method
1
Oil pressure dropped
Keep the snow mobile horizontal and then measure
the oil pressure after the sufficient warm-up, and
check that the value is 25 kpa or more.
2
Oil pressure switch lead-short circuit
detected.
It measures between engine earths from the oil
pressure switch connector (Yellow/Green) with the
circuit tester.
NOTE:
Disconnect is ECU coupler.
3
Defective oil pressure switch
After 1 minute has passed since the engine start,
measure the resistance between the oil pressure
switch and switch body with a circuit tester, and it
will be OK if the result showed
∞
.
