P0890 TCM

DTC Description

INFOID:0000000010622836

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connector [TCM power supply (back-up) circuit is open or shorted]
• TCM

FAIL-SAFE

• Selector shock is large
• Start  is  slow
• Acceleration is slow
• Lock-up is not performed
• Vehicle speed is not increased
• 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 and wait for 5 seconds or more.

2.

Check the DTC.

NO-1

>> To check malfunction symptom before repair: Refer to 

GI-44, "Intermittent Incident"

.

NO-2

>> Confirmation after repair: INSPECTION END

Diagnosis Procedure

INFOID:0000000010622837

1.

CHECK TCM POWER SUPPLY (BACK-UP) CIRCUIT

1.

Turn ignition switch OFF.
