VEHICLE SPEED SIGNAL
DescriptionINFOID:0000000005928210
The vehicle speed signal is built into the speedometer assembly. The sensor functions as an auxiliary device
to the output speed sensor when it is malfunctioning. The TCM will then use a signal sent from the vehicle
speed signal.
CONSULT-III Reference Val ue in Data Monitor ModeINFOID:0000000005928211
Remarks: Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000005928212
• This is not an OBD-II self-diagnostic item.
• Diagnostic trouble code “VEHECLE SPEED SIGNAL” with CONSULT-III or 2nd judgement flicker without
CONSULT-III is detected when TCM does not rece ive the proper voltage signal from the sensor.
Possible CauseINFOID:0000000005928213
• Harness or connector
(The sensor circuit is open or shorted.)
• Vehicle speed signal
DTC Confirmation ProcedureINFOID:0000000005928214
CAUTION:
• Always drive vehicle at a safe speed.
• If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait at
least 10 seconds before continuing.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON and select “DATA MO NITOR” mode for “TRANSMISSION” with CONSULT-III.
2. Touch “START”.
3. Start engine and accelerate vehicle from 0 to 25 km/h (0 to 16 MPH).
4. If the check result is NG, go to AT-155, "
Diagnosis Procedure" .
WITHOUT CONSULT-III
1. Start engine.
2. Drive vehicle under the following conditions:
Selector lever posi tion: “D” position
Vehicle speed: Higher than 25 km/h (16 MPH)
3. Perform self-diagnosis. Refer to AT-82, "
Diagnosis Procedure without CONSULT-III" .
4. If the check result is NG, go to AT-155, "
