TROUBLE DIAGNOSIS
HOW TO CHANGE BETWEEN SELF-DIAGNOSIS MODE AND USER MODE WITH CONSULT-III
From User Mode to Diagnosis Mode
After selecting “AIR BAG” on the “SELECT SYSTEM” screen, User mode automatically changes to Diagnosis
mode.
From Diagnosis Mode to User Mode
To return to User mode from Diagnosis mode, touch “BACK” key of CONSULT-III until “SELECT SYSTEM”
appears, Diagnosis mode automatically changes to User mode.
HOW TO ERASE SELF-DIAGNOSIS RESULTS
NOTE:
If the memory in “SELF-DIAG [PAST]” is not erased, User mode will continue to show the system mal-
function by the operation of th e warning lamp even if the malfun ction is repaired completely.
• “SELF-DIAG [CURRENT]” A current self-diagnosis result is displayed on the CO NSULT-III screen in real time. After the malfunction is
repaired completely, no malfunction is detected on “SELF-DIAG [CURRENT]”.
• “SELF-DIAG [PAST]” Return to the “SELF-DIAG [CURRENT]” CONSULT-III screen by touching “BACK” key of CONSULT-III and
select “SELF-DIAG [CURRENT]” in SELECT DIAG MODE. Touch “ERASE” in “SELF-DIAG [CURRENT]”
mode.
• “TROUBLE DIAG RECORD”
The memory of “TROUBLE DI AG RECORD” cannot be erased.
Self-Diagnosis Function (Without CONSULT-III)INFOID:0000000006211121
The reading of these results is accomplished using one of two modes — “User mode” and “Diagnosis mode”.
HOW TO CHANGE BETWEEN USER MODE AND SELF-DIAGNOSIS MODE WITHOUT CONSULT-
AIR BAG diagnostic mode Description
SELF-DIAG [CURRENT] A current Self-diagnosis result is displayed on the CO
NSULT-III screen in real time. This refers to a mal-
functioning part requiring replacement.
SELF-DIAG [PAST] Diagnosis results previously stored in the memory are displayed on the CONSULT-III screen. The
stored results will remain until the memory is erased.
TROUBLE DIAG RECORD With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be dis-
played on the CONSULT-III screen.
ECU DISCRIMINATED NO. Air bag diagnosis sensor unit ECU discriminated number (identification number) is displayed. Air bag
diagnosis sensor unit has individual ECU discriminated number (identification number) based on model
and equipment.
PASSENGER AIR BAG The STATUS (readiness) of the front passenger air bag module is displayed. The STATUS displayed
(ON/OFF) depends on the signals supplied to the occupant classification system control module and
air bag diagnosis sensor unit. Refer to
SRS-6, "
Occupant Classification System (OCS)" for more in-
formation.

REMOVAL
WARNING:
When servicing the SRS, do not work from directly in front of air bag module.
CAUTION:
• Before servicing the SRS, turn ignition switch OFF, disconnect both battery terminals and wait at
least three minutes.
• Do not tap or bump the steering wheel.
• Do not disassemble the spiral cable.
• Do not allow oil, grease or water to co me in contact with the spiral cable.
• Replace the spiral cable if it has b een dropped or sustained an impact.
• With the steering linkage disconn ected, the spiral cable may snap by turning the steering wheel
beyond the limited number of turns. The spiral cable can be turned counterclockwise about 2.5 turns
from the neutral position.
1. Set the front wheels to the straight-ahead/neutral position.
2. Disconnect the negative and positive battery term inals, then wait at least three minutes.
3. Remove the steering wheel. Refer to PS-7, "
Removal and Installation".
4. Remove the column cover upper and lower.
5. Disconnect wiper and washer switch connector (1). Then while pressing tabs (2), pull wiper and washer switch away from spiral
cable to remove.

6. Disconnect lighting and turn signal switch connector (1). Thenwhile pressing tabs (2), pull lighting and turn signal switch
toward driver door to remove.
7. Remove the screws, then release the tab at the top and pull the spiral cable away from the steering column assembly.
8. Disconnect spiral cable connectors.
INSTALLATION
Installation is in the reverse order of removal.
• Align spiral cable correctly when installing steering wheel. Make sure spiral cable alignment and centering marks (B) are matched
and in the neutral position. The neutra l position is detected by turn-
ing left 2.5 revolutions from the right end position, ending with the
locating pin (A) at the top. Place steering wheel in straight ahead
position, then install it with the locating pin hole (C) directly over
spiral cable locating pin.
• After the work is completed, perform self-diagnosis to make sure
no malfunction is detected. Refer to SRS-19, "
SRS Operation
Check".
