driving at a speed greater than 48 mph
(80 km/h).
No
Does the volume change?
Yes
The fault has been rectified. Check the signal on
connection 47F (see wiring
diagrams Technical Note,
vehicle, code 261) using a
multimeter. The voltage should
vary depending on vehicle
speed. Reset the control to: CURVE 2.
