S10 PICKUP , NOT BLAZER S10- , NO ENGINE TOLD
NO DRIVE LINE TOLD.! NO VIN TOLD.
ENGINE RUNS FINE?
DRIVES FINE AND ALL OTHER THINGS WORK
THIS IS ALWAY SQUESTION 1 FOR ANY ELECTRIC FAILURE.
4l60E TRANSMISSION? OR STICK SHIFT, iT MATTERS TOO.
THE 4L60 E HAS VSS VEH, SPEEDS SENSOR ON THE TAIL SHAFT OF THE BOX..
no speedo cables here. this year.
the cluster has 1 fuse, Marked
INST-lps if blown the much of the cluster dies. means insturment lamps(LPS)
the question really is , all fuses good.
and if automatic trans
does the VSS go to the TCM (so it can shift right) then the TCM tells the ECU speed too. then it sense speed data to the cluster.
sadly the scans of the old paper book , are blurry and 100 pages long, i refuse to read all of those for all engines there
or transmissions not told.
NO FUSE JUST FOR IT.!!
1992
IS THE SPEEDO ONLY DEAD?
AND ALL OTHER CLUSTER THINGS WORK>? OR NOT.
oil gauge, fuel ,voltage meter, and odom? ,eng. temp?
ALL FUSES GOOD, IS FIRST. JUST CHECK THEM ALL NOT WORRY WHICH IS WHICH.
SPEEDO DEAD, OR BOUNCES OR STUCK HIGH. WHAT?
ODOMETER DEAD"MILES) DEAD? OR WHAT?
ING fuse must be good , goes to cluster too.
the book, deep looking shows
DRAC
vehicle speed sensor buffer;.
here it is, and it drives the cluster directly
so is sensor ,wiring or the buffer bad.
the signals are very weak so the board here is a Ampifier
it states vss to ecm, tcm and cluster.
so if the ECM cans show the VSS dead we know
the DRAC is bad or the sensor left hear is dead.
the red circle below is cluster INPUT VSS.
CHECK ALL FUSES. i CAN'T
