Troubleshooting Test Steps Values Results
1. Check for "Active" or "Logged" Diagnostic Codes
A. Connect Caterpillar Electronic Technician (ET) to the service tool connector.
B. Restore the electrical power to the ECM.
C. Monitor the diagnostic codes on Cat ET. Check and record any diagnostic codes.
Note: Wait at least 30 seconds in order for the diagnostic codes to become active.
D. Determine if the problem is active and related to one of the following diagnostic codes:
-3
-4
Codes
Result: No diagnostic codes are active at this time.
Repair: The problem may be intermittent. If the problem is intermittent refer to Troubleshooting, "Electrical Connectors - Inspect".
Result: An active -3 diagnostic code is present.
Proceed to Test Step 2
Result: An active -4 diagnostic code is present.
Proceed to Test Step 4
2. Check for a Short to the +Battery at the Sensor Connector
A. Measure the voltage on the harness side of the sensor connector between pin 1 and pin 2 for the suspect sensor.
+Battery
Result: The supply voltage is less than Battery voltage.
Proceed to Test Step 3.
Result: The supply voltage is equal to Battery voltage.
Repair: There is a short in the harness to the +Battery. Repair the wiring.
Verify that the repair eliminated the problem.
3. Create a Short at the Sensor Connector
A. Turn the main disconnect switch to the OFF position.
B. Disconnect the suspect sensor.
C. Use a wire jumper in order to create a short between terminal 1 (signal) and terminal 2 (sensor return) at the sensor connector.
D. Restore the electrical power to the ECM.
E. Access the "Active Diagnostic Code" screen on Cat ET. Check for an active -4 diagnostic code for the suspect sensor.
Note: Wait at least 30 seconds in order for the diagnostic codes to become active.
F. Turn the main disconnect switch to the OFF position.
Short
Result: A -3 diagnostic code was active before creating the short at the sensor connector. A -4 diagnostic code became active after creating the short at the sensor connector.
Repair: Temporarily connect a new sensor to the harness, but do not install the new sensor in the engine. Verify that there are no active diagnostic codes for the sensor. If there are no active diagnostic codes for the sensor, permanently install the new sensor. Clear any logged diagnostic codes.
Verify that the repair eliminated the problem.
Result: A -3 diagnostic code is still active for the suspect sensor.
Proceed to Test Step 5
4. Create an Open at the Suspect Sensor Connector
A. Disconnect the sensor connector of the suspect sensor with the active -4 diagnostic code.
B. Restore the electrical power to the ECM.
C. Access the "Active Diagnostic Code" screen on Cat ET. Check for an active -3 diagnostic code.
Note: Wait at least 30 seconds in order for the diagnostic codes to become active.
D. Turn the main disconnect switch to the OFF position.
Open
Result: A -4 diagnostic code was active before disconnecting the sensor. A -3 diagnostic code became active after disconnecting the sensor.
Repair: Temporarily connect a new sensor to the harness, but do not install the new sensor in the engine. Verify that there are no active diagnostic codes for the sensor. If there are no active diagnostic codes for the sensor, permanently install the new sensor. Clear any logged diagnostic codes.
Verify that the repair eliminated the problem.
Result: A -4 diagnostic code is still active for the suspect sensor. There is a short circuit between the sensor connector and the ECM. Leave the sensor disconnected.
Proceed to Test Step 5
5. Check the Operation of the ECM
A. Check the operation of the ECM by creating an open at the ECM.
B. Remove the signal wire for the suspect sensor from the P2 ECM connector. Refer to Illustration 1 for terminal locations.
C. Fabricate a jumper wire that is long enough to create a test circuit between the ECM connector and the ECM ground strap. Crimp a connector socket to one end of the jumper wire.
E. Install the jumper wire into the terminal location of the signal wire
