If no self-diagnostic failure is detected on ``SELF-DIAG [CUR-
RENT]'' even though malfunction is detected in SRS Operation
Check (User mode), check the battery voltage. If the battery volt-
age is less than 9V, charge the battery. Then go to DIAGNOSTIC
PROCEDURE 3, page RS-34. If the battery voltage is OK, go to
DIAGNOSTIC PROCEDURE 4, page RS-36, to diagnose the fol-
lowing cases:
+Self-diagnostic failure ``SELF-DIAG [PAST]'' (previously stored
in the memory) might not be erased after repair.
+The SRS system malfunctions intermittently.
8. Touch ``PRINT''.
9. Compare diagnostic codes to ``CONSULT DIAGNOSTIC CODE
CHART'', page RS-33.
10. Touch ``BACK'' key of CONSULT until ``SELECT SYSTEM''
appears in order to return to User mode from Diagnosis mode,
then turn off CONSULT.
11. Turn ignition switch ``OFF'', then disconnect CONSULT and
both battery cables.
12. Repair the system as outlined by the ``Repair order'' in ``CON-
SULT DIAGNOSTIC CODE CHART'', that corresponds to the
problem code. For replacement procedure of component parts,
refer to RS-12.
13. After repairing the system, go to DIAGNOSTIC PROCEDURE
3, page RS-34 for ®nal checking.
CONSULT can only show one seat belt pre-tensioner malfunc-
tion as self-diagnosis result at a time. Check self-diagnosis
result with CONSULT whether other malfunctions are detected
after repairing one seat belt pre-tensioner malfunction.
