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" .

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.
