CHECK CIRCUIT BETWEEN TCM AND ELECTRIC OIL PUMP RELAY (PART 1)

1.

Disconnect the TCM connector.

2.

Check continuity between TCM harness connector terminal and electric oil pump relay harness connector
terminal.
NOTE:
• A diode is located between TCM and the electric oil pump relay.
• To check diode, refer to 

TM-592, "Component Inspection (Diode)"

.

Is the inspection result normal?

YES 

>> GO TO 4.

NO

>> Repair or replace malfunctioning parts.

4.

CHECK CIRCUIT BETWEEN TCM AND ELECTRIC OIL PUMP RELAY (PART 2)

Check continuity between the electric oil pump relay harness connector terminal and ground.

Is the inspection result normal?

YES 

>> GO TO 5.

NO

>> Repair or replace malfunctioning parts.

5.

CHECK ELECTRIC OIL PUMP RELAY SIGNAL

1.

Install the electric oil pump relay.

2.

Connect the TCM connector.

3.

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

Is the inspection result normal?

YES 

>> Check intermittent incident. Refer to 

GI-41, "Intermittent Incident"

.

NO

>> Replace TCM. Refer to
