DTC P1721 VEHICLE SPEED SENSOR MTR
Revision: 2007 April2007 M35/M45
DTC P1721 VEHICLE SPEED SENSOR MTRPFP:24814
DescriptionNCS001MN
The vehicle speed sensor·MTR signal is transmitted from combination meter to TCM by CAN communication
line. The signal functions as an auxiliary device to the revolution sensor when it is malfunctioning. The TCM
will then use the vehicle speed sensor·MTR signal.
CONSULT-II Reference ValueNCS001MO
On Board Diagnosis LogicNCS001MP

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

Diagnostic trouble code “P1721 VHE SPD SE/CIR-MTR” with CONSULT-II is detected when TCM does
not receive the proper vehicle speed sensor MTR signal (input by CAN communication) from unified
meter and A/C amp.
Possible CauseNCS001MQ
Harness or connectors
(Sensor circuit is open or shorted.)
DTC Confirmation ProcedureNCS001MR
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, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “ECU INPUT SIGNALS” in “DATA MONITOR” mode for
“A/T” with CONSULT-II.
3. Touch “START”.
4. Start engine and maintain the following conditions for at least 5
consecutive seconds.
ACCELE POSI: 1.0/8 or less
VHCL/S SE-MTR: 30 km/h (17 MPH) or more
5. If DTC is detected, go to AT- 1 4 1 , "
Diagnostic Procedure" .
Item name Condition Display value
VHCL/S SE-MTR During driving Approximately matches the speedometer reading.

Self-diagnosis FunctionNJS000GJ
DESCRIPTION
The self-diagnosis system diagnoses sensors, door motors, blower motor, etc. by system line. Refer to appli-
cable sections (items) for details. Shifting from normal control to the self-diagnosis system is accomplished by
starting the engine (turning the ignition switch ON) and pressing OFF switch for at least 5 seconds. The OFF
switch must be pressed within 10 seconds after starting the engine (ignition switch is turned ON). This system
will be canceled by either pressing AUTO switch or turning the ignition switch OFF. Shifting from one step is
accomplished by means of pressing temperature control switch (driver side), as required.
Shifting from STEP-5 to AUXILIARY MECHANISM is accomplished by means of pressing (fan) UP switch.

AUXILIARY MECHANISM: TEMPERATURE SETTING TRIMMER
The trimmer compensates for differences in range of ±3°C (±6°F) between temperature setting (displayed dig-
itally) and temperature felt by customer.
Operating procedures for this trimmer are as follows:
1. Begin self-diagnosis STEP-5 mode. Refer to AT C - 5 6 , "
Self-diagnosis Function" .
2. Press (fan) UP switch to set system in auxiliary mode.
3. Display shows “61” in auxiliary mechanism. It takes approximately 3 seconds to enable setting operation.
4. Press temperature control switch (driver side) as desired. Temperature will change at a rate of 0.5°C
(1.0°F) each time a switch is pressed.
CAUTION:
A decimal point is not indicated on the display.
When battery cable is disconnected or battery voltage is below 10 V, trimmer operation is canceled. Tempera-
ture set becomes that of initial condition, i.e. 0°C (0°F).

When the TEL voice and voice guidance is output, it controls the
volume of each speaker.
BOSE 2ch System
It receives the TEL voice signal from AV (NAVI) control unit and out-
put it to the BOSE amp.
BOSE Surround 5.1ch System

It receives the TEL voice signal from AV (NAVI) control unit and
output it to the BOSE amp.

DVD player receives the received AUX sound and the downmix
sound of DVD player, and then sends them to the BOSE amp.
BOSE AMP
BOSE 2ch System

It amplifies the sound signal from the audio unit and output it to
each speaker.

It receives the voice guidance signal from AV (NAVI) control unit
and output it to the front speaker.

It controls sound volume of each speaker when outputting TEL
voice and voice guidance.

It subjects to AudioPilot® processing when receiving sound sig-
nal from microphone for AudioPilot
