NOTE:*1: In case of an intermittent failure DTC g-1, it means there was an internal failure of the SRS unit or a faulw SRS indica-tor light circuit. Do the troubleshooting for intermittent failures (see page 2,+_2g),*2: In case of an intermiuent fairure DTc 9-2, it means there was an internar fairure of the power suppry (vB rine). Do thetroubleshooting for intermittent failures (see page 24-29).*3: DTC cannot be read with a Honda PGM Tester; check by jumping the SCS servic€ connector.
NOTE: Before troubleshooting DTCS 5-1 through g-6. check battery/system voltage. lf voltage is low, repair the charg_ing system before troubleshooting the SRS system.
