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-386, "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

Diagnosis Procedure

INFOID:0000000010622575

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.49, located in the fuse and fusible link block). Refer to 

PG-86, "Fuse and Fusible Link Arrange-

ment"

.

Is the inspection result normal?

YES >> Check 

intermittent incident. Refer to 

GI-44, "Intermittent Incident"

.

NO

>> Repair or replace malfunctioning parts.
