If no malfunction is detected on ªSELF-DIAG [CURRENT]º even
though malfunction is detected in ªSRS Operation Checkº, check
the battery voltage.
If the battery voltage is less than 9V, charge the battery. Then go
to DIAGNOSTIC PROCEDURE 3, page RS-42.
If the battery voltage is OK, go to DIAGNOSTIC PROCEDURE 4,
page RS-44, to diagnose the following cases:
