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 while the engine is running will be disabled while 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 while the engine is running will be disabled while 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 in order to check the type of air filter restriction switch that is installed.
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 582-4
Running Closed E583-1 or 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 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".Note: Refer to the Electrical Schematic for the application while performing this procedure.

Troubleshooting Test Steps Values Results
1. Inspect Electrical Connectors and Wiring
A. Remove the electrical power from the ECM.
B. Thoroughly inspect the ECM connector J1/P1. Inspect all of the other connectors for the circuit. Refer to Troubleshooting, "Electrical Connectors - Inspect".
C. Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the circuit.
D. Check the ECM connector (allen head screw) for the correct torque of 5 N m (44 lb in).
E. Check the harness and the wiring for abrasion and for pinch points.
Loose connection or damaged wire
Result: There is a fault in a connector or the wiring.
Repair: Repair any faulty connectors or replace the wiring harness. Ensure that all of the seals are properly in place and ensure that the connectors are correctly coupled.
Result: The harness and wiring are OK.
Proceed to Test Step 2.
2. Check for Active or Logged Diagnostic Codes
A. Verify that the keyswitch is in the OFF position.
B. Connect the electronic service tool to the diagnostic connector.
C. Turn the keyswitch to the ON position.
D. Check
