OBD-II SELF-DIAGNOSTIC PROCEDURE (WITH GST)
Refer to EC-72, "Generic Scan Tool (GST) Function".
OBD-II SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)
Refer to EC-55, "Malfunction Indicator Lamp (MIL)".
TCM SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)
Description
When the ignition switch is switched “ON”, the A/T CHECK indicator lamp lights up for 2 seconds. As a method
for locating the suspect circuit, w hen the self-diagnostics start signal is input, the memory for the malfunction
location is output and the A/T CHECK indicator lamp flashes to display the corresponding DTC.
Diagnostic Procedure
1.CHECK A/T CHECK INDICATOR LAMP
1. Start the engine with selector lever in “P” pos ition. Warm engine to normal operating temperature.
2. Turn ignition switch ON and OFF at least twice, then leave it in the OFF position.
3. Wait 10 seconds.
4. 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 >> GO TO TM-119, "A/T Check Indicator Lamp Does Not Come On"
.
2.JUDGEMENT PROCEDURE STEP 1
1. Turn ignition switch OFF.
2. Keep pressing shift lock release button.
3. Move selector lever from “P” to “D” position.
4. Release accelerator pedal. (Set the closed throttle position signal “ON”.)
5. Depress brake pedal. (Stop lamp switch signal “ON”.)
6. Turn ignition switch ON. (Do not start engine.)
7. Wait 3 seconds.
8. Move the selector lever from “D” to “3” position.
9. Release brake pedal. (Stop lamp switch signal “OFF”.)
10. Move the selector lever from “3” to “2” position.
11. Depress brake pedal. (Stop lamp switch signal “ON”.)

12. Depress accelerator pedal fully and release it.>> GO TO 3.
3.CHECK SELF-DIAGNOSIS CODE
Check A/T CHECK indicator lamp.
Refer to "Judgement Self-diagnosis Code".
If the system does not go into self-diagnostics. Refer to TM-44, "Diagnosis Procedure"
, TM-94, "Diagnosis
Procedure", TM-95, "Diagnosis Procedure".
>> DIAGNOSIS END
Judgement Self-diagnosis Code
If there is a malfunction, the lamp lights up fo r the time corresponding to the suspect circuit.
Erase Self-diagnosis
 In order to make it easier to find the cause of hard-to-duplicate malfunctions, malfunction information is
stored into the control unit as necessary during use by the user. This memory is not erased no matter how
many times the ignition switch is turned ON and OFF.
 However, this information is erased by turning igni tion switch OFF after executing self-diagnostics or by
erasing the memory using the CONSULT-III.
