Engine-ECU or engine-CVT-ECU has
been provided with the following functions for easier
system inspection.FREEZE-FRAME DATA
When the engine-ECU or engine-CVT-ECU
detects a problem and stores the resulting
diagnosis code, the engine condition at that time is
also memorized. The M.U.T.-III can then be used to
analyze this data in order to increase the effective
-
ness of troubleshooting. The freeze-frame data dis-
play items are given below.

•RISE (Reinforced Impact Safety Evolution) has
been adopted for the main body in order to
ensure all-round impact safety at high level.
•The use range of rust-resistant steel plates has
been expanded and high strength steel plates
have been optimally arranged. In addition,
rust-resistant steel plates are adopted for items
such as the hood, doors, inner panels of tailgate,
and reinforcements in order to improve the rust
resistance of the main body and to reduce its
weight.
•Sealer has been applied to the entire folded area
of the flanges for the doors, hood, and tailgate in
order to improve rust resistance.

NOTE: *: If a diagnosis code is sent for this function,
the display informs users whether a mechanical
problem currently exists or whether it existed before
but normal operation has been restored. The mes

sage for the former state identifies it as active trouble
and the message for the latter identifies it as stored
trouble.
