Code No.31: Low-reverse solenoid valve system

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 low-reverse
solenoid valve is 3.0 V or less, it is judged that there
is a short circuit or open circuit in the low-reverse
solenoid valve, and diagnosis code 31 is set.
If diagnosis code 31 is output 4 times, the
transmission is fixed in 3rd as a fail-safe measure.

Possible causes

•

Malfunction of low-reverse solenoid valve

•

Damaged harness wires and connectors

•

Malfunction of the engine-A/T-ECU

DIAGNOSIS

STEP 1. MUT-II/III diagnosis code

Q: Is diagnosis code 36 set?

YES :

Go to Step 9.

NO :

Go to Step 2.

STEP 2. MUT-II/III actuator test

Item 01: Low-reverse 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.00-6

.)

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.6 and No.10 at the
solenoid valve side.

OK: 2.7

Q: Is the check result normal?

YES :

Go to Step 5.

NO :

Check the low-reverse solenoid valve and
solenoid valve harness.
