ABS Problem with my 2000 Buick Century
Engine size = 3.8
dash lights =
abs light is on
GM Computer codes c1218
GM tech = JK
question = How do I go about fixing my ABS with the code c1218. Can I do it
myself.
/
Buick Century 1999
3800 V6
dash lights = Service Engine Soon
codes = two codes came up when AAMCO checked ... I was told one was
engine misfire and one was transmission slip
work done prior = No work was done ... The light was reset but came
back on again after a couple of weeks ...
Tech = JK
question = Is it safe to drive this car with the Service Engine Soon
light on ... I took it to AAMCO which does free computer analysis ... The
tech said he got two codes which he described as engine misfire and
transmission "slip" ... He said the only thing he could do was "rebuild"
the transmission for $2,000+ ...If I take this car to Buick dealer they
will charge me another $100 just to hook up to the computer ... The
car will not pass DC inspection with the check engine light on ... Any
suggestions? Thanks







JK:
It would help to know the exact code numbers.
Any misfire has the potential to damage the catalytic converter. The misfire needs to
be repaired,.
The
trans. code may or may not require an overhaul, again, it depends on the exact
code for me to give any help on this matter.
Either way, the only way to stop a code from returning is to have the problems
repaired.

ABS code c1218 is described as Pump Motor Circuit Shorted to Voltage. First
things first- check the fuses. There are 2.  Labeled ABS (10 amp), and ABS
MAXIFUSE(60 amp).The first is in the fuse block on the rt. side of the dash at
the door opening, the other is in the under hood fuse block. If the fuses are
good, then a probable cause is a faulty ABS brake pressure modulator valve
assembly (BPMV).  There are a few tests that would need to be done to test for
this expensive part being faulty.
