Honda airbag trouble codes.

To Read SRS Codes

  1. Make sure the ignition switch is OFF. Wait at least 10 seconds after turning the ignition switch to OFF; this is important.

  2. Locate the 16P Data Link Connector (a.k.a. OBD II connector).  is mounted in the driver’s. You do not have to remove any covers to get to this connector.

  3. Jumper pins 4 and 9 of the Data Link Connector. See below.

  4. Turn the ignition switch ON (II). The SRS indicator light comes on for about 6 seconds (performing a “bulb check”) and then goes off. Then the light will flash the code.

  5. Watch the light, counting flashes and estimating their duration, and read the code.
