DTC B2205 VEHICLE SPEED CIRCUIT
DescriptionINFOID:0000000005146075
The ABS actuator and electric unit (control unit) provi des a vehicle speed signal to the combination meter via
CAN communication lines.
DTC LogicINFOID:0000000005146076
Diagnosis ProcedureINFOID:0000000005146077
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 “M ETER/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 uni t (control unit) self-diagnosis. Refer to BRC-23, "CONSULT-
III Function (ABS)".
NO >> Replace combination meter. Refer to MWI-100, "
Removal and Installation".
DTC CONSULT-III display Detection condition
B2205 VEHICLE SPEED CIRC
[B2205]
Malfunction is detected when an erroneous speed signal is received for 2 seconds or more.

CAUTION:
Even when there is no ma
lfunction on CAN communication system, malfunction may be
misinterpreted when battery has low voltag e (when maintaining 7 - 8 V for about 2 sec-
onds) or 10A fuse [No. 3, located in the fuse block (J/B)] is disconnected. MWI-26
