Should I hear a beep? Silence is what I hear....
Hello
I have checked handbooks, RAVE too but could not find an answer to my question: should I hear a beep for things like seatbelt not on, or more importantly, lights left on buzzer? A chime for my 3 Amigos? I am hearing nothing, and honestly, the lights on buzzer would be helpful as I already ran down my battery once.
Assuming I am missing the sound, could anyone tell me how to fix? Is it a particular fuse?
Thanks

In the RAVE electrical manual:
The lights on alarm in the instrument pack operates when the driver's door is open and the
side lamps are on. The system uses inputs from:

OPERATION
Lights On Alarm Supply
Circuit supply
A feed from the battery positive terminal is connected on an R wire to the engine
compartment fusebox where it is connected to fusible links 8 and 12 and fuse 13.
A feed from fusible link 12 is connected on an NG wire to the lighting switch.
A feed from fuse 13 is connected on a PN wire to pin C0660-13 on the BCU. A BCU system
earth is provided by a B wire connected to earth header C0551.
A feed from fusible link 8 is connected on an NW wire to the passenger compartment
fusebox and from the fusebox to the ignition switch on an N wire.

A feed from fusible link 8 is connected on an NW wire to the passenger compartment

Ignition switch supply
With the ignition switch in position II, the feed from fusible link 8 flows through the ignition
switch to the passenger compartment fusebox on a Y wire. The feed continues through fuse
29 in the passenger compartment fusebox and is connected to pin C0660-1 on the BCU by
a GU wire.

Lights On Alarm Operation
When the lighting switch is moved to the side lamp or the headlamp position, the feed from
fusible link 12 passes through the lighting switch contacts and is connected to the passenger
compartment fusebox on an R wire.
The feed passes to the Intelligent Driver's Module (IDM), which is integral with the
passenger compartment fusebox. This feed is used as a 'side lights on' signal by the logic
circuits in the IDM and BCU.

The feed passes to the Intelligent Driver's Module (IDM), which is integral with the

circuits in the IDM and BCU.
The IDM is connected on the serial data bus link to pin C0661-1 on the BCU, and to the
instrument pack via header C0293 LHD/C0292 RHD by an SK wire. When the driver's door
is opened, the door switch contacts close, current flows from fuse 13 on a PN wire to pin
C0660-13 on the BCU. From pin C0660-17 on the BCU the current flows on a PW wire via
header C0287 LHD/C0285 RHD to the closed contacts of the drivers door switch. From the
closed contacts of the drivers door switch the current flows on a B wire through splice joint
A34 to earth header C0017 LHD/C0018 RHD (also via header C0288 on LH drive vehicles).
The current flow from fuse 13 is used by the logic signals of the BCU to generate a door open
output. The BCU communicates along the serial data bus with the IDM and the Instrument
pack.
The two 'door open' and 'lights on' signals generate the appropriate 'lights on' alarm output
to the instrument pack. The sounder in the instrument pack emits the lights on signal, and is
earthed via the instrument pack.
For the system logic to generate a lights on alarm signal both the 'door open' and 'lights on'
inputs must be present. If the light switch is turned off, the 'sidelights on' signal is removed.
With the loss of the input to the system the lights on alarm signal is cancelled by the logic
circuits. If the door is closed when the side lights are on, the logic circuits will also cancel the lights on alarm.instrument pack via header C0293 LHD/C0292 RHD by an SK wire. When the driver's door

Thank you for highlighting the relevant piece in RAVE; would you think a replacement of fuses would work or is it just as likely to be a problem somewhere in the entire process? Any suggestions where I might start troubleshooting?
