Implement Lockout Switch | |
The implement lockout switch is designed to de-energize the implement lockout solenoid. The ECM will provide power to the solenoid through the implement lockout switch. The circuit is open and the implement lockout solenoid is de-energized, when the switch is placed in the LOCKED position. The switch should be in the LOCKED position before any of the following conditions occur:
- The operator exits the machine.
- The machine is serviced.
- The machine is left unattended.
The switch affects the system in the following manner:
LOCKED - The implement lockout solenoid is de-energized. The implement system is no longer operable.
UNLOCKED - The implement lockout solenoid is energized. The implement system is enabled.
The switch is a single-pole rocker switch. The switch has a normally closed contact and a normally open contact. One contact connects to the switch input of the ECM. The other contact connects to the feedback input of the ECM and to the lockout solenoid. The pole of the switch connects to the output of the ECM for the implement lockout solenoid. The ECM can always determine whether the switch is in the LOCKED position or the UNLOCKED position. The two input circuits are used for diagnostic purposes. The ECM will detect a failure in the circuit if the two circuits of the switch are ever in the same state. The ECM will also record a diagnostic code. The diagnostic code that is associated with the implement lockout switch is CID 0490.
