HOW TO ERASE SELF-DIAGNOSTIC RESULTS (WITHOUT CONSULT-II)
1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait for at least
5 seconds and then turn it ON again.
2. Perform AT- 7 6 , "
Diagnostic Procedure" .
3. Turn ignition switch OFF. (The self-diagnostic results will be erased.)
11th judgement flicker is longer than others.
Line pressure solenoid valve circuit is short-circuited or discon-
nected.

Go to AT-126, "
LINE PRESSURE SOLENOID VALVE" .12th judgement flicker is longer than others.

Lamp turns off.
PNP switch, 3rd position switch, stop lamp switch, closed throttle
position signal or wide open throttle position signal circuit is dis-
connected or TCM is damaged.
(Because 3rd position switch signal, stop lamp switch signal,
closed throttle position signal and wide open throttle position sig-
nal are input via CAN communication line malfunction may con-
tinue after self-diagnosis.)

VEHICLE SPEED SENSOR·A/T (REVOLUTION SENSOR)

VEHICLE SPEED SENSOR·A/T (REVOLUTION SENSOR)PFP:32702
DescriptionBCS0010F
The revolution sensor detects the revolution of the idler gear parking pawl lock gear and emits a pulse signal.
The pulse signal is sent to the TCM which converts it into vehicle speed.
CONSULT-II Reference ValueBCS0010G
On Board Diagnosis LogicBCS0010H
Diagnostic trouble code “VHCL SPEED SEN-A/T” with CONSULT-II or 1st judgement flicker without CON-
SULT-II is detected when TCM does not receive the proper voltage signal from the sensor.
Possible CauseBCS0010I

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

Revolution sensor
