REDUNDANT SRS INDICATOR CIRCUIT FAIL RE
CIRCUIT DESCRIPTION
When the ignition switch is first turned "ON" battery
voltage is applied to the
"AIR BAG" warning lamp and to
the
"Ignition 1" input terminals "A9" and "A10". The
DERM responds by flashing the
"AIR BAG" warning lamp
seven
times alternating between the primary and
redundant lamp drivers. The DERM monitors the
redundant lamp driver output by comparing the output
state at "SRS Indicator" terminal "B1" to the
microprocessor commanded state. When
"lgnition1" is
above a specified value and the output state does not
match the commanded state of the redundant lamp
driver for
400 milliseconds DTC 62 is set.
DTC WILL SET WHEN
"Ignition 1" voltage is above a specified value and the
output state at the
"SRS Indicator'' terminal "B 1" does not
match the commanded state of the redundant lamp
driver for
400 milliseconds. This test is run every 100
milliseconds during "Continuous Monitoring" tests.
FUSE
ACTION TAKEN
DERM attempts to turn "ON" the "AIR BAG" warning
lamp using the primary lamp driver and sets a diagnostic
trouble code.
DTC WILL CLEAR WHEN
The ignition switch is turned "OFF."
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 "Redundant
Indicator Ground"
circuit.
3. This test determines whether the malfunction is due
to
an open in the "Redundant Indicator Ignition 1"
circuit.
DIAGNOSTIC AIDS
An intermittent condition is likely to be caused by a poor
connection to the DERM at terminal
"A2" or "B2", an open
in
CKT IY05 or an open in CKT IB03.

SERVICE PRECAUTIONS
CAUTION: WHEN PERFORMING SERVICE ON OR
AROUND SRS COMPONENTS OR SRS WIRING,
FOLLOW
THE PROCEDURES LISTED BELOW TO
TEMPORARILY
DISABLE THE SRS. FAILURE TO
FOLLOW PROCEDURES COULD RESULT IN
POSSIBLE AIR BAG DEPLOYMENT, PERSONAL
INJURY OR OTHERWISE UNNEEDED SRS
REPAIRS.
The DERM in Driver-Passenger SRS can maintain
sufficient voltage to cause a deployment for up to 2
minutes after the ignition switch is turned to
"OFF," the
battery is disconnected, or the fuse powering the DERM
is removed.
Many of the service procedures require removal of the
"AIR BAG" fuse, and disconnection of the inflator
modules from the deployment loop to avoid an accidental
deployment.
If the inflator module is disconnected from
the deployment loop as noted in the "Disabling the
SRS"
procedure that follows, service can begin immediately
without waiting for the 2 minute time period to expire.
DISABLING THE SRS
REMOVAL
• Turn the steering wheel so that the vehicle's wheels
are pointing straight ahead.
• Turn the ignition switch to "OFF"
1. Remove SRS fuse C-21, C-22, C-23 and C-24 from
left dash side lower fuse block.
2. Disconnect yellow
3-way connector at the base of
the steering column.
3. Remove
liP compartment door assembly, Refer to
"Passenger inflator module replacemenf' in section
9J-135.
4. Disconnect yellow 4-way connector behind the liP
compartment door assembly.
NOTE
• With the" AIR BAG" fuse removed and ignition switch
"ON," the "AiR BAG" warning lamp will be "ON." This
is normal operation and does not indicate
an SRS
malfunction.
ENABLING THE SRS
INSTALLATION
Turn ignition switch to "LOCK" and remove key.
1. Connect yellow 4-way connector of passenger
inflator module.
2. Install liP compartment door assembly, Refer to
"Passenger inflator module replacement" in section
9J-3.
3. Connect yellow 3-way connector at the base of the
steering column.
4. Install" AIR BAG" fuse C-21, C-22, C-23 and C-24 to
left dash side lower fuse block.
Tum ignition switch to
"RUN" and verify that the "AIR
BAG"
warning lamp flashes seven times and then turns
"OFF" If it does not operate as described, perform the
"SRS Diagnostic System Check" in section 9J-32.
HANDLING/INSTALLATION/DIAGNOSIS
1. Inflator modules should not be subjected to
temperatures above 65°C(150°F).
2. Discriminating s~nsors, inflator modules, arming
sensors, or DERMs should not be used if they have
been dropped from a height of 1
00 centimeters (3.28
feet) or more.
3. When a discriminating sensor or arming sensor is
replaced, it MUST be oriented with the arrow
on the
sensor pointing toward the front of the vehicle.
It is
very important for the discriminating sensors and
arming sensor to be located flat on the mounting
surface, parallel to the vehicle datum line.
It is
important that the sensor mounting surface is free of
any dirt or other foreign material.
4. Do not apply power to the SRS unless all
components are connected or a diagnostic chart
requests it, as this
will set a diagnostic trouble code.
5. The
"SRS Diagnostic System Check'' must be the
starting point of any SRS diagnostics. The
"SRS
Diagnostic System Check" will verify proper "AIR
BAG" warning lamp operation and will lead you to the
correct chart to diagnose any SRS malfunctions.
Bypassing these procedures may result in extended
diagnostic time, incorrect diagnosis, and incorrect
parts replacements.
INSPECTIONS REQUIRED AFTER ACCI­
DENT
CAUTION: CERTAIN SRS COMPONENTS MUST BE
REPLACED AFTER A FRONTAL
CRASH INVOLVING
AIR
BAG DEPLOYMENT.
In all types of accident regardless of "Air Bag"
deployment, visually inspect all the following
components and their points and replace as required:
- Passenger
Inflator Module
- Steering wheel
- SRS coil assembly
- Steering column
- Knee bolster and
Instrument panel mounting
