Code No.32, 36 Shift Control Solenoid Valve System

SOLENOID VALVE SYSTEM CIRCUIT

 Refer to 

P.23A-77

.

OPERATION

The shift control solenoid valve controls the CVT 
gear ratio by using the signal from the 
engine-CVT-ECU.

DIAGNOSIS CODE SET CONDITIONS

• If the shift control solenoid valve driving voltage is 

3 V or less, code No.32 will be set.

• If the primary pressure is approximately 0.5 MPa 

or less when code No.32 is set, code No.36 will 
be set.

PROBABLE CAUSES

• Malfunction of shift control solenoid valve

• Damaged harness wires and connectors

• Malfunction of the engine-CVT-ECU

DIAGNOSIS PROCEDURE

STEP 1. M.U.T.-III diagnosis code

Q: Are diagnosis codes 34, 38 set?

YES : 

Go to Step 9.

NO : 

Go to Step 2.

STEP 2. M.U.T.-III actuator test
Item 02: Shift control solenoid valve

OK: Operating sound can be heard.

Q: Is the check result normal?

YES : 

Intermittent malfunction (Refer to GROUP 

00 

− How to Cope with Intermittent 

Malfunction 

P.00-13

).

NO : 

Go to Step 3.

STEP 3. Connector check: A-117 CVT control 
solenoid valve assembly connector.

20

°C)

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Replace the valve body assembly. (Refer to 

P.23A-155

).
