Troubleshooting Test Steps Values Results
3. Check the Supply Voltage to the Air Inlet Shutoff Solenoid
A. Connect Cat ET.
B. Use Cat ET to perform the following test:
- "Air Inlet Shutoff Override"
Note: If the Cat ET override is unavailable, use the "Emergency Stop Switch" to active the air shutoff system.
C. Measure the voltage across the two terminals of the air inlet shutoff solenoid.
Note: The ECM power supply output to the air shutoff relay is ON for 3 seconds then turns off. The power can only be measure at the solenoid during this duration if no override is available in Cat ET.
5 VDC of Battery Voltage
Result: The voltage is not within 5 VDC of battery voltage when the test is active. The air inlet shutoff solenoid is not receiving the correct signal.
Proceed to Test Step 4.
Result: The voltage is within 5 VDC of battery voltage when the test is active. The ECM is properly controlling the relay for the air inlet shutoff solenoid, but the air inlet shutoff solenoid is not working.
Repair: Replace the air inlet shutoff solenoid.
If the problem is not resolved, proceed to Test Step 4.
4. Check the Signal Voltage to the Relay
A. Connect Cat ET.
B. Use Cat ET to perform the following test:
- "Air Inlet Shutoff Override"
Note: If the Cat ET override is unavailable, use the "Emergency Stop Switch" to active the air shutoff system.
C. Measure the voltage across the relay coil.
5 VDC of Battery Voltage
Result: The voltage is within 5 VDC of battery voltage when the test is active.
Repair: The relay is receiving the signal from the ECM.
Proceed to Test Step 5.
Result: The voltage is not within 5 VDC of battery voltage when the test is active.
Repair: The relay is not receiving the signal from the ECM.
If the problem is not resolved, proceed to Test Step 7.
5. Check the Power Supply to the Relay
A. Measure the voltage between the following terminals:
- +Battery and Engine ground
5 VDC of Battery Voltage
Result: The voltage is within 5 VDC of
