DATA LIST / ACTIVE TEST

1. READ DATA LIST

HINT:

Using the intelligent tester's DATA LIST allows switch, sensor, actuator, and other item values to be read without removing any parts. Reading the DATA LIST early in troubleshooting is one way to save time.

NOTICE:

In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

(a) Warm up the engine.

(b) Turn the ignition switch OFF.

(d) Turn the ignition switch ON.

(e) Turn the intelligent tester ON.

(f) Enter the following menus: DIAGNOSIS / OBD/MOBD / ECT / DATA LIST.

(g) Follow the instructions on the tester and read the DATA LIST.

2. PERFORM ACTIVE TEST

HINT:

Performing the intelligent tester's ACTIVE TEST allows relay, VSV, actuator and other items to be operated without removing any parts. Performing the ACTIVE TEST early in troubleshooting is one way to save time.

The DATA LIST can be displayed during the ACTIVE TEST.

(a) Warm up the engine.

(b) Turn the ignition switch OFF.

(d) Turn the ignition switch ON.

(e) Turn the tester ON.

(f) Enter the following menus: DIAGNOSIS / OBD/MOBD / ECT / ACTIVE TEST.

(g) Perform the ACTIVE TEST.

Test Part

Control Range

Diagnostic Note

LINE PRESS UP*

Operate the shift solenoid SLT and raise line pressure

ON or OFF

HINT:

OFF: Line pressure up (when Active Test "LINE PRESS UP" is performed, ECM commands SLT solenoid to turn OFF)
ON: No action (normal operation)

[Vehicle Condition]

Vehicle stopped
Engine: idling

LOCK UP

Control shift solenoid SLU to set automatic transmission to lock-up condition

ON or OFF

Possible to check shift solenoid valve SLU operation

[Vehicle Condition]

Throttle valve opening angle: Less than 35%
Vehicle speed: 60 km/h (36 mph) or more

SHIFT

Operate shift solenoid valve and set each shift position by yourself

Press "→" button: Shift up
Press "←" button: Shift down

Possible to check operation of shift solenoid valves

[Vehicle Condition]

50 km/h (30 mph) or less

HINT:

*: LINE PRESS UP in the ACTIVE TEST is performed to check the line pressure changes by connecting SST to the automatic transmission, which is used in the HYDRAULIC TEST as well. Please note that the pressure values in the ACTIVE TEST and HYDRAULIC TEST are different.
