DTC 1-1 and DTC 1-2

CAUTION: Whenever the ignition switch is ON (II), or
has been turned OFF for less than 3 minutes, be careful
not to bump the SRS unit; the airbags could accidentally
deploy and cause damage or injuries.

NOTE: The PCM memory must be reset after reconnect-
ing the battery (see page

11-125

Try to reproduce the SRS indicator light:

1. Erase the DTC memory (see page

24-37

2. Turn the ignition switch ON (II), and check that the SRS

indicator light comes on for about 6 seconds and then
goes off.

Does the SRS indicator light stay on?

Intermittent failure, system is OK at this time. See Trouble-
shooting Intermittent Failures on page

Check for an open in the driver's airbag inflator:

1. Turn the ignition switch OFF.

2. Disconnect the battery negative cable, then disconnect the

positive cable, and wait for 3 minutes.

3. Disconnect the driver's airbag 2P connector from the cable

reel 2P connector.

CAUTION: Do not disconnect the passenger's airbag con-
nector.

4. Connect the special tool to the cable reel 2P connec-

tor.

5. Reconnect the battery positive cable, then reconnect the

negative cable.

6. Erase the DTC memory (see page

24-37

7. Read the DTC (see page

24-35

Open or increased resistance in the driver's airbag infla-
tor; replace the driver's airbag (see page

24-160

Check for an open in the cable reel:

1. Disconnect the battery negative cable, then disconnect

the positive cable, and wait for 3 minutes.

2. Disconnect the special tool from the cable reel 2P

connector.

3. Remove the dashboard lower cover, and disconnect the

cable reel 2P connector from the SRS main harness.

4. Connect the special tool to the SRS main harness
