DTC B2205 VEHICLE SPEED CIRCUIT

Description

INFOID:0000000004219278

The brake ECU provides a vehicle speed signal to the hybrid vehicle control ECU via CAN communication

lines. The hybrid vehicle control ECU then sends the vehicle speed signal to the combination meter via CAN

communication lines.

DTC Logic

INFOID:0000000004219279

Diagnosis Procedure

INFOID:0000000004219280

Symptom: Displays “VEHICLE SPEED CIRC [B2205]” as a self-diagnosis result of combination meter.

1.

CHECK COMBINATION METER INPUT SIGNAL

1. Start engine and select “METER/M&A” on CONSULT-III.

2. Using “SPEED METER” on “DATA MONITOR”, compare the value of DATA MONITOR with speedometer

pointer of combination meter.

Are the speedometer and DATA MONITOR indications close?

YES

>> Perform brake ECU self-diagnosis. Refer to 

BRC-45, "CONSULT-III Function"

.

NO

>> Replace combination meter. Refer to 

MWI-135, "Removal and Installation"

.

COMBINATION METER : Diagnosis Procedure

INFOID:0000000004219281

1.

CHECK FUSES

Check for blown combination meter fuses.

Are any combination meter fuses blown?

YES

>> Eliminate cause of malfunction before installing new fuse.

NO

>> GO TO 2

2.

POWER SUPPLY CIRCUIT CHECK

1. Disconnect combination meter connector.

2. Check voltage between combination meter harness connector

M24 terminals 1, 2, 14 and ground.

Do test results match chart?

YES

>> GO TO 3

NO

>> Check harness for open between combination meter and fuse.

3.

GROUND CIRCUIT CHECK

1. Turn ignition switch OFF.

2. Check continuity between combination meter harness connector

terminals 3, 4, 23 and ground.

Do test results match chart?

YES

>> Inspection End.

NO

>> Check ground harness.

BCM (BODY CONTROL MODULE) : Diagnosis Procedure

INFOID:0000000004499266

1.

 CHECK FUSE AND FUSIBLE LINK

Check if the following BCM fuse or fusible link are blown.

Is the fuse or fusible link blown?

YES

>> Replace the blown fuse or fusible link after repairing the affected circuit.

NO

>> GO TO 2

2.

 CHECK POWER SUPPLY CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect BCM.

3. Check voltage between BCM harness connector and ground.

Is the measurement normal?

YES

>> GO TO 3

NO

>> Repair or replace harness.

3.

 CHECK GROUND CIRCUIT

Check continuity between BCM harness connector and ground.

Does continuity exist?

YES

>> Inspection End.

NO

>> Repair or replace harness.
