MODE
CAUTION
Do not perform Power Test if engine temperature is above
normal operating temperature. However, the engine
should be at operating temperature before performing
the Power Test.
NOTE
The vehicle identification number of Test G01 must have
been entered prior to the Power Test. This will prevent
an error message (E004) and unsuccessful completion of
the Power Test. If you do not have a vehicle ID number,
but the number of cylinders was entered in G01, use Test
12 for Power Test instead of Test 13. When using Test 12,
the first number to appear on the display is the signal
to release the accelerator.

• Dial 12 into TEST SELECT and press TEST.
• Wait for prompting message CIP to appear.

POWER TEST

NOTE
• About 40 seconds after start-
ing test, engine will accelerate
slightly and then stop. The
engine will run rough and may
backfire. This is normal.
• If LO message appears on
VTM display, then vehicle has
failed Power Test. This mes-
sage appears when the vehicle
cannot maintain a sufficient
power level long enough to
complete the test.
• Two numbers will appear on
the VTM display. These are
the test results. The first
number is the interrupt speed
in RPM. This number will go
away after a few seconds.
The second number is the
coast down deceleration in
RPM/SEC. This number will
remain on display.
