SRS Operation Check
DIAGNOSTIC PROCEDURE 1
Checking Air Bag Operation by Using ªAIR BAGº
Warning Lamp Ð User Mode
1. After turning ignition switch from ªOFFº to ªONº, ªAIR BAGº
warning lamp operates.
2. Compare ªAIR BAGº warning lamp operation to the chart below.
ªAIR BAGº warning lamp operation Ð User mode Ð SRS condition Reference item
MRS095A
No malfunction is detected.
No further action is neces-
sary.Ð
MRS096A
The system is malfunction-
ing and needs to be repaired
as indicated.Go to DIAGNOSTIC PRO-
CEDURE 2 or 6 (RS-37 or
RS-46).
MRS097A
Air bag or/and seat belt pre-
tensioner is deployed.Go to COLLISION DIAGNO-
SIS (RS-57).

sor unit or harness is mal-
functioning and needs to be
repaired.Go to DIAGNOSTIC PRO-
CEDURE 9 (RS-54).
MRS098A
One of the following has
occurred and needs to be
repaired.
IMeter fuse is blown.
ªAIR BAGº warning lamp
circuit has open or short.
IDiagnosis sensor unit is
malfunctioning.Go to DIAGNOSTIC PRO-
CEDURE 10 (RS-56).
NOTE:
If ªAIR BAGº warning lamp operates differently from the
operations shown above, refer to ªAIR BAGº warning lamp
operation Ð Diagnosis mode Ð,DIAGNOSTIC PROCEDURE 6

If no malfunction is detected on ªSELF-DIAG [CURRENT]º but mal-
function is indicated by the ªAIR BAGº warning lamp, go to DIAG-
NOSTIC PROCEDURE 4, page RS-42, to diagnose the following
situations:
ISelf-diagnostic result ªSELF-DIAG [PAST]º (previously stored
in the memory) might not be erased after repair.
IThe SRS system malfunctions intermittently.
8. Touch ªPRINTº.
9. Compare diagnostic codes to ªCONSULT-II Diagnostic Code
Chartº, page RS-38.
10. Touch ªBACKº key of CONSULT-II until ªSELECT SYSTEMº
appears in order to return to User mode from Diagnosis mode.
11. Turn ignition switch ªOFFº, then turn off and disconnect
CONSULT-II, and disconnect both battery cables.
12. Repair the system as outlined by the ªRepair orderº in ªCON-
SULT-II Diagnostic Code Chartº, that corresponds to the self-
diagnostic result. For replacement procedure of component
parts, refer to RS-11.
13. After repairing the system, go to DIAGNOSTIC PROCEDURE
3, page RS-40 for final checking.
