Code No.34: Overdrive solenoid valve system

SOLENOID VALVE SYSTEM CIRCUIT
Refer to

P.23A-65

.

OPERATION

•

Solenoid valve closes or opens according to the
signals from the engine-A/T-ECU.

•

The engine-A/T-ECU energizes or deenergizes
solenoid valve, based on input signals such as
throttle position sensor opening angle, inhibitor
switch, etc.

diagnosis code set conditions
If the drive terminal voltage of the overdrive solenoid
valve is 3.0 V or less, it is judged that there is a short
circuit or open circuit in the overdrive solenoid valve,
and diagnosis code 34 is output.
If diagnosis code 34 is output 4 times, the
transmission is fixed in 3rd as a fail-safe measure.

Possible causes

•

Malfunction of overdrive solenoid valve

•

Damaged harness wires and connectors

•

Malfunction of the engine-A/T-ECU

DIAGNOSIS

STEP 1. MUT-II/III diagnosis code

Q: Are diagnosis codes 32 and 33 set?

YES :

Go to Step 9.

NO :

Go to Step 2.

STEP 2. MUT-II/III actuator test

Item 04: Overdrive solenoid valve

OK: Operating sound can be heard.

Q: Is the check result normal?

YES :

Intermittent malfunction (Refer to GROUP

00

−

Malfunction

P.00-6

.)

NO :

Go to Step 3.

STEP 3. Connector check: B-34 A/T control
solenoid valve assembly connector

Check for the contact with terminals.

Q: Is the check result normal?

YES :

Go to Step 4.

NO :

Repair the defective connector.

STEP 4. Measure the resistance at A/T control
solenoid valve assembly connector B-34.

Disconnect the connector, and measure the
resistance between terminal No.5 and No.9 at the
solenoid valve side.

Q: Is the check result normal?

YES :

Go to Step 5.

NO :

Check the overdrive solenoid valve and
solenoid valve harness.

STEP 5. Measure the voltage at engine-A/T-ECU
connector C-138.
(1) Connect A/T control solenoid valve assembly

connector B-34.
