Examine fuse F1 in right hand 'A' post base fusebox, if blown determine reason for rupture and
renew.
Check continuity of harness wiring as shown on Fig.
1 below. Ensure secure ground connection
from lock/ unlock and deadlock (not N.A.S.) relay pins
4 and 9.
Remove the left hand rear seat hell board, gaining access to lock/ unlock and deadlock (not
N.A.S.) relays. Operate lock/ unlock and deadlock checking for audible relay operation. renew
suspect relays.
Release door lock and measure resistance between actuator unit pins
2 and 3, a value of
approximately
8Q should be recorded. Operate door lock and check that circuit between pins 2
and 3 is opened. Resistance across pins 1 and 3 should now be approximately 88.

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.
