Oil Pressure Warning Indicator Light (LED) Delay Unit Removal
- Remove the right middle fairing (See Middle Fairing Removal in the Frame chapter).
- Disconnect the connector [A] and remove the delay unit [B].

Oil Pressure Warning System Inspection
- Do the 1st step test.
Turn the ignition switch ON.
If the oil pressure warning indicator light (LED) [A] is lit, go to the 2nd step.
If the oil pressure warning indicator light (LED) is not lit, go to the 3rd step.

- Do the 2nd step test.
Check the oil pressure switch connections (See Switch Inspection).
If the oil pressure switch connections is good, go to the 4th step.
- Do the 3rd step test.
Disconnect the oil pressure switch lead [A] (See Oil Pressure) Switch Removal in the Engine Lubrication System chapter).
Ground the oil pressure switch lead to the engine, using an auxiliary wire [B].
Turn the ignition switch ON.
If the oil pressure warning indicator light (LED) is lit, check the oil pressure switch connections (See Switch Inspection).
If the oil pressure warning indicator light (LED) is not lit, check the oil pressure warning indicator light (LED) (see Meter Unit Inspection) and wiring (see wiring diagram in this section).
If the oil pressure warning indicator light (LED) and wiring are good, replace the delay unit (See Oil Pressure) Warning Indicator Light (LED) Delay Unit Removal).

- Do the 4th step test.
Disconnect the oil pressure switch lead [A] (See Oil Pressure) Switch Removal in the Engine Lubrication System chapter).
Ground the oil pressure switch lead to the engine, using an auxiliary wire [B].
Turn the ignition switch ON.
The oil pressure warning indicator light (LED) should be lit.
Disconnect the auxiliary lead from the engine.
If the oil pressure warning indicator light (LED) goes off, go to the 5th step.
If the oil pressure warning indicator light (LED) does not go off, replace the delay unit (See Oil Pressure) Warning Indicator Light (LED) Delay Unit Removal).
- Do the 5th step test.
Turn the ignition switch ON.
Ground the oil pressure switch lead to the engine, then the oil pressure warning indicator light (LED) should be lit with a delay.
Measure the this delay time from grounding of the switch lead to lighting of the warning indicator light (LED).
Lighting Delay Time
Standard: About 3 seconds
If the lighting delay time is the standard, inspect the oil pressure (See Oil Pressure Measurement in the Engine Lubrication System chapter).
If the lighting delay time is out of the standard too far, replace the delay unit (See Oil Pressure) Warning Indicator Light (LED) Delay Unit Removal).
