Inspection
Driver Airbag (DAB) |
Never attempt to measure the circuit resistance of the airbag
module (squib) even if you are using the specified tester. If the circuit
resistance is measured with a tester, accidental airbag deployment will
result in serious personal injury.
|
1. |
Check pad cover for dents, cracks or deformities.
|
2. |
Check the airbag module for denting, cracking or deformation.
|
3. |
Check hooks and connectors for damage, terminals for deformities,
and harness for binds.
|
4. |
Check airbag inflator case for dents, cracks or deformities.
|
5. |
Install the airbag module to the steering wheel to check for fit
or alignment with the wheel.
|
1. |
If, as a result of the following checks, even one abnormal point
is discovered, replace the clock spring with a new one.
|
2. |
Check connectors and protective tube for damage, and terminals
for deformities.
|
Installation
1. |
Remove the ignition key from the vehicle.
|
2. |
Disconnect the battery negative cable from battery and wait for
at least three minutes before beginning work.
|
3. |
Connect the clock spring harness connector to the clock spring.
|
4. |
Install the steering column shroud.
|
5. |
Set the center position by setting the marks between the clock
spring and the cover into line. Make an array the mark (▶◀) by turning
the clock spring clockwise to the stop and then 3.0 revolutions counterclockwise.
|
6. |
Install the steering wheel. (Refer to the Steering System group-
Steering Column and Shaft)
|
7. |
Connect the driver airbag (DAB) module connector, and then install
the driver airbag (DAB) module on the steering wheel.
