NOTE:* l: In case of an intermittent failure DTC g-1, it means there was an internal failure of the SRS unit or a faultv SRS indicator light circuit. Do the troubleshooting for intermittent failures (see page 24-15).*2: lt both DTC 9-2 and DTC 5-1 are indicated, do the troubleshooting for DTC g-2.*3: Apply to the '97 model coupe HX and DX.*4: DTC cannot be read with a Honda PGM Tester; check by jumping the SCS service connector.
