ECM REPLACEMENT
General
Prior to replacing a suspected ECM, ensure that all
the recommendations in the general introduction
of this section have been followed.
IMPORTANT: When the ECM is replaced, the
tether cord cap(s) and the Closed Throttle must
be reprogrammed/reset. Refer to their specific
section for adjustment.
To allow transferring the previous recorded infor-
mation from the old ECM to the new one, use the
vehicle communication kit (VCK) with the B.U.D.S.
software. Use Replace ECM in the ECM menu.
Follow instructions provided by the help system.
NOTE: If the old ECM can still communicate, it
must be read inside B.U.D.S. prior to removing it
from the vehicle to carry vehicle information and
history to the new ECM.
ECM Replacement
Disconnect battery cables.
WARNING
Battery BLACK (-) cable must always be dis-
connected first and connected last.
