2002 mitsubishi montero door chime not working

A HOnda Mitsubishi? huh?
MITSU: sport or non sport?
for some its a blessing, vast posts world wide to on how to kill em.
but is:
first in all electric fails check all dash and engine bay fuses.
ETACS ECU , is the controller, on this car.
Electric Time & Alarm Control System
1: does the chim work on all other chime active errors? , like the KEY reminder feature? if that works , id bet the ETACS is ok.

2: the door switch bad (drivers?) the door switch is like #1 fail on all cars. they get dirty , fail to close, (rust) and bingo bad switch.
the way to diagnose it it is to use the FSM book.
the door switch ground the Door ajar pin in ETACS,
so if the voltage on the wire is not at 0v door closed, the switch is
bad, or the ground wire to it is rusted and bad.

the operators guide is free, get it, and read it, and see all things
that make the chime sound. can be many things. ETACS has a large number of inputs..
