TROUBLE DIAGNOSIS
a. Touch “SELF-DIAG [CURRENT]”.
Diagnostic code is displayed on “SELF-DIAG [CURRENT]”.
i. If the malfunction is displayed in the “SRS Operation Check” (Air bag warning lamp blinking) but no mal-
function is displayed in the “SELF-DIAG [CURRENT]”, the following possibilities shall be checked. Refer
to SRS-21, "
DIAGNOSTIC PROCEDURE 3" .
Low battery voltage (Less than 9 V)
After the malfunction part is repaired, the diagnosis results in “SELF-DIAG [PAST]” has not been
erased.
An intermittent malfunction has been stored in the past.
NOTE:
Intermittent malfunction is a malfunction that has occurred once in the past, but soon recovered.
b. Touch “SELF-DIAG [PAST]”.
The diagnostic code is displayed until erasing the memory in
the “SELF-DIAG [CURRENT]”.
c. Touch “TROUBLE DIAG RECORD”.
The diagnosis results (malfunction parts stored in the diagno-
sis sensor unit) stored in the self-diagnosis results are dis-
played.
The memory of “TROUBLE DIAG RECORD” cannot be
erased.
7. Each diagnostic code is displayed. Refer to SRS-22, "
Diagnostic
Code Chart" .
8. Touch “PRINT”, if required.
9. Based on each diagnosis result, repair or replace the malfunc-
tion parts.
CAUTION:
Be sure to start the work after the following steps. Turn the
ignition switch OFF, and disconnect both battery cables.

DIAG [CURRENT]” screen, and check the display.
13. Turn ignition switch OFF, then turn off and disconnect CONSULT-II.
14. Turn ignition switch ON, and check the system with the SRS air bag warning lamp (User mode).
15. Check that no malfunction is detected. Now the diagnosis is complete.
DIAGNOSTIC PROCEDURE 3
Inspecting SRS Malfunctioning Record
If any malfunction is detected in “SRS Operation Check”, but no malfunction is detected in “SELF-DIAG [CUR-
RENT]” on CONSULT-II, carry out the following steps.
1. CHECK BATTERY VOLTAGE
Disconnect both battery cables and check that the battery voltage is 9 V or more.
OK or NG
OK >> GO TO 2.
NG >> Charge the battery.
2. CONSIDER POSSIBILITY OF NOT ERASING SELF-DIAGNOSTIC RESULT AFTER REPAIRING.
Is it the first time for maintenance of SRS?
YES or NO
YES >> GO TO 3.
NO >> Erase the self-diagnostic results, and Check the “SRS Operation Check”. Refer to SRS-17, "
SRS
Operation Check" .
3. CHECK “SELF-DIAG [PAST]” BY CONSULT-II
Store the memory in “SELF-DIAG [PAST]”.
YES or NO
YES >> Repair the part of “SELF-DIAG[PAST]”.
NO >> Check the “TROUBLE DIAG RECORD”, and then repair it. Refer to SRS-22, "
Diagnostic Code
Chart" .
