General Note
1. If there is more than one malfunction, the code
numbers will be displayed on the tester one by one
in a numerical order. In the case of malfunctions,
55, 06, and 63, the code numbers are displayed
in an order of 06, 55, then 63. The display is as
shown.

2. The hold indicator flashes to indicate the same pat-
tern as the buzzer of the EC-AT Tester when the
EC-AT service connector is grounded.
When the EC-AT service connector is not ground-
ed, the indicator flashes in a constant frequency
while a malfunction is occurring and goes out
if
the
malfunction recovers. However, the warning code
is memorized in the EC-AT control unit.

Fail-safe program Proces--\Out sing -v puts
The EC-AT control unit has a built-in fail-safe func-
tion for the throttle sensor, the pulse generator, and
the 1-2, 2-3, and 3-4 shift solenoid valves.
If a malfunction occurs, the EC-AT control unit will
control operation of the remaining components ac-
cording to a preset fail-safe program.
The vehicle may still be driven, although the driv-
ing performance will be slightly affected.

4. The memory of warning codes is canceled by dis-
connecting the negative battery terminal for ap-
prox. five seconds.

2. Remove the EC-AT tester if it is connected.
3. Drive the vehicle at 50 km/h (31 mph), then de-
