Intermittent Failures
The t e r m " i n t e r m i t t e n t f a i l u r e " means a system may
have had a failure, but it checks OK now. If the IMA
system indicator light on the dash does not c o m e on,
check for poor connections or loose w i r e s at all
connectors related to the circuit y o u are
troubleshooting.
Opens and Shorts
" O p e n " and " S h o r t " are c o m m o n electrical terms. A n
open is a break in a wire or at a connection. A short is
an accidental connection of a w i r e to g r o u n d or to
another w i r e . In simple electronics, this usually means
s o m e t h i n g w o n ' t w o r k at all. W i t h c o m p l e x electronics
such as the M C M , this can mean s o m e t h i n g works, but
not the w a y it's supposed to.
How to Use the HDS to Check for DTCs
If the IMA system indicator has come on
1. Start the engine and check the IMA system
indicator (A).
2. If the IMA system indicator stays o n , turn the
ignition switch OFF, then connect the HDS to the
data link connector (DLC) (A) located under the
driver's side of the dashboard.
3. Turn the ignition switch ON (II).
4. Select I M A SYSTEM on the HDS.
5. Check the diagnostic trouble code (DTC) and note it.
Also check the freeze data. Refer to the DTC
t r o u b l e s h o o t i n g and begin the appropriate
t r o u b l e s h o o t i n g procedure.
NOTE: For specific operations, refer to the user's
manual that came w i t h the HDS.
If you can't duplicate the DTC
Some of the troubleshooting requires y o u to reset the
M C M and try to duplicate the DTC. If the p r o b l e m is
intermittent and you can't duplicate the code, do not
continue t h r o u g h the procedure. To do so w i l l only
result in confusion and, possibly, a needlessly replaced
M C M .
