HOW TOERASE DIAGNOSTIC TESTMODE II(Self-diagnostic results)

The diagnostic troublecodecanbeerased fromthebackup memory inthe ECM when thediagnostic
test mode ischanged fromDiagnostic TestMode IIto Diagnostic TestMode
I.
(Refer to"HOW TO
SWITCH DIAGNOSTIC TESTMODES" onprevious page.)

• If
the MIL blinks or"NATS MALFUNCTION" isdisplayed on
"SELF-OIAG RESULTS"screen,perform self-diagnostic
results modewithCONSULT usingNATS program card
(NATS-E940). RefertoEL section.
• Confirm noself-diagnostic resultsofNATS isdisplayed
