Repair procedures

Inspection
1.

Switch "OFF" ignition.

2.

Remove the air cleaner.

(Refer to Engine Mechanical System - "Air cleaner")

3.

Disconnect the main connector (A).

4.

Measure the resistance between ground terminal (10) and signal terminal (9).

Specification : 3.5 ± 0.2 Ω

Removal
1.

Remove the valve body assembly.

(Refer to Hydraulic System - "Valve Body")

2.

Disconnect the solenoid valve connector.

3.

Remove the line pressure control solenoid valve (A) after removing the support bracket by loosening a bolt (B).

Tightening torque :

9.8 - 11.8 N·m (1.0 - 1.2 kgf·m, 7.2 - 8.7 lb·ft)

Installation
1.

Install in the reverse order of removal.

  

Perform the procedures below after installing.

1)

Clear the diagnostic trouble codes (DTC) using the KDS/GDS. Disconnecting the battery negative terminal will not clear the DTCs. Clear DTCs using the KDS/GDS at all times.

2)

Reset the automatic transaxle adaptive values using the KDS/GDS.

3)

Perform the TCM adaptive values learning procedure.

(Refer to Automatic Transaxle Control System - "Adjustment")
