M.U.T.-III sub assembly
A: Vehicle communication
interface (V.C.I.)
B: M.U.T.-III USB cable
C: M.U.T.-III main harness
A (Vehicles with CAN
communication system)
D: M.U.T.-III main harness
B (Vehicles without CAN
communication system)
E: M.U.T.-III measurement
adapter
F: M.U.T.-III trigger harness
• Drive belt tension check
• Checking the ignition timing
• Checking the idle speed
CAUTION
If you connect M.U.T.-III main
harness A to a vehicle without
CAN communication system to
use the M.U.T.-III, a pulse signal
may interfere with the
simulated vehicle speed lines,
thus causing the M.U.T.-III
inoperative. Therefore, use the
M.U.T.-III main harness B
(MB991911) instead.
