Diagnostic Procedure without CONSULT-IINCS001KI
OBD-II SELF-DIAGNOSTIC PROCEDURE (WITH GST)
Refer to EC-135, "Generic Scan Tool (GST) Function" (for VQ35DE engine), EC-838, "Generic Scan Tool
(GST) Function" (for VK45DE engine).
OBD-II SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)
Refer to EC-70, "Malfunction Indicator Lamp (MIL)" (for VQ35DE engine), EC-772, "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- 1 9 0 , "
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- 1 0 4 , "

Judgement Self-diagnosis Code
If there is a malfunction, the lamp lights up for 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 ignition switch OFF after performing self-diagnostics or by
erasing the memory using the CONSULT-II.

DTC U1000 CAN COMMUNICATION LINEPFP:23710
DescriptionNCS001KJ
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent malfunction detection ability.
Many electronic control units are equipped onto a vehicle, and each control unit shares information and links
with other control units during operation (not independent). In CAN communication, control units are con-
nected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission
with less wiring. Each control unit transmits/receives data but selectively reads required data only.
On Board Diagnosis LogicNCS001KK

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “U1000 CAN COMM CIRCUIT” with CONSULT-II or 17th judgement flicker with-
out CONSULT-II is detected when TCM cannot communicate to other control units.
Possible CauseNCS001KL
Harness or connectors
(CAN communication line is open or shorted.)
DTC Confirmation ProcedureNCS001KM
