< SYSTEM DESCRIPTION >

DIAGNOSIS SYSTEM (AIR BAG)

When driver air bag module (Item display 1) and satellite sensor RH (Item display2) are malfunctioning.

CONSULT-III Function

INFOID:0000000006439853

APPLICATION ITEM

CONSULT-III performs the following functions.

HOW TO ERASE SELF DIAGNOSTIC RESULTS

• “Self Diagnostic Result”

A current self-diagnostic result is displayed on CONSULT-III screen in real time.
After the malfunction is repaired completely, no malfunction is detected on “Self Diagnostic Result”.

• “SELF-DIAG [PAST]”

Return to “Self Diagnostic Result” CONSULT-III screen by touching the “BACK” key of CONSULT-III and
select “Self Diagnostic Result” in SELECT DIAG MODE. Touch “Erase” in “Self Diagnostic Result” mode.
NOTE:
If the memory of the malfunction in “SELF-DIAG [PAST]” is not erased, the user mode shows the system
malfunction by the illumination of the warning lamp even if the malfunction is repaired completely.

• “TROUBLE DIAG RECORD”

The memory of “TROUBLE DIAG RECORD” cannot be erased.

• “SELF-DIAG RESULT [CAN]”

Self-diagnosis result other than “SELF-DIAG RESULT [CAN]” is erased when touching “Erase”.

SPECIAL FUNCTION

CAUSE OF WARNING

This item indicates IGN low or high voltage condition.
The air bag warning lamp blink in user mode when the battery voltage is lowered to the voltage value (less
than 9 V or higher to the voltage more than 16V) at which the SRS cannot be operated normally. The air bag
warning lamp turns OFF after the battery voltage returns to normal status after blinking.

Diagnosis mode

Description

ECU Identification

Air bag diagnosis sensor unit ECU discriminated number (identification num-
ber) is displayed. Air bag diagnosis sensor unit has individual ECU discriminat-
ed number (identification number) based on model and equipment.

Self Diagnostic Result

The current self diagnosis results (also indicated with the number of air bag
warning lamp blinks in the diagnosis mode) are displayed on CONSULT-III
screen in real time. This refers to a malfunctioning part requiring repairs.
Refer to

SRC-18, "DTC Index"

Function Test

CAR COMPUTER DIAG.

Test result is indicated using “OK” or “NG” so that the customer recognizes eas-
ily.

Special function

SELF-DIAG [PAST]

Diagnosis results previously stored in the memory are displayed on CONSULT-
III screen. The stored results are not erased until memory erasing is executed.

TROUBLE DIAG RECORD

With TROUBLE DIAG RECORD, diagnosis results previously erased by a re-
set operation can be displayed on CONSULT-III screen.

SELF-DIAG RESULT [CAN]

Self-diagnosis result other than “SELF-DIAG RESULT [CAN]” is erased when
touching “Erase”.

CAUSE OF WARNING

It displays the cause of warning lamp illumination that is not recorded in mem-
ory.

DIAGNOSIS SYSTEM (AIR BAG)

SRC-17

< SYSTEM DESCRIPTION >

SRC

In such a case, the DTC memory is not performed and changing to the self-diagnostic mode by IGN operation
cannot be performed while the air bag warning lamp illuminates. “NO DTC” is displayed even if the malfunc-
tioning parts are checked by CONSULT-III.
This function records the following items.

DTC/CIRCUIT DIAGNOSIS

U1000 CAN COMM CIRCUIT

Description

INFOID:0000000006439857

CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control unit, and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected
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.
