(Table 232, contd)
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 be-
low 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.
Table233 contains the normal engine conditions and
switch states for the air filter restrictions switch.

Diagnostic Summary for a ““Normally Closed”” Air Filter Re-
striction Switch
Engine Condition
Switch State
Active Diagnostic
Code
Not running (key on) Closed Normal condition
Running Closed Normal Condition
(no air filter restric-
tion 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.
