P188E ELECTRIC OIL PUMP

DTC Description

INFOID:0000000010646394

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connector (Open circuit or short circuit in harness between the TCM and the electric oil pump)
• Electric oil pump
• Electric oil pump relay
• TCM

FAIL-SAFE

• Restart the engine during the stop/start system operation
• Turn OFF the electric oil pump relay
• When the vehicle is in stop/start system operation and the engine stops, restart the engine immediately

DTC CONFIRMATION PROCEDURE

CAUTION:

Be careful of the driving speed.

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

With CONSULT

1.

Start the engine.

TM-635, "Component Inspection (Electric Oil Pump Relay)"

.

Is the inspection result normal?

YES 

>> GO TO 2.

NO

>> Replace the electric oil pump relay.

2.

CHECK ELECTRIC OIL PUMP RELAY POWER CIRCUIT

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

Is the inspection result normal?

YES 

>> GO TO 3.

NO

>> GO TO 8.

3.

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-635, "Component Inspection (Diode)"

.

Is the inspection result normal?

YES 

>> GO TO 4.

NO

>> Repair or replace malfunctioning parts.
