[INTERMITTENT TROUBLES]
<Vehicle equipped with monitor coupler>
There are cases where output of diagnostic output terminal
and / or malfunction indicator lamp indicate a diagnostic trouble
code representing a trouble which occurred only temporarily and
has gone. In such case, it may occur that good parts are replaced
unnecessarily. To prevent such accident, be sure to follow instruc-
tions given below when checking by using “Diagnostic Flow
Table”.
* When trouble can be identified, it is not an intermittent one:
Check coil antenna, ignition key, wires and each connection
and if they are all in good condition, substitute a known-good
ECM / PCM and recheck.
* When trouble can not be identified but output of diagnostic out-
put terminal and / or malfunction indicator lamp indicate a
trouble code:
Diagnose trouble by using that code No. and if ignition key, coil
antenna, wires and each connection are all in good condition,
turn OFF ignition switch and then ON.
Then check what malfunction indicator lamp and / or output of diag-
nostic output terminal indicate.
Only when they indicate trouble code again, substitute a known-
good ECM / PCM or Immobilizer Control Module and check again.
If they indicate not trouble code but normal code, it means that an
intermittent trouble did occur and has gone. In this case, check
wires and connections carefully again.
