DTC31 \"'
DRIVER LOOP ENERGY RESERVE FEED OPEN
CIRCUIT DESCRIPTION
During the "Continuous Monitoring" tests the DERM
monitors the
voltage at "Driver Source Sense" terminal
"AS." When the circuit is operating normally the
measured voltage will be slightly less than "Driver 36
VLR."
If the "Driver 36 VLR" circuit opens the voltage
measured at "Driver Source Sense" will decrease to
slightly less than "Ignition 1" voltage. When the voltage
measured at "Driver Source Sense" is within a specified
range of
"Ignition 1" for SOO milliseconds DTC 31 is set.
DTC WILL SET WHEN
The voltage measured at "Driver Source Sense" terminal
"AS"
is within a specified range of "Ignition 1" for SOO
milliseconds. This test is run every 100 milliseconds
during "Continuous Monitoring" tests.
ACTION TAKEN
DERM turns "ON" the "AIR BAG" warning lamps and sets
a diagnostic
trouble code.
DTC WILL CLEAR WHEN
The voltage measured at "Driver Source Sense" terminal
"AS"
is outside the specified range of "Ignition 1" which
sets the diagnostic
trouble code, for SOO milliseconds.

DTC CHART TEST DESCRIPTION
Number(s) below refer to step number(s) on the
diagnostic chart.
2. This test checks for an open in the "Driver 36VLR"
circuit.
3. This test checks for a high resistance, but not an
open, in the "Driver Source Sense" circuit.
4. This test checks for a short from the "Driver Source
Sense" circuit to 8+.
s. This test determines whether the malfunction is due
to the
dual pole arming sensor.
DIAGNOSTIC AIDS
An intermittent condition is likely to be caused by a poor
connection at arming sensor
terminal "4" or "6", poor
connection at DERM
terminal "A4" or "AS", an open in
CKT 1811 or CKT 1812, or an open inside the dual pole
arming sensor.

PASSENGER LOOP ENERGY RESERVE FEED OPEN
CIRCUIT DESCRIPTION
During the "Continuous Monitoring" tests the DERM
monitors the voltage at
"Passenger Source Sense"
terminal "AS". When the circuit is operating normally the
measured voltage
will be slightly less than "Passenger
3S VLR." If the "Passenger 3S VLR" circuit opens the
voltage measured at
"Passenger Source Sense" will
decrease to slightly less than "Ignition 1" voltage. When
the voltage measured at
"Passenger Source Sense" is
within a specified range of "Ignition 1" for 500
milliseconds DTC 3S is set.
DTC WILL SET WHEN
The voltage measured at "Passenger Source Sense"
terminal "AS" is within a specified range of "Ignition 1" for
500 milliseconds. This test is run every 100 milliseconds
during "Continuous Monitoring" tests.
ACTION TAKEN
DERM turns "ON" the "AIR BAG" warning lamp and sets
diagnostic trouble code.
DTC WILL CLEAR WHEN
The voltage measured at "Passenger Source Sense"
terminal "AS" is outside the specified range of "Ignition 1"
which sets the diagnostic trouble code, for 500
milliseconds.
DTC CHART TEST DESCRIPTION
Number(s) below refer to step number(s) on the
diagnostic chart.
2. This test checks for an open in the "Passenger 3S
VLR" circuit.
3. This test determines whether the malfunction is due
to high resistance
in the "Passenger Source Sense"
circuit.
4. This test checks for a short from the
"Passenger
Source Sense"
circuit to B+.
5. This test determines whether the malfunction is due
to a malfunction within the dual pole arming sensor.
DIAGNOSTIC AIDS
An intermittent condition is likely to be caused by a poor
connection at dual pole arming sensor terminal
"1" or "5",
poor connection at DERM terminal "A3" or" AS", an open
in CKT 1813 or CKT 1814 or an open inside the dual pole
arming sensor.
