DOOR MIRROR SWITCH ASSEMBLY
(CONTROL SWITCH, FOLDING
SWITCH
AND DEFOGGER SWITCH)
(FIG. 8-305)
The door mirror switch is made up of the control
switch that controls the vertical and horizontal move­
ment of both mirrors, the folding switch, and the
defogger switch.
The control switch consists of six switches, two of
which are used to select a mirror on either the left or
the right side, and the remaining four switches control
vertical or horizontal mirror movement.
The folding switch contains two switches, and their
contacts are changed over each time these switches
are depressed. The direction of the current flow to the
motor in the mirror is controlled to perform the fold­
ing and returning action of the mirror.
When depressing the defogger switch, the defogger
indicator lights up to inform the driver that the mirror
built-in heater is operating.

9J-76 Supplemental Restraint System
DTC34
DUAL POLE ARMING SENSOR IGNITION FEED OPEN
CIRCUIT DESCRIPTION
During the "turn-ON" tests, performed at the beginning
of each ignition cycle, the DERM delays the charging of
the
"Driver 36 VLR" and "Passenger 36 VLR" power
supplies.
While the delay is active the DERM measures
the voltage at the "Driver VLR" terminal "A4" ,
"Passenger 36 VLR" terminal "A3", "Driver Source
sense" terminal "AS", and "Passenger Source Sense"
terminal "A6". When the voltage measured at the two "36
VLR" power supplies indicates they are in a discharged
state and the voltage measured at each
"Source Sense"
terminal is a specified amount below "Ignition 1" voltage
DTC34 is set.
DTC WILL SET WHEN
With both "36 VLR" power supplies in a discharged state,
the voltage measured at "Driver
Source Sense" terminal
"AS" and "Passenger Source Sense" terminal "A6" are
simultaneously a specified amount below
"Ignition 1"
voltage and no "higher priority faults" are detected. This
test is run once each ignition cycle during the "Turn-ON"
tests while the "36
VLR Delay" is active.
ACTION TAKEN
DERM turns "ON" the AIR BAG" warning lamp and sets
a diagnostic trouble code.
DTC WILL CLEAR WHEN
With both "36 VLR" power supplies in a discharged state,
the voltage measured at specified range of
"Ignition 1"
voltage. When
neither the failure nor clear conditions are met, the
state of the diagnostic trouble code from the previous
ignition cycle is used.
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 "Ignition 1" circuit
between the
splice and the dual pole arming sensor.
3. This test determines whether the malfunction is
internal to the dual pole arming sensor.
4. This test checks for an open in fuse C-24.
s. This test checks for a short from CKT 1809 to ground.
DIAGNOSTIC AIDS
An intermittent condition is likely to be caused by an
improper connection at dual pole arming sensor terminal
"3" or "6" and "7" improper connection at DERM terminal
"AS" or "A6", open ignition feed to the dual pole arming
sensor, open "Driver
Source Sense" circuit and open
"Passenger
Source Sense" circuit, or malfunctioning
dual pole arming sensor ignition diodes. The test for this
diagnostic trouble code is only run while the "AIR
BAG"warning lamp is performing the bulb check. When
a scan tool "Clear Code" command is issued and the
malfunction
is still present, the DTC will not reappear
until the ignition switch is turned
"OFP' for at least two
minutes with the entire
SRS connected and then the
ignition switch is turned
"ON."

