(b) Inspect light warning buzzer function
(1) Disassemble combination instrument.
(2) Connect battery positive wire to terminal A5 and nega-
tive to terminal A1 and A2.
(3) Connect battery positive wire to terminal A18 and nega-
tive to terminalA17,inspect buzzer.
Audio buzzer: long buzzes
(4) When buzzer works, connect battery positive wire to ter-
minal A4,inspect whether buzzer stop working.

together, only key buzzer works.
(1) Insert the key, when driver seat door opens, turn ignition
switch to OFF (LOCK or ACC). inspect key buzzer works
1HZ discontinuously.
(b) inspect key buzzer function
(1) Disassemble combination instrument.
(2) Connect battery positive wire to terminal A5 and nega-
tive to terminal A1 and A2.
(3) Connect battery negative wire to terminal A17 and B8,
inspect buzzer which should work discontinuously.
(4) When buzzer works, connect battery positive wire to ter-
minal A4,inspect whether buzzer stop working.
