Trouble Diagnosis with CONSULT
INFOID:0000000012430606
1. Connect CONSULT.
2. DTC is displayed on SELF-DIAG RESULTS.
NOTE:
If a malfunction is not detected on “SELF-DIAG RESULTS [CURRENT]”, but a malfunction is detected during
SRS Operation Check, the following cases may exist:
• “SELF-DIAG [PAST]” memory might not be erased. Refer to SRC-14, "
On Board Diagnosis Function".
• SRS system malfunctions intermittently. Refer to SRC-41, "
InspectionProcedure".
DIAGNOSIS MODE
1. Connect CONSULT.
2. Confirm that zero point reset of OCS is complete.
3. If no DTCs are detected on “SELF-DIAG RESULTS [CURRE NT]”, repair of SRS is completed. Go to step
4.
If any DTCs are detected on “SELF-DIAG RESULT S [CURRENT]”, the malfunction has not been repaired
completely or another malfunction is being detected. Perform SRS Operation Check again. Refer to SRC-
14, "On Board Diagnosis Function".
4. Touch “ERASE”. NOTE:
Touching “ERASE” will clear the SRS memory of the malfunction (“SELF-DIAG [PAST]”). If “SELF-
DIAG [PAST]” is not erased, User Mode may sh ow the previous system malfunction even if the
malfunction has been repaired completely.
5. Check that no malfunction is det ected in “SELF-DIAG [PAST]”.
6. Exit Diagnosis Mode and disconnect the CONSULT.
7. Perform SRS Operation Check. Refer to SRC-14, "
On Board Diagnosis Function".
SRS HISTORY CHECK
1. Check repair history of the SRS. If no repairs have been made, perform SRC-14, "On Board Diagnosis
Function". If repairs have been made, GO TO step 2.
2. Erase ”SELF-DIAG [PAST]” after repair. Refer to SRC-14, "
On Board Diagnosis Function".
CONSULT Function (AIR BAG)INFOID:0000000012430607
CONSULT can display each diagnostic item using the diagnostic test modes shown following.
Diagnostic Test ModeDiagnostic Item Description
Self Diagnostic Result SEL F-DIAG RESULT [CURRENT]A current Self-diagnosis result (also indicated by the number of
warning lamp flashes in the Diagnosis mode) is displayed on the
CONSULT screen in real time. This refers to a malfunctioning part
requiring repairs.
Data Monitor DATA MONITOR Displays air bag diagnosis sensor unit input/output data in real time.
ECU Identification ECU DISCRIMINATED NO. Air bag diagnosis sensor unit ECU discriminated number (identifica-
tion number) or part number is displayed. Air bag diagnosis sensor
unit has individual ECU discriminated number (identification num-
ber) or part number based on model and equipment.
Trouble Diagnostic Record TR OUBLE DIAG RECORD [PAST] With TROUBLE DIAG RECORD, diagnosis results previously
erased by a reset operation can be displayed on the CONSULT
screen.

How to read flash codes
1. Put the vehicle in Diagnosis Mode. Refer to SRC-14, "On Board Diagnosis Function".
2. All codes are proceded by a seven second "holding" flash.
3. Identify how many primary flashes are display ed as well as the length of each primary flash.
4. Refer to the tables and examples below to determine which SRS subsystem the code belongs to.
5. Count the short secondary flashes that follow the primary flashes.
6. Match the correct flashing pattern to the malfunctioning component and perform the Diagnosis Procedure.
Refer to the illustrations below fo r an example of each flashing pattern.

INFOID:0000000012430612
Always perform zero point reset using CONSULT when removing and installing the passenger seat or servic-
ing the occupant classification system. If zero point reset is not performed the OCS may not operate normally,
which may increase the risk of serious injury in a collision.

