U0115-901

U0115-901

Description

INFOID:0000000004212175

The hybrid vehicle control ECU transmits and receives signals to and from the ECM through CAN communica-

tion line. When the ECM sends the same P-RUN signal to the hybrid vehicle control ECU for 2 seconds, the

hybrid vehicle control ECU will set a DTC U0115-901.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC confirmation procedure has been previously conducted, always turn ignition switch OFF and wait at

least 10 seconds before conducting the next test.

If DTC U0115-901 is displayed with DTC P0A1D-924 or P0A1D-925, first perform the diagnosis procedure for

P0A1D-924, P0A1D-925.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

1. Turn ignition switch ON and wait at least 3 seconds.

2. Check DTC.
Is DTC detected?

YES

>> Go to 

HBC-580, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000004212177

1.

PRECONDITIONING

• Before inspecting the high-voltage system or disconnecting the low voltage connector of the inverter with

converter assembly, take safety precautions such as wearing insulated gloves and removing the service

plug grip to prevent electrical shocks. After removing the service plug grip, put it in your pocket to prevent

other technicians from accidentally reconnecting it while you are working on the high-voltage system.

• After disconnecting the service plug grip, wait for at least 10 minutes before touching any of the high-voltage

connectors or terminals.

• Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with

converter assembly.

>> GO TO 2.

2.

CHECK HARNESS CONTINUITY BETWEEN HYBRID VEHICLE CONTROL ECU AND ECM

Refer to 

LAN-4, "Description"

.

OK or NG

OK

>> GO TO 3.

NG

>> Repair or replace harness or connectors.

3.

CHECK DTC OUTPUT (ENGINE)

1. Turn ignition switch ON.

2. Check DTC for engine control system.
Is DTC detected?

DTC No.
