From page
Check the SRS indicator light circuit:
1. Disconnect the dashboard wire harness 30P connector from
the gauge assembly.
2. Connect a voltmeter between the No. 15 terminal (+) of the
30P connector and ground.
3. Turn the ignition switch ON (II), and measure voltaqe.

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
).
Try to reproduce the SRS indicator light:
1. Erase the DTC memory (see page
).
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
).
).
Open or increased resistance in the driver's airbag infla-
tor; replace the driver's airbag (see page
).
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
2P connector. (cont'd)

the SRS main harness 18P connector.
There should be approx.
Poor contact at the SRS main harness 18P connector;
check the connector.
• If the connector is OK, substitute a known-good SRS
