Section 07 ENGINE MANAGEMENT (DI)
Subsection 02 (COMPONENT INSPECTION AND ADJUSTMENT)
Ensure the throttle body plate stop lever rests
against its stopper. Open throttle approximately
one quarter then quickly release. Repeat 2 - 3
times to settle throttle plate. If stopper does not
rest against its stop lever, perform throttle cable
adjustment. Refer to THROTTLE BODY in AIR IN-
DUCTION SYSTEM above.
Push the Reset button in the Setting tab of
B.U.D.S.
NOTE: There is no idle speed adjustment to per-
form. The MPEM takes care of that. If TPS are
not within the allowed range while resetting the
closed TPS, the MPEM will generate a fault code
and will not accept the setting. To solve that, per-
form the Validating TPS Synchronization in the
MPEM REPLACEMENT section above.
Start engine and make sure it operates normally
through its full engine RPM range. If fault codes
appear, refer to DI SYSTEM FAULT CODES in DI-
AGNOSTIC PROCEDURES section for more infor-
mation.

Check for RPM display at the information center
while cranking engine (first ensure information
center is in tachometer mode). If i
tdisplaysap-
proximately 300 RPM, the CPS cir
cuitry is proper-
ly working.
Otherwise, validate the information center is
working by activating the tachometer using the
software B.U.D.S. under Activation (first ensure
information center is in tachometer mode). If
it does not display 3000 RPM, the information
center may be faulty and needs to be tested.
If the information center correctly displayed
3000 RPM, perform the following tests.
Take into account that a CPS fault can be trig-
gered by bent or missing encoder wheel teeth.
Check the teeth condition. Also, bad connections
in magneto connector could generate electrical
noise that would make you wrongly think the CPS
is faulty. Check terminals and wires.
Encoder Wheel Inspection
To check the encoder wheel for bent teeth, pro-
ceed as follows.
Remove magneto cover. Refer to MAGNETO
SYSTEM in ENGINE section.
Install a dial indicator on crankcase. Position
the gauge on a tooth and set it to zero (0). Ro-
tate flywheel and check needle movement. The
maximum allowed difference between teeth is
0.15 mm (.006 in). Otherwise, straighten the
tooth or replace the encoder wheel.
