ENGINE AR-COMPLETE 3733834 - Caterpillar

Solution
Use the calibrations that are listed below in order to verify if there is a failure with the 198-8372 Position Sensor Gp (ROTARY) .Troubleshooting Information
Communicate failures of the parts that are listed above to Caterpillar Electronics Product Analyst at (309) 494-0744 when you begin troubleshooting the sensor. Also, the Caterpillar Electronics Product Analyst can be contacted at the following e-mail address: "West_Michael_J". This information will help Caterpillar better understand the reason that these sensors are being replaced. Please have the following information when you contact the Product Analyst.
VIMS data logger that contains the active fault code
Event summaries from Caterpillar Electronic Technician (Cat ET)
The service history of the truck body and body pivot pin may affect the data. Other factors that may affect the data include the following: The pivot pins have been replaced and/or serviced. The body has been serviced and/or replaced.
Record of any problems with the linkage assembly that connects the sensor to the body
Any other information that is pertinent in the troubleshooting of this problemCalibration Procedures
The calibration procedure must be performed when one or more of the following conditions occur:
A new truck is being assembled.
A new position sensor is installed.
The ECM is replaced.
The body is replaced.The position sensor is located near the pivot pin for the dump body. A lever is attached between the sensor and the dump body. When the dump body is raised or lowered, the lever rotates the sensor. This action changes the Pulse Width Modulation signal (PWM signal) that is sent to the Chassis Electronic Control Module (Chassis ECM). If the expected PWM signal does not occur, then the Chassis ECM generates an event code. The code is logged to the Vital Information Management System (VIMS).Do not attempt any procedure until you have read the information and you understand the information that is in this special instruction.Full Lower Calibration
Required Conditions
The following conditions must be met for 12 seconds:
The engine is running with no ground speed.
The payload is zero.
The hoist control lever must be in FLOAT mode.
The duty cycle output is within the range of 3 percent to 30 percent.Note: The recommended duty cycle output is within the range of 14 percent to 19 percent.When all of the conditions have been met for 12 seconds, the value of the calibration will be the average of the values that were recorded during that period of time. Expected Values
When the bed is fully lowered, the Chassis ECM expects a value that is greater than 1 percent PWM.If the expected PWM value is not obtained, then an FMI-04 will be logged. If this event occurs, then perform the ""Rod Adjustment"" in the ""Maintenance Procedures"" section. Tolerance Range
The standard range for the calibration limits is plus or minus 2 percent of the last calibration point. If the tolerance range is not exceeded, then the lower
