YES 

>> GO TO 2.

NO

>> Repair or replace malfunctioning parts.

2.

CHECK CIRCUIT BETWEEN TCM AND CVT UNIT (PART 2)

Check continuity between TCM harness connector terminals and ground.

Is the inspection result normal?

YES 

>> GO TO 3.

NO

>> Repair or replace malfunctioning parts.

3.

CHECK TCM INPUT SIGNALS

1. Connect all connectors removed. 

2. Start the engine.

3. Check voltage between TCM harness connector terminal and ground. 

Is the inspection result normal?

YES >> Check 

intermittent incident. Refer to 

GI-41, "Intermittent Incident"

.

NO

>> There is malfunction of secondary pressure sensor. Replace transaxle assembly. Refer to

DTC CONFIRMATION PROCEDURE

1.

PREPARATION BEFORE WORK

If another "DTC CONFIRMATION PROCEDURE" occurs just before, the ignition switch OFF and wait for at

least 10 seconds, then perform the next test.

>> GO TO 2.

2.

CHECK DTC DETECTION

With CONSULT

1. Start the engine.

2. Select “Data Monitor” in “TRANSMISSION”.

3. Select “FLUID TEMP”.

4. Maintain the following conditions for 10 seconds or more.

5. Check the first trip DTC.

With GST

1. Start the engine and wait for at least 10 seconds.

CAUTION:

When the ambient temperature is 

20°C (4°F) or less and the engine is cold, warm up the engine

for approximately 5 minutes. 

2. Check the first trip DTC.
Is “P0848”detected?

YES

>> Go to 

TM-177, "Diagnosis Procedure"

.

NO

Diagnosis Procedure

INFOID:0000000009019710

1.

CHECK SECONDARY PRESSURE SENSOR POWER SUPPLY CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect CVT unit connector.

3. Turn ignition switch ON.

4. Check voltage between CVT unit harness connector terminal and ground.

Is the inspection result normal?
