Select: 501.00 Body System
e.
Select: Deployment control 0 resistance.
f.
Select: Deployment control 1 resistance.
5.
Check the resistance values are within the
specified limits (listed below).
6.
Perform a dynamic test by observing the
resistance values while rotating the steering wheel from
lock to lock. (No variation in resistance should be seen).
7.
If a variation in the resistance is seen, record the
steering position where the fault was present and the
resistance value.
8.
Remove the airbag in accordance with the
relevant workshop manual.
9.
Check the airbag connections
