Turn Signal/Hazard Relay Input Test
SRS components are located in this area. Review theSRS component /ocations, precautions, ano proceoures
in the SRS section (24) before performing repairs or ser-vice.
1.Remove the turn signal/hazard relay from the under-dash fuse/relay box.
Inspect the relay and luselrelay box socket terminals
to be sure they are all making good contact.
lf the terminals are bent, loose or corroded,reparr them as necessary, and recheck the system.lf the terminals look OK, make the following
input tests at the fuse/relay box socket.- lf any test indicates a problem, find and cor-
rect the cause, then recheck the system.- lf all the input tests prove OK, the turn signal/
hazard relay must be faulty; replace it.
