Check fuses FIO and F14 in LH engine bay fuse box; if blown determine reason for rupture and
renew.
Check wiring harness continuity from multi
-plug 26-way connector pin 24 to relay unit
connector pin
6 and column switchgear connector pin 16. Ensure secure ground connection
from column switchgear connector pin
7.
Check wiring harness continuity from fuse connector pins 7 and 8 to LH and RH horn
respectively. Ensure secure ground connection from both horn units.
Ensure that
+12V (nominal) is present at the relay connector pin.
Operate horn switches and check that
+12V (nominal) is present at the two fuse connector pins
and
at speaker connector pin 44 (both units).
Check resistance across speaker unit pins;
a value of approximately 2Q should be recorded.
