above, turn ignition switch ªOFFº to reset from Diagnosis mode
to User mode and to erase the memory of the malfunction.
Then go to step 6.
If ªAIR BAGº 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-48, and repair mal-
functioning part completely.
6. Turn ignition switch ªONº. ªAIR BAGº warning lamp operates in
User mode. Compare ªAIR BAGº warning lamp operation to
the chart below.
NOTE:
If switching Diagnosis mode to User mode is required while mal-
function is being detected, by turning ignition switch as follows:
1) Turn ignition switch ªONº.
2) After ªAIR BAGº warning lamp lights for 7 seconds, turn igni-
tion switch ªOFFº within 1 second.
3) Wait more than 3 seconds.
