TROUBLESHOOTING HINTS
Hint 1:
If thenumber steppermotor steps increases to
100-120 steps or decreases to 0 step, the cause
maybe presumedtobemalfunctionofthe
Ordamaged or disconnected wiring
stepper moto
of the harness_
Hint 2:
Ifthenumberof steppermotorstepsdeviates
fromthe standard value even through the results
of the checking of the harness of the idle-speed
control servo and of the component itself indicate
noabnormalcondition,thecausemaybe
presumed to be one of the following
(1) Improperadjustmentofthestandardidling
speed.
(21Depossits adhered to the throttle valve_
(31 Leakage of air into the intake manifold from
gasket gap, etc.
(4) Incompletecombustionwithinthecylinder_
(Malfunctionofthespark plugs,the ignition
coil,the injectors, the compressionpressure
etc )
Проверка
Using Multi-use tester (MUT)

Wave Pattern Inspection Using an Analyzer Observation method
(1)Disconnectthe steppermotorconnector,andconnect
the special tool (test harness: MB998463) in between:
(2) Connect the analyzer special patterns pickup to the step
per motor-side connector terminal(red clip on the spe-
cial tool) , terminal(green clip) , terminal(black clip)
and terminal 0 (yellow clip) respectively
