The SRS lndicator Stays On When ln "SCS"
Menu Method
NOTE:. lf you cannot retrieve DTCSwith the PGM Tester
using the SRS menu method. retrieve the flash codeswith the Tester in SCS mode {see page 23-24|,.. A new SRS unit must sense the entire system is OK
before completing its initial self-test. The most
common cause of an incomplete self-test is the
failure to replace all deployed parts after a collision,
in particular, seat belt tensioners and seat belt buckletenstoners.. An incomplete self-test prevents the PGM Tester fromretrieving DTCS, although flash codes are available in
the Tester's SCS mode.
1 . Erase the DTC memory using the MES connector(see page 23-26).
Does the SRS indicator go off while you are
erasing the DTC memory?
YES-Go to step 42.

Connect the cable reel to the driver's airbag 4P
connector (A), then installthe access panel (B) on
the steering wheel.
Connect the battery negative cable.
After installing the airbag, confirm proper system
operation:
. Turn the ignition switch ON (ll); the SRS indicator
should come on for about 6 seconds and then go
off.. Make sure the horn works.
