SRS

Symptom Troubleshooting (cont’d)

NOTE:

• If you cannot retrieve DTCs with the HDS using the

SRS menu method, retrieve the flash codes with the
Tester in SCS mode (see page 23-36).

• 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.

• An incomplete self-test prevents the HDS from

retrieving DTCs, although flash codes are available in
the Tester’s SCS mode.

1. Erase the DTC memory by ‘‘SCS’’ menu method

(see page 23-38).

Go to step 37.

Go to step 2.

2. Check the No. 2 (10A) fuse in the driver’s under-

dash fuse/relay box.

Go to step 17.

Go to step 3.

3. Replace the No. 2 (10A) fuse in the driver’s under-

dash fuse/relay box.

4. Turn the ignition switch ON (II) and wait for 30

seconds. Then turn the ignition switch OFF.

5. Check the No. 2 (10A) fuse in the driver’s under-

dash fuse/relay box.

The system is OK at this time.

Go to step 6.

6. Replace the No. 2 (10A) fuse in the driver’s under-

dash fuse/relay box.

7. Turn the ignition switch OFF. Disconnect the

battery negative cable, and wait for 3 minutes.

8. Disconnect the driver’s airbag connector (A), front

passenger’s airbag connector (B), and both seat
belt tensioner 2P connectors (C).

Does the SRS indicator go of f while the DT C
memor y is er ased?

Is the f use OK ?
