P2815 SELECT SOLENOID

P2815 SELECT SOLENOID

DTC Description

INFOID:0000000010622854

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connector (Select solenoid valve circuit open or shorted to power supply)
• Select solenoid valve

FAIL-SAFE

• Selector shock is large
• Stop/start system prohibited
• Restart the engine during the stop/start system operation
• Turn OFF the electric oil pump relay

DTC CONFIRMATION PROCEDURE

1.

PREPARATION BEFORE WORK

If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn ignition switch OFF and wait for at
least 10 seconds, then perform the next test.

>> GO TO 2.

2.

CHECK DTC DETECTION

1.

Start the engine.

2.

Maintain the following conditions. (Keep 5 seconds or more after the selector lever shifted.)

3.

Check the first trip DTC.

Is “P2815” detected?

YES

>> Go to 

TM-650, "Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to 

GI-44, "Intermittent Incident"

.

NO-2

>> Confirmation after repair: INSPECTION END

Diagnosis Procedure

INFOID:0000000010622855

1.

CHECK CIRCUIT BETWEEN TCM AND CVT UNIT

1.

Turn ignition switch OFF.

2.

Disconnect TCM connector and CVT unit connector.

3.

Check continuity between TCM harness connector terminal and CVT unit harness connector terminal. 

Is the inspection result normal?

YES 

>> GO TO 2.

NO

>> Repair or replace damaged parts.

2.

CHECK SELECT SOLENOID VALVE CIRCUIT

When all of the following conditions are satisfied and this state is main-
tained for 0.2 seconds:
• TCM power supply voltage: More than 11 V
• TCM judges that solenoid valve circuit is open. 
• P2814 is not detected.

Diagnosis Procedure

INFOID:0000000010622856

1.

CHECK TCM POWER CIRCUIT (PART 1)

1.

Turn ignition switch OFF.

2.

Disconnect TCM connector.

3.

Check voltage between TCM harness connector terminals and ground.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> GO TO 4.

2.

CHECK TCM POWER CIRCUIT (PART 2)

Check voltage between TCM harness connector terminals and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> GO TO 5.

3.

CHECK TCM GROUND CIRCUIT

Check continuity between TCM harness connector terminals and ground.

Is the inspection result normal?

YES

>> Check intermittent incident. Refer to 

GI-44, "Intermittent Incident"

.

NO

>> Repair or replace malfunctioning parts.

4.

DETECT MALFUNCTION ITEMS (PART 1)

Check the following items:
• Open circuit or short circuit in harness between battery positive terminal and TCM connector terminal 45,

and 46. Refer to 

PG-12, "Wiring Diagram - BATTERY POWER SUPPLY -"

.

• 10A fuse [No.75, located in the fuse block (J/B)]. Refer to 

PG-84, "Fuse, Connector and Terminal Arrange-

ment"

.

Is the inspection result normal?

YES >> Check 

intermittent incident. Refer to 

GI-44, "Intermittent Incident"

.

NO

>> Repair or replace malfunctioning parts.
