TOR

CAUTION:

• Do not rotate the roll connector to more than

the  specified  number  of  turns.  Otherwise,  the

roll connector internal wire may be broken.

• When  determining  the  end  stop,  rotate  the

connector  slowly  without  applying  excessive

force. Applying excessive force at the end stop

may break the internal wire.

Test harness N (98299SA000)

Test harness Q (98299SA040)

Airbag module connector (black) — Test harness

(1N)

Airbag module connector (orange) — Test harness

(1Q)

4) With  the  following  conditions,  check  the  resis-

tance  between  the  test  harness  connector  termi-

nals.

• Perform  the  check  with  the  roll  connector  cen-

tered (front wheels direct straightforward).

• Rotate the roll connector counterclockwise from

the  center  (front  wheels  direct  straightforward)  to

an end stop. Then, perform the check while rotating

it clockwise to approximately 3.25 turns.
Preparation tool: Circuit tester

NOTE:

Terminals are designed to be shorted as the con-

nection between airbag main harness and roll con-

nector is disconnected.

5) Replace the roll connector with a new part if the

inspection result is not within the standard value.
