QUESTIONS
Got a question for our Tech Corner
expert? Just jot it down on a paper towel
or a lightly soiled shop rag and send it to
us at VETTE magazine, Attn: Technically
Speaking, 18 2 1 E. Dyer Rd., Suite 150 ,
Santa Ana, CA 9270 5. Alternatively, you
can submit your question via the Web, by
emailing it to vette@enthusiastnetwork.
com. Be sure to put “Technically
Speaking” in the subject line.the BPMV. The BPMV has been known to
fail, but this is not common. This unit can
be checked by measuring the resistance
between each pump motor control circuit
and the housing of the BPMV.
The EBCM has six T-20 Torx screws con-
necting it to the BPMV.
Cold-solder joints are quite common in
ABS/traction control modules, remote key-
less entry fobs, electronic climate-control
units, digital dashes and the seat control
module. We have covered repairing cold-
solder joints in the past on digital dashes
and seat-control modules.
Rick, if you or any of the other readers
are interested let me know and we can
go through repairing cold-solder joints in
the EBCM and checking the BPMV pump
motor. I hope this helps and thanks for
the question. VETTE
If you have
had any
electrical
problems on
a Corvette I
am sure you
are aware
that Cor-
vettes have
ground-
ing issues. There is no difference with
this problem, check the black wire with
an eyelet on the driver-side framerail
just in front of the alternator. There will
also be a small black box attached at this
grounding point so be sure to inspect
these components for corrosion and
a tight connection. This eyelet ground
being loose or corroded causes quite a
few problems with the EBCM. You may
find your problem here.
