Replace multi-
function display.
CAUTION:
Make sure that a short-circuit does not

INSPECTION
1. Insert the thin electric conductors

(lead)
into the speed sensor coupler
2
, as
shown, and connect the tester to them.
CAUTION:
• Do not insert the electric conductors
more than required because it may
reduce the waterproof function of the
coupler.
• Make sure that a short-circuit does not
develop between the terminals because it
may cause damage to electrical compo-
nents.
2. Set the main switch to “ON”.
