DTC P1722 ESTM VEHICLE SPEED SIGNAL
Revision: June 20062007 Versa
DTC P1722 ESTM VEHICLE SPEED SIGNALPFP:47660
DescriptionUCS0062P
The vehicle speed signal is transmitted from ABS actuator and electric unit (control unit) to TCM by CAN com-
munication line.
CONSULT-II Reference ValueUCS0062Q
Remarks: Specification data are reference values.
On Board Diagnosis LogicUCS0062R

This is not an OBD-II self-diagnostic item.

Diagnostic trouble code “P1722 ESTM VEH SPD SIG” with CONSULT-II is detected when TCM does not
receive the proper vehicle speed signal (input by CAN communication) from ABS actuator and electric
unit (control unit).
Possible CauseUCS0062S

Harness or connectors
(Sensor circuit is open or shorted.)

ABS actuator and electric unit (control unit)
DTC Confirmation ProcedureUCS0062T
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to con-
firm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “TRANSMISSION” with
CONSULT-II.
3. Start engine and maintain the following conditions for at least 5
consecutive seconds.
ACC PEDAL OPEN: 1.0/8 or less
VEHICLE SPEED SE: 30 km/h (17 MPH) or more
4. If DTC is detected, go to CVT-153, "
Diagnostic Procedure" .

UNIFIED METER CONTROL UNIT

Speedometer, odo/trip meter, tachometer and fuel gauge are controlled by the unified meter control unit,
which is built into the combination meter.

Warning and indicator lamps are controlled by signals drawn from the CAN communication system, BCM
(body control module), and components connected directly to the combination meter.

Odo/trip meter and A/T indicator (with A/T) or CVT indicator (with CVT) segments can be checked in self-
diagnosis mode.

Meters/gauges can be checked in self-diagnosis mode.
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times

through 10A fuse [No. 13, located in the fuse block (J/B)]

to combination meter terminal 27.
With the ignition switch in the ON or START position, power is supplied

through 10A fuse [No. 14, located in the fuse block (J/B)]

to combination meter terminal 28.
Ground is supplied

to combination meter terminals 21, 22 and 23

through grounds M57 and M61.
SPEEDOMETER
With ABS
The ABS actuator and electric unit (control unit) provides a vehicle speed signal to the combination meter via
CAN communication lines.
Without ABS or CVT
The vehicle speed sensor provides a vehicle speed signal to the combination meter for speedometer indica-
tion.
With CVT, Without ABS
The TCM provides a vehicle speed signal to the combination meter via CAN communication lines.
TACHOMETER
The tachometer indicates engine speed in revolutions per minute (rpm). The ECM provides an engine speed
signal to combination meter via CAN communication lines.
FUEL GAUGE
The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by the unified meter control unit and a variable resistor signal supplied

to combination meter terminal 24

through fuel level sensor unit and fuel pump terminal 5

through fuel level sensor unit and fuel pump terminal 2

from combination meter terminal 6.
ODO/TRIP METER
The vehicle speed signal and the memory signals from the meter memory circuit are processed by the combi-
nation meter and the mileage is displayed.
How to Change the Display
Refer to Owner's Manual for odo/trip meter operating instructions.
CAN COMMUNICATION SYSTEM DESCRIPTION
