DIAGNOSIS CODES CHECK

CAUTION

Turn off the ignition switch before connecting or
disconnecting the M.U.T.-III.
Connect the M.U.T.-III to the diagnosis connector
(16-pin) under the instrument under cover, then
check diagnosis codes (Refer to GROUP 00, Diag-
nosis Function ).

ERASING DIAGNOSIS CODE
