2) Place a 100
:
resistance on the harness
connector terminal using a suitable lead wire,
and connect to ground through the resistance.
Connector & terminal
(i84) No. 10 — Chassis ground:
Does the security indicator light
illuminate? Check body inte-
grated unit. <Ref.
to LAN(diag)-2,
Basic Diagnostic
Procedure.> Go to step 2 .
2 CHECK POWER SUPPLY FOR SECURITY

nation meter.
2) Measure the voltage between the combina-
tion meter harness connector terminal and
chassis ground.
Connector & terminal

Is the voltage 10 V or more? Go to step 3 . Check the harness
for open or short
circuits between
combination meter
and fuse.
3 CHECK SECURITY INDICATOR LIGHT CIR-
CUIT.
Measure the resistance between the combina-
tion meter harness connector terminal and the
