2. Turn the ignition switch ON (ll), and check that the SRS indi-
cator light comes on for about six seconds and goes off
Ch6ck for a Short to another wile or decreased resistance in
the dummy resistor:
1. Turn the ignitaon switch OFF.
2. Remove the dummy resistor from the SRS main harness
2P connector.

3. Check the resistance between the A and B terminals of
the dummy resistor. There should be 1-5 - 2.5 O.
Check for a short to another wile or decrea36d r6istance in
the SRS main harness:
1. Disconnect the battery negative cable, then d'sconnect
the positive cable, and wait for three m inutes

3. Disconnect the SRS main harness 18P connector from
the sRs unit.
NOTE: Do not connect the dummy resistor to the SRS
main harness 2P connector.
4. Check resistance between the No lO terrninal andNo lil
terminal of the SRS main harness 18P connector' There
should be 1 M0 or more.
