The implements will move in small increments when the arrow key for the desired direction is pressed. The corresponding solenoid will respond to the arrow key with a predetermined pulse time. The movement of the implement will be affected by the speed of the engine. The controls of the implement are not used for the limp home mode. The "OK" key is pressed after the limp home mode is no longer needed. The operation of the "Limp Home Mode" will take priority over all other functions. A diagnostic code will not disable the "Limp Home Mode". All other implement functions will be available through normal operations of the blade control handle or ripper control handle.Towed Scraper Application
Note: The wiring and the hydraulic configuration for this option are not supplied. The towed scraper application provides a modified ripper hydraulic control system in order to operate the towed scraper bowl. The configuration is supported in the electronic software. The configuration requires a minor modification of the electrical system in order to make use of the configuration.

Electronic Control Module (ECM)The hydraulic system should be configured by the customer in order to provide the bowl raise/lower function on the thumb lever of the ripper control. The hydraulics should be configured to provide the bowl ejector in/out function on the finger lever of the ripper control. The configuration would use the ports of the ripper raise/lower function in order to provide the primary hydraulic power to the scraper bowl. In addition, this configuration would use the driver of the auxiliary solenoid in order to control an additional electrohydraulic solenoid. The electrohydraulic solenoid will switch the bowl raise/lower function to the bowl ejector in/out function. During the command for the finger lever from the ripper control, the implement electronic control will energize a driver for an auxiliary solenoid. The electrical connector for the auxiliary solenoid driver is not connected to the machine wiring. The customer must wire the auxiliary solenoid. The signal to the solenoid is wired to pin 61 on the connector "J1" on the implement ECM. The wiring and the hydraulic configuration for the towed scraper application are not supplied because of the wide range of possible hydraulic configurations. Give careful consideration when you adapt the scraper bowl in order to work with the towed scraper application. The following considerations should be made:
The driver for the auxiliary solenoid has normal Caterpillar diagnostics. The diagnostics depend on using a specific type of coil for the solenoid valve. The diagnostics have been tested for a 145-1144 Coil and a 156-6173 Coil. Another coil may cause a false diagnostic. A coil with a resistance between 7 ohms and 9 ohms is likely to function with the diagnostics. The electrical diagnostics perform the following checks: open circuits, short circuit to ground and short circuit to the battery.
The driver of the solenoid will supply a maximum of 1 amp when this solenoid is on. The auxiliary solenoid driver is
