a The screens for "SELF-DIAG [CURRENTJ", "SELF-DIAG [PAST]" and "TROUBLE DlAG RECORD" share the same message. Follow the repair procedures in numerical order. Check whether a malfunction is eliminated each time a repair item is
finished, and when the malfunction is eliminated, further repair work is not required.
After repairing the system, touch "ERASE" to clear the memory and check with CONSULT again.
If both seat belt pre-tensioner systems on the driver seat and passenger seat have failed at the same time, only one of
the two failures is displayed first. The other failure is displayed after the first failure is repaired. For seat belt pre-tensioner
systems,
only
"SELF-DIAG [CURRENTJ" is displayed; "SELF-DIAG
[PASTJ"
and "TROUBLE DlAG RECORD" are not dis-
played.
