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 is a "Normally Closed" switch.Table2 contains the normal engine conditions and switch states for the air filter restrictions switch.
Table 2
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 3
Troubleshooting Test Steps Values Results
1. 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. Install a jumper wire in the wiring harness connector between the signal and ground terminals.
D. Turn the keyswitch to ON.
E. Monitor the electronic service tool for active fault codes.
Diagnostic codes
Results : There is not an active 107-3 or 582-3 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 107-3 or 582-3 diagnostic code. An open circuit in the wiring harness has been detected.
Repair : Repair or replace the wiring harness.
Verify that the repair has eliminated the issue.
If the fault is still present, contact the Dealer Solutions Network (DSN).
