warning lamp — Diagnosis mode
NOTE:
SRS will not enter Diagnosis mode if no malfunction is
detected in User mode.
1. Turn ignition switch “ON”.
2. After “AIR BAG” warning lamp lights for 7 seconds, turn igni-
tion switch “OFF” within 1 second.
3. Wait more than 3 seconds.
4. Repeat steps 1 to 3 three times.
5. Turn ignition switch “ON”.
SRS is now in Diagnosis mode.
6. “AIR BAG” warning lamp operates in Diagnosis mode as fol-
lows:
NOTE:
If SRS does not enter Diagnosis mode even though malfunction is
detected in User mode, check the battery voltage.
If the battery voltage is less than 9V, charge the battery. Then go
to DIAGNOSTIC PROCEDURE 7, page RS-65.
If the battery voltage is OK, replace the diagnosis sensor unit.

NOTE:
When diagnosis sensor unit is replaced with new one, “AIR BAG”
warning lamp will operate in User mode. Checking “AIR BAG”
warning lamp operation in Diagnosis mode is not required. Go to
step 6.
5. If “AIR BAG” warning lamp operates as shown in No. 1 in chart
above, turn ignition switch “OFF” to reset from Diagnosis mode
to User mode and to erase the memory of the malfunction.
Then go to step 6.
If “AIR BAG” warning lamp operates as shown in No. 2 or No.
3 in chart above, the malfunctioning part is not repaired
completely, or another malfunctioning part is detected. Go to
DIAGNOSTIC PROCEDURE 6, page RS-60, and repair mal-
functioning part completely.
6. Turn ignition switch “ON”. “AIR BAG” warning lamp operates in
User mode. Compare “AIR BAG” warning lamp operation to
the chart below.
NOTE:
When a malfunction is detected, switch from Diagnosis mode to
user mode by turning the ignition switch as follows:
1) Turn ignition switch “ON”.
2) After “AIR BAG” warning lamp lights for 7 seconds, turn igni-
tion switch “OFF” within 1 second.
3) Wait more than 3 seconds.
4) Repeat steps 1 to 3 three times.
5) Turn ignition switch “ON”.
