Diagnostic Codes Table    
Code and Description     Conditions which Generate this Code     System Response    
549-2 Throttle Lock Switch : Erratic, Intermittent, or Incorrect     The Electronic Control Module (ECM) detects an invalid signal from the throttle lock switch.     The code is logged. The ECM will disable the automatic control of engine speed through the throttle hold feature and the throttle lock feature.    
2770-3 Throttle Lock Resume/Decel Switch : Voltage Above Normal     Both contacts of the "throttle lock resume/decel switch"are in the open state.     The code is logged. The ECM will disable the automatic control of engine speed through the throttle hold feature and the throttle lock feature.    
2770-4 Throttle Lock Resume/Decel Switch : Voltage Below Normal     Both contacts of the "throttle lock resume/decel switch" are in the closed state.    
2771-3 Throttle Lock Set/Accel Switch : Voltage Above Normal     Both contacts of the "throttle lock set/accel switch" are in the open state.     The code is logged. The ECM will disable the automatic control of engine speed through the throttle hold feature and the throttle lock feature.    
2771-4 Throttle Lock Set/Accel Switch : Voltage Below Normal     Both contacts of the "throttle lock set/accel switch" are in the closed state.    The throttle lock feature is activated through the use of the throttle lock switch and the "throttle lock set/accel switch" in order to maintain a desired engine speed. The throttle lock switch is a three-position rocker switch that is used to select the mode of operation. The "throttle lock set/accel switch" is a two-position momentary rocker switch. This switch is for setting the engine speed and/or adjusting the engine speed. The throttle lock feature has the following three modes of operation:
Automatic mode
Manual mode
OFFAutomatic ModeDepress the throttle lock switch in the forward direction to the AUTO position in order to select the automatic mode. Use the throttle pedal to achieve the desired engine speed and then depress the "throttle lock set/accel switch" in the forward direction (SET/ACCEL) in order to set the desired engine speed.Acceleration - Moving the "throttle lock set/accel switch" in the forward direction (SET/ACCEL) will increase the desired engine speed. Momentarily bumping the "throttle lock set/accel switch" will increase the desired engine speed by 100 rpm. Holding the "throttle lock set/accel switch" for more than 250 milliseconds will increase the desired engine speed at a rate of 700 rpm per second. Moving the throttle pedal past the engine speed setpoint will increase the engine speed. Releasing the throttle pedal will allow the engine speed to return to the locked engine speed.Deceleration - Moving the "throttle lock resume/decel switch" (RESUME/DECEL) on the joystick will decrease the desired engine speed. Momentarily bumping the "throttle lock resume/decel switch" will decrease the desired engine speed by 100 rpm. Holding the "throttle lock resume/decel switch" for more than 250 milliseconds will decrease the desired engine speed at a rate of 700 rpm per second.Note: Actual engine speed may ramp at a slower rate than desired engine speed. The "throttle lock set/accel switch" and the "throttle lock resume/decel switch" control desired engine speed. For example, if you bump the "throttle lock set/accel switch" five times, desired engine speed will immediately increase by 500 rpm. Actual engine speed may not react quickly if the engine is under load.Automatic Mode ("Throttle Lock Kickout") - If the throttle lock feature is enabled and active, any of the following actions will cancel throttle lock.
Applying the service brake will suspend the selected engine speed and the engine will decelerate at a rate of 700 rpm per second until the engine speed matches the desired engine speed for the throttle pedal position.
After the throttle pedal has been released to less than 10 percent, depressing the throttle pedal to more than 25 percent will suspend the selected engine speed and the engine speed will change at a rate of 700 rpm per second until the engine speed matches the desired engine speed for the position of the throttle pedal.
The operator moves the throttle lock switch to the OFF position.The suspended engine speed may be resumed if none of the following actions has occurred:
The throttle lock switch is moved to the OFF position.
The keyswitch is turned to the OFF position.
The engine stalls.Manual ModeDepress the throttle lock switch in the backward direction to the MAN position in order to select the manual mode. Use the throttle pedal to achieve the desired engine speed and then depress the "throttle lock set/accel switch" in the forward direction (SET/ACCEL) in order to set the desired engine speed.Acceleration - Moving the "throttle lock set/accel switch" in the forward direction (SET/ACCEL) will increase the desired engine speed. Momentarily bumping the "throttle lock set/accel switch" will increase the desired engine speed by 100 rpm. Holding the "throttle lock set/accel switch" for more than 250 milliseconds will increase the desired engine speed at a rate of 700 rpm per second. Moving the throttle pedal past the engine speed setpoint will increase the engine speed. Releasing the throttle pedal will allow the engine speed to return to the locked engine speed.Deceleration - Moving the "throttle lock resume/decel switch" (RESUME/DECEL) on the joystick will decrease the desired engine speed. Momentarily bumping the "throttle lock resume/decel switch" will decrease the desired engine speed by 100 rpm. Holding the "throttle lock resume/decel switch" for more than 250 milliseconds will decrease the desired engine speed at a rate of 700 rpm per second. Note: Actual engine speed may ramp at a slower rate than desired engine speed. The "throttle lock set/accel switch" and the "throttle lock resume/decel switch" control desired engine speed. For example, if you bump the "throttle lock set/accel switch" five times, desired engine speed will immediately increase by 500 rpm.