9J-84 Supplemental Restraint System
DTC42
LOOP ENERGY RESERVE VOLTAGE LOW
CIRCUIT DESCRIPTION
During the "Turn-ON" tests, performed at the beginning
of each ignition
cycle, the DERM delays charging of the
"Driver "36
VLR" terminal "A4" and "Passenger 36 VLR"
terminal
"A3" power supplies. After delay has expired
both "36
VLR" power supplies are allowed to change.
The DERM monitors each
"36 VLR" power supply to
ensure each has changed to a
voltage above a specified
value within 1 0 seconds after "Ignition 1" voltage is first
applied to DERM. When either "36 VLR" power supply
does not reach the specified voltage within the allowed
time or, once reaching the voltage, falls it for 500
milliseconds, DTC 42 is set.
DTC WILL SET WHEN
The voltage at either "36 VLR" power supply does not
exceed a specified
value within 10 seconds after "Ignition
1" voltage is first applied to the DERM or once having
reached the specified
value, either "36 VLR" power
supply voltage falls below the specified value for 500
milliseconds.
This test is run each ignition cycle at
"Turn-ON" to detect a change time failure and, after
charging, tested every
100 milliseconds during the
"Continuous Monitoring" tests.
ACTION TAKEN
DERM turns "on" the "AIR BAG" warning lamp and sets
a diagnostic
trouble code.
DTC WILL CLEAR WHEN
The voltages measured at "Driver 36 VLR" terminal "A4"
and "Passenger 36
VLR" terminal "A3" are above a
specified
value for 500 milliseconds.
DTC CHART TEST DESCRIPTION
Number(s) below refer to step number(s) on the
diagnostic chart.
2. This test checks whether the DERM has set the
diagnostic
trouble code falsely.
3. This test checks whether a malfunctioning dual pole
arming sensor is preventing dual pole arming sensor
is preventing the "Driver 36
VLR" or "Passenger 36
VLR" from charging.
4. This test checks for a short from the "Driver 36 VLR"
or "Passenger 36 VLR" circuit to 8+.
5. This test checks for a short from the "Driver 36 VLR"
or "Passenger 36 VLR" circuit to ground.
DIAGNOSTIC AIDS
An intermittent condition is likely to be caused by a short
from "Driver 36
VLR" or "Passenger 36 VLR" to B+ or
ground, or a short inside the
dual pole arming sensor.

DRIVER IGNITION DIODE OPEN
CIRCUIT DESCRIPTION
During the "Turn-ON" tests, performed at the beginning
of each ignition
cycle, the DERM delays the charging of
the "Driver
3S VLR" and "Passenger 3S VLR" power
supplies. While the delay is active the DERM measures
the
voltage at the "Driver 3S VLR" terminal "A3", "Driver
Source
Sense" terminal "AS", and "Passenger Source
Sense" terminal "AS". When the voltage measured at the
two
"3S VLR" power supplies indicates they are in a
discharged state, the
voltage measured at "Passenger
Source
Sense" is within a specified range of "Ignition 1"
voltage
measured at "Driver Source Sense" is a specified
amount
below "Ignition 1" voltage DTC 81 is set.
DTC WILL SET WHEN
With both "3S VLR" power supplies in a discharged state,
the DERM detects
"Ignition 1" voltage at "Passenger
Source
Sense" terminal "AS" while simultaneously the
DERM detects
"Ignition 1" voltage at "Driver Source
Sense" terminal "AS". This test is run once each ignition
cycle during the "Turn-ON" tests while the "3S VLR
Delay"
is active.
ACTION TAKEN
DERM turns "ON" the "AIR BAG" warning lamp and sets
a diagnostic
trouble code.
DTC CHART TEST DESCRIPTION
Number(s) below refer to step number(s) on the
diagnostic chart.
2. This test checks for a short from the "Driver Source
Sense" circuit to the "Passenger 3S VLR" circuit.
3. This test checks for a short from the "Driver Source
Sense"circuit to the "Driver
3S VLR" circuit.
4. This test determines whether the malfunction is due
to open within the
dual pole arming sensor.
DIAGNOSTIC AIDS
An intermittent condition is likely to be caused by a short
between
CKT 1811 CKTIB12, a short between CKT 1811
and CKT 1813 or an open inside the dual pole arming
sensor. The test for this diagnostic
trouble code is only
run while the check. When a scan tool "Clear Codes"
command is issued and the malfunction is still present,
the
DTC will not reappear until the ignition switch is
turned
"OFF" for at least two minutes with the entire SRS
connected and then the ignition switch is turned "ON."
