Information:
Step 1. Check for Active +5 V Sensor Supply Diagnostic Codes
Connect the Caterpillar Electronic Technician (Cat ET) to the data link connector.
Turn the keyswitch to the ON position. Wait at least 15 seconds for activation of the diagnostic codes.
Verify if any of the following diagnostic codes are active:
262-03 5 Volt Sensor DC Power Supply short to +batt
262-04 5 Volt Sensor DC Power Supply short to groundExpected Result:None of the preceding diagnostic codes are active.Results:
OK - Proceed to Test Step 2.
Not OK - There are active diagnostic codes for the 5 Volt sensor supply.Repair: Perform the following diagnostic procedure: Troubleshooting, "Analog Sensor Supply Circuit - Test". Stop.Test Step 2. Inspect Electrical Connectors And Wiring
Thoroughly inspect the J2/P2 ECM connector, and the connectors for any suspect sensors. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector and in the sensor connectors that are associated with the active diagnostic code.
Check the ECM connector (Allen head screw) for the proper torque of 2.25 N m (20 lb in).
Check the harness and wiring for abrasion and for pinch points from the sensors back to the ECM.Expected Result:All connectors, pins and sockets are completely coupled and/or inserted and the harness and wiring are free of corrosion, of abrasion and of pinch points.Results:
OK - Proceed to Test Step 3.
Not OK - Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the seals are properly in place and ensure that the connectors are completely coupled.Verify that the repair eliminates the problem.Clear all logged diagnostic codes. Stop.Test Step 3. Determine the Condition that is Present
Turn the keyswitch to the ON position. Wait at least 15 seconds for activation of the diagnostic codes.
Monitor the active diagnostic code screen on Cat ET.
Determine if the problem is related to an open circuit diagnostic code or a short circuit diagnostic code.Expected Result:Either an open circuit diagnostic code or a short circuit diagnostic code is active.Results:
Short Circuit - A short circuit diagnostic code is active at this time. Proceed to Test Step 4.
Open Circuit - An open circuit diagnostic code is active at this time. Proceed to Test Step 7.Test Step 4. Disconnect the Suspect Sensor
Turn the keyswitch to the OFF position.
Disconnect the sensor with the short circuit diagnostic code.
Turn the keyswitch to the ON position. Wait at least 15 seconds for activation of the diagnostic codes.
Check for an active open circuit diagnostic code for the disconnected sensor.Expected Result:An open circuit diagnostic code is now active for the disconnected sensor.Results:
OK - A short circuit diagnostic code was active before disconnecting the sensor. An open circuit diagnostic code became active after disconnecting the sensor.Repair: Temporarily connect a new sensor.Check for active diagnostic codes.If the new sensor fixes the problem, reconnect the suspect sensor.If the problem returns, permanently install the new sensor.Verify that the repair eliminates the problem. Stop.
Not OK - There is a short circuit between the sensor and the
