CAUTION:
Be sure to perform AIR BAG DIAGNOSTIC SYSTEM CHECK before starting diagnosis according to
flow table.
When measurement of resistance or voltage is required in this table, use a tester along with a cor-
rect terminal adapter from special tool (Connector test adapter kit).
When a check for proper connection is required, refer to INTERMITTENT AND POOR CONNEC-
TIONS in this section.
If there is open circuit in the air bag wire harness, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.

10B-48 AIR BAG SYSTEM
TABLE TEST DESCRIPTION
STEP 1 : This test rechecks “AIR BAG” warning lamp operation.
STEP 2 : This test rechecks whether an abnormality is in SDM.
DTC B1061 :
DTC B1071 – Internal SDM Fault
DTC WILL SET WHEN
An internal SDM fault is detected by SDM.
DTC B1013 – System Specifications Different from SDM Specifications
DTC WILL SET WHEN
Specifications of the air bag system differ from those of SDM.Step Action Yes No
1 1) This DTC is set when there is a trouble in
“AIR BAG” warning lamp circuit. Failure to
properly perform AIR BAG DIAGNOSTIC
SYSTEM CHECK may also result in mis-
diagnosis. Therefore, check “AIR BAG”
warning lamp circuit again according to
AIR BAG DIAGNOSTIC SYSTEM
CHECK.
Is “AIR BAG” warning lamp circuit in good
condition?Go to step 2. Repair “AIR BAG” warning
lamp circuit.
2 1) Clear DTC (Refer to DTC CLEARANCE).
2) Check DTC (Refer to DTC CHECK).
Is DTC B1061 set?Substitute a known-
good SDM and recheck.Recheck air bag system.

Handling and storage
SDM
•Never attempt disassembly of SDM.
•When storing SDM, select a place where neither high tem-
perature nor high humidity is anticipated and oil, water and
dust are kept off.
•If SDM has been dropped, replace it with a new one.
•If installation part of SDM was damaged, repair that part
completely before reinstallation.
•All SDM and mounting bracket fasteners must be carefully
torqued and the arrow must be pointed toward the front of
the vehicle to ensure proper operation of the air bag system.
WARNING:
Never power up air bag system when SDM is not rigidly
attached to the vehicle. Otherwise, personal injury may
result.
CAUTION:
After detecting one time of such collision as to meet
deployment conditions, the SDM must not be used. Refer
to “AIR BAG DIAGNOSTIC SYSTEM CHECK” when
checking the SDM.

10B-56 AIR BAG SYSTEM
Repairs and Inspections Required after an Accident
Accident with deployment/activation - component replacement
Certain air bag system components must be replaced. Those components are:
•Driver and passenger air bag (inflator) modules
–Replace with new one.
•Driver and Passenger seat belt pretensioners
–Replace with new one.
•SDM after detecting such collision as to meet deployment conditions
–Replace with new one.
•Forward sensors
–Replace with new one. CAUTION:
All air bag system components, including the electrical harness (component mounting points),
must be inspected after an accident. If any components are damaged or bent, they must be replaced
even if air bag system activation did not occur.
Never use air bag system parts from another vehicle.
Do not attempt to service the parts below. Service of these parts is by replacement only.
–Driver/Passenger air bag (inflator) modules, Driver/Passenger seat belt pretensioners
–Forward sensors
–SDM
–Contact coil and combination switch assembly
–Air bag wire harness
Proper operation of the sensors and air bag system requires that any repairs to the vehicle struc-
ture return it to its original production configuration.
CAUTION:
After detecting one time of such collision as to meet deployment conditions, the SDM must not be
used.
Refer to “AIR BAG DIAGNOSTIC SYSTEM CHECK” when checking the SDM.

AIR BAG SYSTEM 10B-57
Accident with or without deployment/activation - component inspections
Certain air bag and restraint system components must be inspected after any crash, whether the air bag system
activated or not.
Those components are:
•Steering column and shaft joints
–Check for length, damage and bend according to “CHECK-
ING STEERING COLUMN FOR ACCIDENT DAMAGE” in
Section 3C1.
•Steering column bracket and capsules
–Check for damage and bent.
•If any faulty condition is found in above checks, replace faulty
part.
•Steering wheel and driver air bag (inflator) module
–Check for damage or air bag (inflator) module fitness.
–Check trim cover (pad surface) for cracks.
–Check wire harness and connector for damage or tightness.
•If any faulty condition is found in above checks, replace faulty
part.
•Contact coil and combination switch assembly
–Check wire harness and connectors for damage or tight-
ness.
–Check contact coil case for damage.
•If any faulty condition is found in above checks, replace.
