CHECKING CALIBRATION
PROGRAM
Using VCK (Vehicle Communication Kit)
All Models
The VCK (P/N 529 035 981 ) can be used with the
B.U.D.S. software to check the calibration. De-
tailed information about the B.U.D.S. software and
its usage is available under its Help section.
Using MPEM Programmer
All Models except SDI
Calibration can also be checked using the MPEM
programmer (P/N 529 035 878).
CAUTION: Do not interchange MPEM from a
model to an other. Even if the P/N stamped
on the MPEM is the same, calibration program
may be different. When ordering a new MPEM
always refer to appropriate model parts cata-
log. The service P/N published in parts cata-
logs are the ones with the good calibration pro-
gram according to model.
With Engine Running
If the below mentioned tool is not available start
engine. Turn on programmer then enter pass-
word.
Increase engine speed to 2000 - 2500 RPM then
follow the same procedure as WITH ENGINE
STOPPED.
CAUTION: Engine must run till the end of the
procedure.
When data are being transferred, you must rev
the engine at 2000 - 2500 RPM and make sure
connection between programmer and vehicle is
good.
IMPORTANT: In following procedure each time ←
Trs symbol appears, make sure to rev engine be-
tween 2000 and 2500 RPM.
Engine will misfire while vehicle information is be-
ing transferred from MPEM to programmer. If en-
gine stalls, restart it, keep engine speed at 2000 -
2500 RPM and select no. 3 VEHICLE INFO again.
With Engine Stopped
Connect 9-volt adaptor (P/N 529 035 675) to sup-
ply cable (P/N 529 035 869) and supply cable to
diagnostic connector, located on right side of the
vehicle.
