Diagnostic Procedure Without CONSULT-IIACS007AJ
OBD-II SELF-DIAGNOSTIC PROCEDURE (WITH GST)
Refer to EC-122, "Generic Scan Tool (GST) Function" (for VG35DE) or EC-772, "Generic Scan Tool (GST)
Function" (for VK45DE).
OBD-II SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)
Refer to EC-68, "Malfunction Indicator Lamp (MIL)" (for VG35DE) or EC-717, "Malfunction Indicator Lamp
(MIL)" (for VK45DE).
TCM SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)
Description
In the unlikely event of a malfunction in the electrical system, when the ignition switch is switched “ON”, the A/
T CHECK indicator lamp lights up for 2 seconds, then flashes for 8 seconds. If there is no malfunction, when
the ignition switch is turned “ON”, the indicator lamp lights up for 2 seconds. As a method for locating the sus-
pect circuit, when 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” position. 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 to “ON” position. (Do not start engine.)
Does A/T CHECK indicator lamp come on for about 2 seconds?
YES >> GO TO 2.
NO >> GO TO AT- 1 9 1 , "
A/T CHECK Indicator Lamp Does Not Come On" .
2. JUDGEMENT PROCEDURE STEP 1
1. Turn ignition switch “OFF”.
2. Push 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 to the Manual shift gate side. (Manual mode switch “ON”.)
9. Release brake pedal. (Stop lamp switch signal “OFF”.)
10. Move the selector lever to “D” position. (Manual mode switch “OFF”.)
11. Depress brake pedal. (Stop lamp switch signal “ON”.)
12. Release brake pedal. (Stop lamp switch signal “OFF”.)
13. Depress accelerator pedal fully and release it.
>> GO TO 3.
3. CHECK SELF-DIAGNOSIS CODE
Check A/T CHECK indicator lamp.
Refer to AT- 1 0 4 , "
Judgement Self-diagnosis Code" .
If the system does not go into self-diagnostics. Refer to AT- 11 2 , "

DescriptionACS007BI

The torque converter clutch solenoid valve is activated, with the gear in D4 , D5 by the TCM in response
to signals sent from the vehicle speed sensor and accelerator pedal position sensor (throttle position sen-
sor). Torque converter clutch piston operation will then be controlled.

Lock-up operation, however, is prohibited when A/T fluid temperature is too low.

When the accelerator pedal is depressed (less than 1/8) in lock-up condition, the engine speed should not
change abruptly. If there is a big jump in engine speed, there is no lock-up.
