P1722 VEHICLE SPEED

Description

INFOID:0000000009650189

The vehicle speed signal is transmitted from ABS actuator and electric unit (control unit) to TCM via CAN com-
munication line.

DTC CONFIRMATION PROCEDURE

CAUTION:

Always drive vehicle at a safe speed.

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.

>> GO TO 2.

2.

CHECK DTC DETECTION

With CONSULT

1.

Start the engine.

2.

Drive the vehicle.

3.

Maintain the following conditions for 10 seconds or more.

4.

Stop the vehicle.

5.

Check DTC.

Is “P1722” detected?

YES

>> Go to 

TM-120, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000009650191

1.

CHECK DTC WITH ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT)

With CONSULT

1.

Turn ignition switch ON.

2.

Perform “Self Diagnostic Results” in “ABS”.

Is any DTC detected?

YES

>> Check DTC detected item. Refer to 

BRC-38, "DTC Index"

.

NO

>> Check intermittent incident. Refer to 

GI-42, "Intermittent Incident"

.

P1722

Vehicle Speed Signal Circuit

TCM detects malfunction in CAN communication 
with ABS actuator and electric unit (control unit)

• Harness or connectors

(CAN communication line is open 
or shorted.)

• ABS actuator and electric unit 

(control unit)

Vehicle speed signal received by TCM (via CAN 
communication) changes 17 km/h (11 MPH) or more 
in 0.1 second

When vehicle speed detected by TCM is 10 km/h (7 
MPH) or more, vehicle speed signal received by 
ABS actuator and electric unit (control unit) (CAN 
signal) is 2 km/h (1 MPH) or less

Vehicle speed

: 10 km/h (7 MPH) or more
