DISPLAY OF SELF-DIAGNOSTIC RESULTS
The results of self-diagnosis are shown by flash patterns of HlCAS BR
warning lamp.
Display when past data shows that fail-safe function
has been activated previously
Only an abnormal item is indicated by the pattern shown in the ~8 left figure. The pattern is repeated.
Display when past data shows that fail-safe function
has not been activated previously EL
If all items are normal, HlCAS warning lamp flashes at a fre-
quency of
4 Hz. sD
If system is in fail-safe mode, only an abnormal item is indi-
cated by the pattern shown in the left figure. The pattern
is
repeated.

a The screens for "SELF-DIAG [CURRENTJ", "SELF-DIAG [PAST]" and "TROUBLE DlAG RECORD" share the same message. Follow the repair procedures in numerical order. Check whether a malfunction is eliminated each time a repair item is
finished, and when the malfunction is eliminated, further repair work is not required.
After repairing the system, touch "ERASE" to clear the memory and check with CONSULT again.
If both seat belt pre-tensioner systems on the driver seat and passenger seat have failed at the same time, only one of
the two failures is displayed first. The other failure is displayed after the first failure is repaired. For seat belt pre-tensioner
systems,
only
"SELF-DIAG [CURRENTJ" is displayed; "SELF-DIAG

and "TROUBLE DlAG RECORD" are not dis-
played.

TROUBLE DIAGNOSIS RECORD
If a malfunction has occurred but is not recorded on seif-diagnosis,
it may be caused by some past malfunction. In such a case, past
malfunctions can be found
by selecting "TROUBLE DlAG
RECORD" in Diagnosis mode.
The "TROUBLE DlAG RECORD" can be selected for SRS air
bag system only.

The diagnosis modes are User mode and Diagnosis mode.
Switching between the two modes is accomplished by using
ignition switch
and driver door switch.
When lamp is not flashing (indicating no malfunction) in User mode, operating the door switch cannot change
the mode to Diagnosis mode.
When no malfunction is detected in Diagnosis mode, turning the ignition switch from "OFF" to "ON" changes
the mode to User mode. SRB0395D
