Diagnostic Procedure without CONSULT-IINCS001KI
OBD-II SELF-DIAGNOSTIC PROCEDURE (WITH GST)
Refer to EC-146, "Generic Scan Tool (GST) Function" (for VQ35DE engine), EC-859, "Generic Scan Tool
(GST) Function" (for VK45DE engine).
OBD-II SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)
Refer to EC-69, "Malfunction Indicator Lamp (MIL)" (for VQ35DE engine), EC-780, "Malfunction Indicator
Lamp (MIL)" (for VK45DE engine).
TCM SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)
Description
As a method for locating the suspect 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.
Operation 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 ON. (Do not start engine.)
Does A/T CHECK indicator lamp come on for about 2 seconds?
YES >> GO TO 2.
NO >> GO TO AT-190, "
A/T CHECK Indicator Lamp Does Not Come On" .
2. JUDGEMENT PROCEDURE
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.
7. Wait 3 seconds.
8. Move the selector lever to the manual shift gate side. (Manual mode signal ON.)
9. Release brake pedal. (Stop lamp switch signal OFF.)
10. Move the selector lever to “D” position. (Manual mode signal 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-104, "
Judgement Self-diagnosis Code" .
If the system does not go into self-diagnostics. Refer to AT- 11 3 , "
DTC P0705 PARK/NEUTRAL POSITION
SWITCH" , AT- 1 8 4 , "CLOSED THROTTLE POSITION AND WIDE OPEN THROTTLE POSITION CIRCUIT" ,
