RENR5042-02 181 Troubleshooting Section Table 23 a. Disconnect the P2 connector from the ECM. b. Remove the sealing plugs from P2-26 and P2-36. Do not discard the sealing plugs. The sealing plugs may be reinstalled when the timing calibration is complete. Note: Ensure that each wire is installed into the correct location. The timing calibration will not be successful if the wires are installed incorrectly. c. Install the white wire of the 170-3519 Harness into P2-26. d. Install the yellow wire of the 170-3519 Harness into P2-36. e. Connect the J2/P2 connectors. Tighten the allen head screw on the P2 connector to the appropriate torque.
Refer to Troubleshooting, “Electrical Connectors - Inspect” for the correct torque value. E. Remove the plug from the timing calibration port. F. Thread the transducer adapter into the port. f. Connect the 7X-1695 Cable As to the connector for timing calibration and to the transducer. Continue to the next test step. Test Step 2. Install the Transducer Continue to the next test step. NOTICE If the crankshaft is not in the correct position when the transducer is installed, the transducer will be damaged when the engine is started. Test Step 4. Start the Engine and Check for Diagnostic Codes A. Connect Caterpillar Electronic Technician (ET) to the service tool connector.
Refer to Troubleshooting, “Electronic Service Tools”. A. Apply clean engine oil to a 2D-6392 O-Ring Seal. Install the O-ring seal on the end of the 6V-2197 Transducer. B. Start the engine and run the engine until the engine is at the normal operating temperature. C. Check for active diagnostic codes. B. Push the transducer through the transducer adapter until the transducer contacts the crankshaft counterweight. The engine must not have any active diagnostic codes during the timing calibration except for a 261-13 Engine Timing Calibration required. C. Withdraw the transducer 1.0 mm (0.04 inch) and hand tighten the nut on the adapter sleeve in order to secure the transducer.
Move the O-ring seal against the adapter. Expected Result: There are no active diagnostic codes or there is only an active 261-13 diagnostic code. Continue to the next test step. Test Step 3. Connect the 7X-1695 Cable As Results: A. If the engine harness is equipped with a connector for timing calibration, connect the 7X-1695 Cable As to the connector for timing calibration and to the transducer. OK There are no active diagnostic codes or there is only an active 261-13 diagnostic code. Proceed to Test Step 5. Not OK There is at least one active code that is not 261-13. B. If the engine harness is not equipped with a connector for timing calibration, perform the following procedure:
