DTC A1-1x ("x" can be 0 thru 9 or A thru F); Faulty Power Supply (VA Line)
- Check the No. 10 (7.5 A) fuse in the under-dash fuse/relay box.
Is the fuse OK?
YES -Go to step 2.
NO -Replace the fuse, then turn the ignition switch ON (II). If the fuse blows again, check for a short in the No. 10 (7.5 A) fuse circuit (dashboard wire harness, floor wire harness, or OPDS/ODS unit harness).
- Disconnect the negative cable from the battery, then wait for 3 minutes.
- Disconnect SRS unit connector A (28P) from the SRS unit (see step 7 ).
- Reconnect the negative cable to the battery.
- Connect a voltmeter between the No. 17 terminal of SRS unit connector A (28P) and body ground. Turn the ignition switch ON (II), and measure the voltage. There should be battery voltage.

Is there battery voltage?
YES -Faulty SRS unit or poor connection at SRS unit connector A (28P) and the SRS unit; check the connection. If the connection is OK, replace the SRS unit (see SRS UNIT REPLACEMENT ).
NO -Go to step 6.
- Turn the ignition switch OFF.
- Disconnect under-dash fuse/relay box connector S (2P).
- Measure the resistance between the No. 1 terminal of under-dash fuse/relay box connector S (2P) and the No. 17 terminal of SRS unit connector A (28P). There should be 0-1.0 Ω.Fig 3: Measuring Resistance Between Under-Dash Fuse/Relay Box Connector S (2P) And SRS Unit Connector A (28P) Terminals

Is the resistance as specified?
YES -Open in the under-dash fuse/relay box or poor contact between connector S (2P) and the under-dash fuse/relay box; check the connection. If the connection is OK, replace the under-dash fuse/ relay box (see REMOVAL AND INSTALLATION ).
NO -Open in the dashboard wire harness; replace the dashboard wire harness.
