Test Procedures - BRP Johnson J30TEL4SUA 2007 Service Manual

If the engine speed is over 3000 RPM, the over-
revolution caution control will be activated. The
engine speed will be automatically controlled by
ignition interruption and lowered to approximately
3000 RPM.
To cancel the overheat caution control, the cylin-
der wall temperature must be reduced to less than
158°F (70°C) and, at the same time, the engine
speed must be decreased to 1500 RPM or lower.

Test Procedures

Checking the Oil Pressure Switch
IMPORTANT:
Before checking the low oil pres-
sure caution circuit, make sure the engine oil
pressure is over 7 psi (49 kPa).
Remove the blue/yellow lead wire from the oil
pressure switch. Check for continuity between the
switch terminal and the engine body ground.
If the measurement is out of specification, replace
the oil pressure switch.
