Diagnostic Procedure without CONSULT-IIACS008CZ
OBD-II SELF-DIAGNOSTIC PROCEDURE (WITH GST)
Refer to EC-144, "Generic Scan Tool (GST) Function" (for VQ35DE) or EC-835, "Generic Scan Tool (GST)
Function" (for VK45DE).
OBD-II SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)
Refer to EC-69, "Malfunction Indicator Lamp (MIL)" (for VQ35DE) or EC-760, "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 “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 3
.
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.
>> GO TO 3.
3. JUDGEMENT PROCEDURE STEP 2
1. Move the selector lever to the manual shift gate side. (Manual mode switch “ON”.)
2. Release brake pedal. (Stop lamp switch signal “OFF”.)
3. Move the selector lever to “D” position. (Manual mode switch “OFF”.)
4. Depress brake pedal. (Stop lamp switch signal “ON”.)
5. Release brake pedal. (Stop lamp switch signal “OFF”.)
6. Depress accelerator pedal fully and release it.
>> GO TO 4.

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 LINE
Revision: 2005 July 2005 FX
DTC U1000 CAN COMMUNICATION LINEPFP:23710
DescriptionACS002MB
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 LogicACS002MC

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 CauseACS002MD

Harness or connectors
(CAN communication line is open or shorted.)
DTC Confirmation ProcedureACS002ME
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode for “A/T” with CONSULT-II.
3. Start engine and wait for at least 6 seconds.
4. If DTC is detected, go to AT- 1 0 8 , "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-II”.
