DIAGNOSIS SYSTEM (AIRBAG)

Description

INFOID:0000000008843270

CAUTION:

• Never use electrical test equipment on any circuit related to the SRS unless instructed in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

• Never repair, splice or modify the SRS wiring harness. If the harness is damaged, replace it with a

new one.

• Keep ground portion clean.

DIAGNOSIS FUNCTION

• The SRS self-diagnostic results can be read with air bag warning lamp and/or CONSULT.
• The user mode is exclusively prepared for the customer (driver). This mode warns the driver of a system

malfunction through the operation of the air bag warning lamp.

• The diagnosis mode allows the technician to locate and inspect the malfunctioning part.
• The mode applications for the air bag warning lamp and CONSULT are as per the following items.

On Board Diagnosis Function

INFOID:0000000008843271

ON-BOARD DIAGNOSIS

There are two self diagnosis functions with air bag warning lamp as per the following items.
• USER MODE
• DIAGNOSIS MODE

METHOD OF STARTING

• Diagnosis mode changes from user mode to diagnosis mode when changing operation is performed.
• In user mode, when SRS air bag warning lamp is not blinking, changing to diagnosis mode by ignition switch

operation is not possible.

• In diagnosis mode, when repair is complete and system is normal, the mode changes to user mode when

ignition switch is turned from OFF to ON.

Procedure to Change Diagnosis Mode

1.

Turn ignition switch from OFF to ON.

2.

SRS air bag lamp turns ON for 7 second and turns OFF, then turn ignition switch OFF within 2 second
after the lamp turns OFF.

3.

After turning ignition switch OFF, wait for 3 seconds or more.

4.

Repeat operation 1 to 3 for 2 times so that operation 1 to 3 is repeated for 3 times in total.

5.

Turn ignition switch from OFF to ON. Diagnosis mode changes.

USER MODE

In USER MODE, air bag warning lamp on combination meter blinks when a malfunction is detected and warns
the customer (driver).

How to Read Air Bag Warning Lamp

1.

Turn the ignition switch from OFF to ON, and check that the air bag warning lamp blinks.

2.

Compare the air bag warning lamp blinking pattern with the examples.

DIAGNOSIS SYSTEM (AIRBAG)

Occurrence of Intermittent Malfunction

Air bag warning lamp blinks in user mode when an intermittent malfunction occurs. Air bag warning lamp turns
OFF when system returns to normal status.

Battery Low Voltage Detection

Air bag diagnosis sensor unit warns the driver by turning air bag warning lamp ON when air bag diagnosis
sensor unit detects battery low voltage. Air bag warning lamp turns ON when a voltage value at which air bag
diagnosis sensor unit cannot operate normally (9 V or less) is detected for 10 seconds or more. After starting
to turn ON, air bag warning lamp turns OFF when air bag diagnosis sensor unit detects the normal value of
battery voltage for 10 seconds or more.

The mode cannot be switched to diagnosis mode by ignition switch while air bag warning lamp turns ON due
to this cause. 

Battery High Voltage Detection

Air bag diagnosis sensor unit warns the driver by turning air bag warning lamp ON when air bag diagnosis
sensor unit detects battery high voltage. Air bag warning lamp turns ON when a voltage value at which air bag
diagnosis sensor unit cannot operate normally (16 V or more) is detected for 3 seconds or more. After starting
to turn ON, air bag warning lamp turns OFF when air bag diagnosis sensor unit detects the normal value of
battery voltage for 3 seconds or more. 
The mode cannot be switched to diagnosis mode by ignition switch while air bag warning lamp turns ON due
to this cause.

DIAGNOSIS MODE

The diagnosis mode can only be switched when a malfunction is detected in the user mode. Malfunctioning
system is indicated according to blinking pattern of air bag warning lamp.

How to Read Air Bag Warning Lamp

1.

Follow the procedures of “PROCEDURE TO CHANGE DIAGNOSIS MODE”, and switch to the diagnosis
mode.

2.

Turn ignition switch ON. Check the blinking pattern of air bag warning lamp.
There are 4 blinking patterns for the air bag warning lamp as per the following items. 
• Front air bag system: Two 1.5 seconds blinks followed by a 0.5 seconds blink repeated.
• Side air bag system: Three 1.5 seconds blinks followed by a 0.5 seconds blink repeated.
• Air bag control unit system: 3 seconds blink followed by a 0.5 seconds blink repeated.
• Sensor system: Two 3 seconds blinks followed by a 0.5 seconds blink repeated.

U1000 CAN COMM CIRCUIT

Description

INFOID:0000000008843362

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.
