CONSULT-II Function (A/T) BCS0010D
CONSULT-II can display each diagnostic item using the diagnostic test models shown following.
FUNCTION
NOTICE:
1. The CONSULT-II electrically displays shift timing and lock-up timing (that is, operation timing of each sole-
noid).
Check for time difference between actual shift timing and the CONSULT-II display. If the difference is
noticeable, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical
parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) displayed on CONSULT-II and that indicated in Service Man-
ual may differ slightly. This occurs because of the following reasons:
–Actual shift schedule has more or less tolerance or allowance,
–Shift schedule indicated in Service Manual refers to the point where shifts start, and
–Gear position displayed on CONSULT-II indicates the point where shifts are completed.
3. Shift solenoid valve “A” or “B” is displayed on CONSULT-II at the start of shifting. Gear position is dis-
played upon completion of shifting (which is computed by TCM).

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" .

or EC-427, "
SELF-DIAG RESULTS MODE" (VQ engine).
NO >> GO TO 2.
2. SYMPTOM CHECK
Check again. Refer to AT- 5 0 , "
Cruise Test — Part 1" .
OK or NG
OK >>INSPECTION END
NG >> GO TO 3.
3. CHECK TCM
1. Check TCM input/output signals. Refer to AT- 6 4 , "
TCM Terminals and Reference Value" .
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.
OK or NG
OK >>INSPECTION END
NG >> Repair or replace damaged parts.
Engine Speed Does Not Return To Idle (Light Braking D4 → D3 )BCS0014N
SYMPTOM:
Engine speed does not smoothly return to idle when A/T shifts from D4 to D3 on “Cruise Test — Part
1”.
DIAGNOSTIC PROCEDURE
1. CHECK SELF-DIAGNOSTIC RESULTS
Perform self-diagnosis. Refer to AT- 6 9 , "
SELF-DIAGNOSTIC RESULT MODE" or AT- 7 6 , "Diagnostic Proce-
dure Without CONSULT-II" .
Is any malfunction detected by self-diagnostic results?
YES >> Check the malfunctioning systems. Refer to AT- 6 9 , "SELF-DIAGNOSTIC RESULT MODE" or AT-
77, "Judgement of Self-Diagnosis Code" .
NO >> GO TO 2.
2. CHECK ACCELERATOR PEDAL POSITION SENSOR
Check accelerator pedal position sensor. Refer to EC-272, "
DTC P2138 APP SENSOR" (QR engine) or EC-
652, "DTC P2138 APP SENSOR" (VQ engine).
OK or NG
OK >> GO TO 3.
NG >> Repair or replace accelerator pedal position sensor.

Adjustment of A/T PositionBCS0014X
Move selector lever from “P” position to “1” position. You should be
able to feel the detents in each position. If the detents cannot be felt
or if the pointer indicating the position is improperly aligned, the con-
trol cable needs adjustment.
1. Place selector lever in “P” position.
2. Loosen control cable lock nut and place manual shaft in “P”
position.
CAUTION:
Turn wheels more than 1/4 rotations and apply the park
lock.
3. After pushing the control cable with the specified force, move
your hands off the control cable.
4. Connect control cable on manual shaft.
CAUTION:
No application of a force to the manual lever.
5. Tighten control cable lock nut.
6. Move selector lever from “P” to “1” position again. Make sure that selector lever moves smoothly.
7. Apply grease to contacting areas of selector lever and control cable. Install any part removed.
Checking of A/T PositionBCS0014Y
1. Place selector lever in “P” position, and turn ignition switch ON. (Do not start engine.)
2. Make sure selector lever can be shifted to other than “P” position when brake pedal is depressed. Also
make sure selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move selector lever and check for excessive effort, sticking, noise or rattle.
4. Confirm selector lever stops at each position with the feel of engagement when it is moved through all the
positions. Check whether or not the actual position selector lever is in matches the position shown by the
shift position indicator and transaxle body.
5. The method of operating selector lever to individual positions
correctly should be as shown in the figure.
6. Confirm back-up lamps illuminate only when lever is placed in
“R” position. Confirm back-up lamps do not illuminate when
selector lever is in “P” or “N” position with selector lever pushed
against “R” position.
7. Confirm engine can only be started with selector lever in “P” and
“N” positions.
8. Make sure transaxle is locked completely in “P” position.Specified force: 9.8 N (1.0 kg, 2.2 lb)

A/T SHIFT LOCK SYSTEM

A/T SHIFT LOCK SYSTEMPFP:34950
DescriptionBCS0014Z

The electrical key interlock mechanism also operates as a shift lock:
With the ignition switch turned to ON, selector lever cannot be shifted from “P” to any other position unless
brake pedal is depressed.
With the key removed, selector lever cannot be shifted from “P” to any other position.
The key cannot be removed unless selector lever is placed in “P”.

The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the rotator and slider located inside key cylinder, respectively.

NOTE:
This emergency lever insures that when battery is off ignition key cannot be removed.Inthe situation like this,
by operating this lever, ignition key can be removed.
