INFOID:0000000005260374

Diagnosis Procedure

INFOID:0000000005260375

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. Speedometer and DATA MONITOR indications should be close.

Is the inspection result normal?

YES

>> Perform ABS actuator and electric unit (control unit) self-diagnosis. Refer to 

BRC-22, "CONSULT-

III Function (ABS)"

.

NO

>> Replace combination meter. Refer to 

MWI-96, "Removal and Installation"

.
