Check the SRS indicetor circuit input voltage:1. Reconnect the SRS main harness l8P connector to theSRS unit.2. Connect a voltmeter between the No. 1 terminal (+) ofthe dashboard 5P connector and ground.3. Turn the ignition switch ON (ll), wait for six seconds,then measure voltage,
ls th€re 8.5 V or more?
YESNO
The problem has disapp€ared due to di3connecting andconneding the connectors. Be su.e all te.minals makegood contact, and recheck the system {see T.ouble-shooting Inte.miftent Failures on page 24-15).
