Check 7.5 A fuse No. 11 for efficiency. With inter-
face wiring disconnected from the control unit,
check the continuity of the blue - black cable be-
tween pressure sensor connector and the horn
remote control base as indicated in the photo-
graph. Check the continuity between pin 27 and
the remote control base white cable.
Check the continuity of the yellow - red cable be-
tween the pressure switch connector and the fuse-
box and between the remote control base and the
fuse-box.
With a multimeter, also check the pressure switch
operation as well as the continuity at rest as this is
normally closed switch.
