Diagnostic Procedure
ATF(Automatic Transmission fluid) level Inspection
1.

Start the engine and allow it to reach normal operating temperature.

2.

Depress the brake pedal and move the shift lever slowly all ranges.

3.

Set shift lever in "P" position and check the ATF level.

9.

Engine "ON"

10.

Check TCC duty of the current data

11.

Perform actuation data of the torque converter clutch solenoid valve. (The purpose of actuation test is to check operating sound of TCC solenoid valve.)

A.

Specification : if TCC operating sound could be heard, Solenoid valve is OK.
