HOW TOERASE SELF-DIAGNOSTIC RESULTS
(Malfunction codes)

1. Disconnect thecheck terminal fromground (ASSwarning
lamp willstay lit).
2. Within 12.5seconds, groundthecheck terminal 3times.
Each terminal groundmustlastmore than1second. The
ASS warning lampgoesoutafter theerase operation has
been completed.
3. Perform self-diagnosis again.RefertoSR-56. Onlythestart

HOW
TOREAD SELF-DIAGNOSTIC RESULTS(Malfunction codes)

• Determine thecode No.bycounting thenumber oftimes thewarning lampflashes onand off.
• When several malfunctions occuratone time, uptothree codenumbers canbestored; thelatest
malfunction willbeindicated first.
• The indication beginswiththestart code 12.After thatamaximum ofthree codenumbers appearin
the order ofthe latest onefirst. Theindication thenreturns tothe start code 12torepeat (theindi-
cation willstay onfor five minutes atthe most).
• The malfunction codechart isgiven onthe next page.
