DATA LIST / ACTIVE TEST
1. DATA LIST
HINT:
According to the DATA LIST displayed by the OBD II scan tool or hand-held tester, you can read the value
of the switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as the first step of
troubleshooting is one method to shorten labor time.
(a) Warm up the engine.
(b) Turn the ignition switch off.
(c) Connect the OBD II scan tool or hand-held tester to the DLC3.
(d) Turn the ignition switch to the ON position.
(e) Push the "ON" button of the OBD II scan tool or the hand-held tester.
(f) When you use the hand-held tester:
Select the item "DIAGNOSIS / ENHANCED OBD II / DATA LIST".
(g) According to the display on the tester, read the "DATA LIST".

2. ACTIVE TEST
HINT:
Performing the ACTIVE TEST using the hand-held tester allows the relay, VSV, actuator and so on to oper-
ate without parts removal. Performing the ACTIVE TEST as the first step of troubleshooting is one method
to shorten labor time.
It is possible to display the DATA LIST during the ACTIVE TEST.
(a) Warm up the engine.
(b) Turn the ignition switch off.
(c) Connect the hand-held tester to the DLC3.
(d) Turn the ignition switch to the ON position.
(e) Turn on the tester.
(f) Select the item "DIAGNOSIS / ENHANCED OBD II / ACTIVE TEST".
(g) According to the display on the tester, perform the "ACTIVE TEST".

[Test Details]
Operate the shift solenoid valve and set each shift position by yourself.
[Vehicle Condition]
Possible to check the operation of
SHIFT Less than 50 km/h (31 mph)
the shift solenoid valves.

S Press "" button: Shift up
S Press "" button: Shift down

Control the shift solenoid SLU to set the automatic transmission to the
lock-up condition. Possible to check the SLU opera-

[Vehicle Condition] tion.
S Throttle valve opening angle: Less than 35 %
S Vehicle Speed: 60 km/h (37 mph) or more
[Test Details]
Operate the shift solenoid SLT and raise the line pressure.
[Vehicle Condition]
S Vehicle Stopped.
S IDL: ON
LINE PRESS UP * -
[HINT]
OFF: Line pressure up (When the active test of "Control the Line Pres-
sure Up" is performed, the ECM commands the SLT solenoid to turn
off).
ON: No action (normal operation)
*: "LINE PRESS UP" in the ACTIVE TEST is performed to check the line pressure changes by connecting
the SST to the automatic transaxle, which is used in the HYDRAULIC TEST (See page DI-958) as well.
HINT:
The pressure values in ACTIVE TEST and HYDRAULIC TEST are different from each other.
