Troubleshooting
Self-diagnostic Procedures
When the Malfunction Indicator Lamp {MlL) has been reported on, do the following:
'1. Connect the SCS short connecto. to Service Check Connector as shown. (The 2P Service Check Connector is
located under the dash on the passenger side of the car.) Turn the ignition switch on.
DATA LII{KCONNECTOR (3PI
NOTE:Do not attachjumper wire.
2. Note the Diagnostic Trouble Code (DTC): The MIL indicates I code by the length 8nd numbsr ot blinks. The MIL
can indicate multiple component problems by blinking separate codes, one after another. Codes 1 through Igre
indicated by individual shon blinks. Codes 1O through 43 are indicated by a series of long and shon blinks. Th€
number of long blinks equals the first digit, the number ot short blinks equals the second digit. Sometimes the
firsr blink is difficult to see; always count the blinks at least twice to verify the code.

How to Read Flowcharts
A flowchrrt is dasigned to be us€d fiom start to final repair. lt's like a map showing you the shortest distanco. But be-
ware: if you go off tho "map" anywhere but a "stop" symbol, you can easily get lost
l6rffil Desclibas the conditions or situation to start a troubleshooting flowchart.(bold tyDo)
|TeTiONl Asks you to do something; pedorm a test, set up a condition etc'
<:6Eei6io-fr\> Asks you about the result of an action, then sends you in the appropriste troubleshooting direction.
I-SJTFI The snd of a series ot actions and decisions, describes I tinal repair action and aomotimea diracts
(bold typel you to 8n garlier part of the tlowchart to confirm your repair'
NOTE:
a Tha tarm ,,lntormittgnt Failure" is used in these chans. lt simply means a system may have had a failur6, but it chocks
out OK !t this time. lf th6 Msltunction Indicator Lamp (MlL) on ihe dash does not come on, check for poor connections
or loose wires at all connectors rolated to the cilcuit that you are troubleshooting (see illustration b6low).
a Most ot tho troublashooting flowchans have you reset the Engine Control Module (ECM) and try to duplicate the Disg-
nostic Troubls Cod6 (DTC). lf the problem is intermittent and you c8n't duplicat€ the cod6, do not continus through
the flowchart, To do so will only rosult in confusion and, possibly, a ne€dlessly replaced ECM
a ,,opon,'and ,,short,, are common electrical terms. An open is a break in a wir6 or at a conn€ction. A short is an
accidontal connaction ot a wir€ to ground or to another wire. In simple electronics, this usually means som€thing won't
work at all. In complex electronics (like ECM's), this can sometimes mean something wolks, but not the way it's sup-
poSad to,
a il th6 olectricsl readings are not as specified when using the test harness, check the test harness connoctions bsfore
procooding.
