1 1) With ignition switch OFF, disconnect contact coil con-
nector located near the base of the steering column.
2) Check proper connection to contact coil at terminals
in “Q06” connector.
3) If OK then connect Special Tool (B) to contact coil
connector disconnected at step 1).
With ignition switch ON, is DTC B1025 current?Go to step 2. Go to step 3.
2 1) With ignition switch OFF, disconnect Special Tool (B)
and SDM connector.
2) Measure voltage from “Q01-9” terminal to body
ground and from “Q01-10” terminal to body ground.
With ignition switch ON, are they 1 V or less?Substitute a known-
good SDM and
recheck.Repair short from
“GRN” or “GRN/RED”
wire circuit to power
circuit.
3 1) With ignition switch OFF, disconnect Special Tool (B)
then reconnect contact coil connector located near
the base of the steering column.
2) Remove driver air bag (inflator) module from steering
wheel (Refer to DRIVER AIR BAG (INFLATOR)
MODULE in Section 3C1).
3) Check proper connection to driver air bag (inflator)
module at terminals in “Q05” connector.
4) If OK then connect Special Tool (B) to “Q05” connec-
tor.
With ignition switch ON, is DTC B1025 current?Ignition switch OFF.
Replace contact coil
assembly (Refer to
COMBINATION
SWITCH/CON-
TACT COIL AND
COMBINATION
SWITCH ASSEM-
BLY in Section
3C1).Ignition switch OFF.
Replace driver air
bag (inflator) module
(Refer to DRIVER
AIR BAG (INFLA-
TOR) MODULE in
Section 3C1).
NOTE:
Upon completion of inspection and repair work, perform following items.
Reconnect all air bag system components, ensure all components are properly mounted.
Clear diagnostic trouble codes (Refer to DTC CLEARANCE), if any.
Repeat AIR BAG DIAGNOSTIC SYSTEM CHECK to confirm that the trouble has been corrected.

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.

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-
