Table 1
Diagnostic Trouble Codes for the Air Filter Restriction Switch
J1939 Code CDL Code Code Description
(Code descriptions may vary) Comments
107-3 582-3 Air Filter Differential Pressure Switch voltage above normal This code indicates a fault in the circuit for the air filter restriction switch.
The Electronic Control Module (ECM) detects the following conditions:
The air filter restriction switch circuit is open for at least 1 second.
The engine is not running.
Monitoring of air filter restriction when the engine is running will be disabled whilst this code is active.
107-4 582-4 Air Filter Differential Pressure Switch voltage below normal This code indicates a fault in the circuit for the air filter restriction switch.
The Electronic Control Module (ECM) detects the following conditions:
The air filter restriction switch circuit is grounded for at least 1 second.
The engine is not running.
Monitoring of air filter restriction when the engine is running will be disabled whilst this code is active. The engine is equipped with an air filter restriction switch. The type of switch that is installed can be a "Normally Open" switch or a "Normally Closed" switch.Use the electronic service tool to check the configuration parameters to check the type of air filter restriction switch that is installed.Tables 2 and 3 contain the normal engine conditions and switch states for the air filter restrictions switch.
Table 2
Diagnostic Summary for a "Normally Open" Air Filter Restriction Switch
Engine Condition Switch State Active Diagnostic Code
Not running (key on) Open Normal condition
Running Open Normal Condition (no air filter restriction detected)
Not running (key on) Closed 107-4 (582-4)
Running Closed 107-15 (E583-1) or 107-16 (E583-2) (air filter restriction detected)
Table 3
Diagnostic Summary for a "Normally Closed" Air Filter Restriction Switch
Engine Condition Switch State Active Diagnostic Code
Not running (key on) Closed Normal condition
Running Closed Normal Condition (no air filter restriction detected)
Not running (key on) Open 107-3 (582-3)
Running Open 107-15 (E583-1) or 107-16 (E583-2) (air filter restriction detected) Note: A 107-15 (E583-1) or a 107-16 (E583-2) diagnostic code indicates that the air inlet is restricted. Refer to Troubleshooting, "Inlet Air Is Restricted".During the following procedure, refer to the electrical schematic for the application.Complete the procedure in the order in which the steps are listed.
Table 4
Troubleshooting Test Steps Values Results
1. Check the "Air Filter Restriction Switch Configuration"
A. Turn the keyswitch to ON.
B. Connect the electronic service tool to the diagnostic connector.
C. Under "Configuration Parameters", check the "Air Filter Restriction Switch Configuration".
Air Filter Restriction Switch Configuration
Results : The switch is configured to "Normally Open".
Proceed to Test Step 2.
Results : The switch is configured to "Normally Closed".
Proceed to Test Step 3.
2. Check the Air Filter Restriction Switch
A. Turn the keyswitch to OFF.
B. Disconnect the air filter restriction switch from the wiring harness connector.
C. Turn the keyswitch to ON.
D. Monitor the electronic service tool for active fault codes.
Diagnostic codes
Results : There is not an active 107-4 (582-4) diagnostic code. A failed air filter restriction switch has been detected.
Repair : Replace the air filter restriction switch.
Verify that the repairs eliminated the issue. Return the machine to service.
Results : There is an active 107-4 (582-4) diagnostic code.
