test Step 1. Install the Transducer Adapter
Turn the key switch to the OFF position.
Remove the timing calibration plug from the left or the right front face of the flywheel housing.
Install the 7X-1171 Transducer Adapter into the hole for the plug.Results:
OK - Proceed to Test Step 2.Test Step 2. Install the 6V-2197 Magnetic Transducer on the Engine
Put a 2D-6392 O-Ring Seal on the end of the magnetic transducer.Note: A small amount of clean engine oil will allow the seal to slide onto the transducer more easily.
Push the magnetic transducer through the adapter until the magnetic transducer comes in contact with the outermost portion of the flywheel timing calibration ring. Move the O-ring seal downward against the adapter.
Withdraw the magnetic transducer 1.0 mm (0.04 inch) and hand tighten the nut on the adapter sleeve in order to secure the magnetic transducer in place.
Check that the probe is properly installed and snug. The probe should not move when the engine is started.
Connect the 6V-2197 Magnetic Transducer to the 7X-1695 Cable .
Install the 170-3519 Harness. Refer to Special Instruction, REHS0399, "Installation Of The 170-3519 Timing Calibration Harness Assembly On The 3126B Truck Engine" for the installation procedure.Results:
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 at low idle until the engine has warmed up enough to exit Cold Mode operation. The Cat ET status screen 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:
