Honda Civic Service Manual page 1032

Including the most recent problem, up to three different DTCS can be indicated (see example 1 below).
ln case of a continuous failure, the DTC will be indicated repeatedly {see example 1 below).
In case of an intermittent failure, the SRS indicator will indicate the DTCS one time, then it will stay on (see example
2 below).
lf both a continuous and an intermittent failure occur, both DTCS will be indicated as continuous failures.
When the system is normal (no DTCS), the SRS indicator will stay on (see example 3).
lf the SRS indicator comes on continuously without a DTC, there mav be a problem with the svstem.
lf the SRS indicator does not come on as indicated above, always check for an open or a short to ground in the SCS
circuit before troubleshooting the system.
