Troubleshooting Test Steps Values Results
1. Check for Codes
A. Establish communication between Cat® Electronic Technician (ET) and the Electronic Control Module (ECM) . Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Determine if a code is active or logged.
Codes
Result: A 3667-31, or E2087 (3) code is active or logged, or the air inlet shutoff valve is not working properly.
Proceed to Test Step 2.
Result: A 3239-5 or 2813-5 code is active or logged.
Proceed to Test Step 11.
Result: A 3239-6 or 2813-6 code is active or logged.
Proceed to Test Step 12.
Result: A 3667-2 or E2088 (1) code is active or logged.
Proceed to Test Step 13.
2. Perform the "Air Inlet Shutoff Override"
A. Turn the keyswitch to OFF.
B. Connect Cat ET to the service tool connector.
C. Turn the keyswitch to ON.
D. Place the transmission in neutral.
If the engine will not start, check the air inlet valve to ensure that the valve is not stuck closed.
E. Start the engine. Increase the engine speed to 1500 rpm 100 rpm.
F. Access the "Air Inlet Shutoff Override" in the "Diagnostic Tests" under the "Diagnostics" menu in Cat ET.
G. Start the test.
H. Wait for the engine to stop.
I. Stop the test.
Test
Result: The engine did not shut down.
Proceed to Test Step 5.
Result: The engine is shut down when the "Air Inlet Shutoff Override" is activated. The air inlet shutoff is working correctly.
Repair: Reset the air inlet shutoff system.
Proceed to Test Step 3.
3. Check the Air Inlet Shutoff Switch
A. Turn the keyswitch to ON.
B. Connect Cat ET to the service tool connector.
C. Use Cat ET to monitor the status for the air inlet shutoff switch while the switch is depressed.
Switch Works Correctly
Result: The status of the switch changed in Cat ET. The inlet air shutoff switch is operating properly.
Return to service.
Result: The status of the switch did not change in Cat ET.
Proceed to Test Step 4.
4. Check the Circuit to the Air Inlet Shutoff Switch
A.Turn the keyswitch to OFF.
B. Remove the air inlet shutoff switch.
C. Turn the keyswitch to ON.
D. Connect Cat ET to the service tool connector.
E. Short the terminals of the air inlet shutoff switch together. This will simulate the switch being closed.
F. Use Cat ET to monitor the status for the air inlet shutoff switch while the short is in place.
Circuit
Result: The status changed in Cat ET. The wiring is OK. The switch is not working properly.
Repair: Replace the air inlet shutoff switch. Verify that the repair eliminates the problem.
Result: The status did not change in Cat ET. There is a problem with the wiring between the ECM and the air inlet shutoff switch.
Repair: Inspect the wiring between the ECM and the air inlet shutoff switch. Repair the wiring or replace the wiring. Verify that the repair eliminates the problem.
5. Check the Transmission Neutral Switch
A. Verify that the transmission neutral switch is wired correctly.
If a transmission neutral switch is installed, the transmission must be in neutral.
B. Turn the keyswitch to ON.
C. Connect Cat ET to the service tool connector.
D. Monitor the status for the "Transmission Neutral Switch" while the transmission is in neutral. The status should be ON.
Transmission Neutral Switch
Result: The status of the transmission neutral switch is ON.
Proceed to Test Step 6.
Result: The status of the transmission neutral switch is OFF.
Repair: Refer to Troubleshooting, "Neutral Switch Circuit - Test".
6. Inspect Electrical Connectors and Wiring
A. Turn the keyswitch to OFF.
B. Thoroughly inspect the J2/P2 ECM connector and all other connectors in the circuit. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
C. Perform a 45 N (10 lb) pull test on the wires that are associated with the air inlet shutoff system.
D. Check the ECM connector (allen head screw) for the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
E. Check the harness and wiring for abrasion and for pinch points from the components back to the ECM.
Connectors
Result: All the wires and connections are OK.
Proceed to Test Step 7.
Result: There is a problem with the wiring.
Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all the seals are properly in place and ensure that the connectors are coupled.
Verify that the repair eliminates the problem.
7. Check the Supply Voltage to the Air Inlet Shutoff Solenoid
A. Connect Cat ET to the service tool connector.
B. Turn the keyswitch to ON.
C. Perform the "Air Inlet Shutoff Override" test in Cat ET.
D. Measure the voltage across the two terminals of the air inlet shutoff solenoid.
5 VDC
Result: The voltage is not within