WORK PROCEDURE WHEN REPLACING CONTROL UNIT
1.PERFORM ZERO POINT RESET
Perform zero point reset. Refer to SRC-39, "
ZERO POINT RESET : Special Repair Requirement".
Is zero point reset performed normally?
YES >> INSPECTION END
NO >> Check condition as per the following, and perform zero point reset again. • Passenger seat is occupied by an object.
• Excessive vibration is applied while performing zero point reset.
• Occupant detection system is malfunctioning.NOTE:
If “Incomplete” is displayed on “zero point reset cu rrent status”, zero point reset is not completed
normally. Check the condition as per the following and perform zero point reset again.
• Passenger seat is occupied by an object.
• Excessive vibration is applied while performing zero point reset.
• Occupant detection system is malfunctioning.
ZERO POINT RESET
ZERO POINT RESET : DescriptionINFOID:0000000012430614
Zero point reset is an initializing procedure for occupant detection sensor that must be performed when replac-
ing or removing and installing passenger seat.
If zero point reset is not performed, the initializati on is incomplete and Occupant Detection System does not
operate normally.
NOTE:
• When zero point reset is performed once after removal and installation of passenger seat, CONSULT dis- plays “complete”.
• When reinstalling passenger seat after removal, the initial value for occupant detection sensor changes, and
Occupant Detection System does not operate normally.
• Always perform zero point reset after performing the work as per the following.
- Reinstallation of passenger seat
- Installation of passenger seat that is zero point reset complete
- Installation of passenger seat that is zero point reset in complete
ZERO POINT RESET : Special Repair RequirementINFOID:0000000012430615
1.PERFORM ZERO POINT RESET
1. Perform zero point reset. NOTE:
When performing zero point reset, be careful of the items described as per the following.
• Perform zero point reset after installing passenger seat to the vehicle
• Do not put any objects on passenger seat
• Do not apply excessive vibration to the vehicle
• Do not touch the vehicle
• Do not tilt the vehicle

TION”.
2. Check that “Complete” or “Incomplete” is displayed on “Zero point reset status”.
CAUTION:
• “Complete” is displayed on “zero point reset current status” if the seat is reinstalled by seat removal
and installation, or “zero point reset” is already performed.

U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000012430674
CAN (Controller Area Network) is a serial communication system for real time application. It is an on-vehicle
multiplex communication system with high data communication speed and excellent error detection ability.
Many electronic control units are equipped into vehicl es, and each control unit shares information and links
with other control units during operation. With CAN co mmunication, control units are connected with two com-
munication lines (CAN-H line, CAN-L line) allowing a hi gh rate of information transmission with less wiring.
Each control unit transmits and receives data but selectively reads required data only. Refer to LAN-30, "

COMMUNICATION SYSTEM : CAN Communication Signal Chart".

FUNCTION
CONSULT can display each diagnostic item usi ng the diagnostic test modes shown following:
*: The following diagnosis information is cleared by erasing:
•DTC
• Freeze frame data (FFD)
ECU IDENTIFICATION
Displays the part number stored in the control unit.
SELF DIAGNOSTIC RESULT MODE
Refer to STC-10, "DTC Index".
When “CRNT” is displayed on “Self Diagnostic Result”.
• The system is presently malfunctioning.
When “PAST” is displayed on “Self Diagnostic Result”.• System malfunction in the past is detect ed, but the system is presently normal.
FREEZE FRAME DATA (FFD)
The following vehicle status is recorded when DTC is detected and is displayed on CONSULT:
DATA MONITOR MODE
*1: Almost in accordance with the value of “MOTOR S IG”. It is not a malfunction though these values are not
accorded when steering quickly.
Diagnostic test mode Function
ECU Identification The part number stored in the control unit can be read.
Self Diagnostic Result Self-diagnostic results and freeze frame data can be read and erased quickly.
*

Item name Display item
IGN COUNTER
(0-39) The number of times that ignition switch is tu
rned ON after the DTC is detected is displayed.
• When “0” is displayed: It indicates that the system is presently malfunctioning.
• When except “0” is displayed: It indicates that system malfunction in the past is detected, but the system is pres-
ently normal.
NOTE:
Each time when ignition switch is turned OFF to ON, numerical number increases in 1 →2→3...38 →39.
When the operation number of times exceeds 39, the number does not increase and “39” is displayed until self-
diagnosis is erased.
