Before starting the ECM
removal, disconnect
the negative battery lead from the battery. Remove the engine cover, then
remove the six screws securing the carpeted trim panel
from the right side of the engine bay. Some cars may be
missing one or more screws. |
Carefully remove the trim
panel by pulling it sideways then lifting slightly
upwards. |
Locate the two nuts, each securing one side of the ECM to
its bracket (yellow arrow). Loosen, but do not remove the
nuts from their studs. If the ECM is to be removed from
the car, squeeze the connectors as indicated by the green
arrows and wiggle all four of the connectors free. Lift
the ECM upwards to remove it.
|
Locate the access panel on
the bottom of the ECM and remove the four screws using a
1/4" nutdriver. If the ECM has never been serviced,
there will be one or two pieces of anti-tamper tape along
the edges. Slit at least one piece to gain access.
|
The memcal is the blue
object pictured above. To remove it, press down on the
latches as indicated above... |
As the latches move
outwards, the memcal will pop out of its socket. |
When reinstalling the
memcal, note the small bump, or key, along one edge of
the socket. |
Locate the corresponding
notch in the socket. Carefully position the memcal above
the socket and guide it into position. Push down firmly
and evenly until the latches click into place. Reinstall
the access panel and its four screws. |
Reinstall the ECM into the
car, being careful not to dislodge the mounting
studs/nuts. The flat washers should be fitted between the
mounting bracket and the nuts. Reconnect the four plugs,
noting that they are color coded as shown above.
Carefully reinstall the trim panel, being sure not to
tighten any of the screws until all of them have been
started. Reconnect the battery.
