Diagnosis Procedure without CONSULT-III

INFOID:0000000001282759

OBD-II SELF-DIAGNOSTIC PROCEDURE (WITH GST)

Refer to

EC-83, "Generic Scan Tool (GST) Function"

(VQ40DE) or

EC-551, "Generic Scan Tool (GST) Func-

tion"

(VK56DE).

OBD-II SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)

Refer to

TM-34, "Malfunction Indicator Lamp (MIL)"

TCM SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)

Description

When the ignition switch is switched “ON”, the O/D OFF indicator lamp lights up for 2 seconds. 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 O/D OFF indicator lamp flashes to display the corresponding DTC.

Diagnostic Procedure

CHECK O/D OFF INDICATOR LAMP

Start the engine with selector lever in “P” position. Warm engine to normal operating temperature.

Turn ignition switch ON and OFF at least twice, then leave it in the OFF position.

DIAGNOSIS SYSTEM (TCM)

TM-43

< FUNCTION DIAGNOSIS >

Wait 10 seconds.

Turn ignition switch ON. (Do not start engine.)

Does O/D OFF indicator lamp come on for about 2 seconds?

YES

>> GO TO 2.

>> GO TO

TM-126, "O/D OFF Indicator Lamp Does Not Come On (Without Manual Mode)"

CHECK VEHICLE EQUIPMENT

Is vehicle equipped with manual mode?

YES or NO?

YES

>> GO TO 3.

>> GO TO 4.

JUDGEMENT PROCEDURE STEP 1 (WITH MANUAL MODE)

Turn ignition switch OFF.

Keep pressing shift lock release button.

Move selector lever from “P” to “D” position.

Release accelerator pedal. (Set the closed throttle position signal “ON”.)

Depress brake pedal. (Stop lamp switch signal “ON”.)

Turn ignition switch ON (Do not start engine.)

Wait 3 seconds.

Move the selector lever to the manual shift gate side. (Manual mode signal "ON".)

Release brake pedal. (Stop lamp switch signal “OFF”.)

10. Move the selector lever to "D" position. (Manual mode signal ON.)
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 5.

JUDGEMENT PROCEDURE STEP 1 (WITHOUT MANUAL MODE)

Turn ignition switch OFF.

Keep pressing shift lock release button.

Move selector lever from “P” to “D” position.

Release accelerator pedal. (Set the closed throttle position signal “ON”.)

Depress brake pedal. (Stop lamp switch signal “ON”.)

Turn ignition switch ON. (Do not start egine.)

Wait 3 seconds.

Move the selector lever from “D” to “3” position.

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 5.

CHECK SELF-DIAGNOSIS CODE

Check O/D OFF indicator lamp.
Refer to "Judgement Self-diagnosis Code".
If the system does not go into self-diagnostics. Refer to

< FUNCTION DIAGNOSIS >

DIAGNOSIS SYSTEM (TCM)

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 executing self-diagnostics or by

erasing the memory using the CONSULT-III.

DTC U1000 CAN COMMUNICATION LINE

< COMPONENT DIAGNOSIS >

COMPONENT DIAGNOSIS

DTC U1000 CAN COMMUNICATION LINE

Description

INFOID:0000000001282760

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 Logic

INFOID:0000000001282761

• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “U1000 CAN COMM CIRCUIT” with CONSULT-III or 17th judgement flicker without

CONSULT-III is detected when TCM cannot communicate to other control units.

Possible Cause

INFOID:0000000001282762

Harness or connectors
(CAN communication line is open or shorted.)

DTC Confirmation Procedure

INFOID:0000000001282763

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-III

Turn ignition switch “ON”. (Do not start engine.)

Select “DATA MONITOR” mode for “ENGINE” with CONSULT-III.

Start engine and wait for at least 6 seconds.

If DTC is detected, go to

TM-45, "Diagnosis Procedure"

WITH GST

Follow the procedure “WITH CONSULT-III”.
