TROUBLE DIAGNOSIS

Diagnostic Procedure Without CONSULT-IIBCS0010E
TCM SELF-DIAGNOSTIC PROCEDURE (WITHOUT CONSULT-II)
Description
If a malfunction occurs in electrical system, check the self-diagnostic result after confirming A/T CHECK indi-
cator lamp works. To detect a malfunction, entering a self-diagnosis start signal retrieves information on mal-
functions from memory and indicates malfunction by blinking A/T CHECK indicator lamp.
Diagnostic Procedure
1. CHECK A/T CHECK INDICATOR LAMP
1. Park vehicle on flat surface.
2. Move selector lever to “P” position.
Start engine and warm it up to normal engine operating temperature.
3. Turn ignition switch OFF.
4. Wait 5 seconds.
5. Turn ignition switch ON. (Do not start engine.)
Does A/T CHECK indicator lamp come on for about 2 seconds?
YES >> GO TO 2.
NO >> Stop procedure. Perform AT- 1 7 3 , "
A/T CHECK Indicator Lamp Does Not Come On" before pro-
ceeding.
2. JUDGEMENT PROCEDURE STEP 1
1. Turn ignition switch OFF.
2. Push and hold shift lock release button.
3. Depress the brake pedal, then move gear selector lever from “P” to “3” position.
4. Turn ignition switch ON. (Do not start engine.)
5. Wait 3seconds.
6. Move selector lever to “2” position.
7. Release brake pedal.
8. Move selector lever to “1” position.
9. Depress brake pedal.
10. Depress accelerator.
11. The A/T CHECK indicator lamp will begin to flash.
>> GO TO 3.
3. CHECK SELF-DIAGNOSTIC CODE
Check A/T CHECK indicator lamp. Refer to AT- 7 7 , "
Judgement of Self-Diagnosis Code" .

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.)

Lamp turns off.
PNP switch, 3rd position switch, stop lamp switch, closed throttle
position signal or wide open throttle position signal circuit is dis-

(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
DTC Confirmation ProcedureBCS0010J
CAUTION:

Always drive vehicle at a safe speed.

Be careful not to rev engine into the red zone on the tachometer.

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-II
1. Turn ignition switch ON and select “DATA MONITOR” mode for
“A/T” with CONSULT-II.
2. Drive vehicle and check for an increase of “VHCL/S SE-MTR”
value.
If the check result is NG, go to AT- 8 8 , "
Diagnostic Procedure" .
If the check result is OK, go to following step.
3. Select “DATA MONITOR” mode for “A/T” with CONSULT-II.
4. Start engine and maintain the following conditions for at least 5
consecutive seconds.
VEHICLE SPEED: 30 km/h (19 MPH) or more
THROTTLE POSI: More than 1.0/8
SLCT LVR POSI: “D” position
Driving location: Driving the vehicle uphill (increased engine load) will help maintain the driving
conditions required for this test.
If the check result is NG, go to AT- 8 3 , "
Diagnostic Procedure" .
If the check result is OK, go to following step.
5. Maintain the following conditions for at least 5 consecutive seconds.
ENGINE SPEED: 3,500 rpm or more
THROTTLE POSI: More than 1.0/8
SLCT LVR POSI: “D” position
Driving location: Driving the vehicle uphill (increased engine load) will help maintain the driving
conditions required for this test.
6. If DTC is detected, go to AT- 8 3 , "
Diagnostic Procedure" .
Item name Condition Display value
