SYSTEM DESCRIPTION
1. SYSTEM DESCRIPTION
(a) The Electronic Controlled Automatic Transaxle
(ECT) is an automatic transaxle that electronically
controls shift timing using the Engine Control
Module (ECM). The ECM detects electrical signals
that indicate engine and driving conditions, and
controls the shift point based on driver habits and
road conditions. As a result, fuel efficiency and
power transaxle performance are improved.
Shift shock is reduced by controlling the engine and
transaxle simultaneously.
In addition, the ECT has the following features:
• Diagnostic function.
• Fail-safe function when a malfunction occurs.

HOW TO PROCEED WITH
TROUBLESHOOTING
HINT:
• The ECM of this system is connected to the CAN and
multiplex communication system. Therefore, before
starting troubleshooting, make sure to check that there is
no trouble in the CAN and multiplex communication
systems.
• *: Use the intelligent tester.
