PIN 9D5528 - Caterpillar

Implement ECM
This test is reserved for identifying conditions related to the programming of the ECM or a signal failure. In this instance the ECM is receiving information that is erratic, intermittent, or incorrect. A failure of the internal program of the ECM is associated with the test as well. The fault messages displayed in Cat®ET or via the operator monitor include "programmed parameter fault" or some type of machine monitoring failure.The following diagnostic trouble codes (DTC's) are associated with the configuration parameters for the Implement ECM.
Table 1
Implement ECM (MID 82)
DTC Description System Response
268-2 Programmed Parameter Fault : Data Erratic, Intermittent, or Incorrect The Implement ECM has determined that a configuration parameter is not programmed. The ECM will display the parameter causing the problem via Cat® ET.
2183-13 Payload Monitoring System : Calibration Required System must be calibrated before operating. Possible Causes for a DTC 268-2 are:
A configuration parameter on the ECM is blank or invalid.The Payload Load Control System (PCS) provides an accurate weight of the material that is loaded into the bucket of the wheel loader. The PCS is controlled by the Implement ECM. The PCS operator commands to the Monitoring System Display are communicated via the Cat® Data Link. The Implement ECM acts on the PCS command accordingly.Possible Causes for a DTC 2183-13 are:
The Implement ECM has never been calibrated.
The Implement ECM has lost all of the permanent information on the setup of the machine.Diagnostic Trouble Code Procedure
Table 2
Troubleshooting Test Steps Values Results
1. Verify The Configuration Of The Implement ECM
A. Use Cat®ET to view the diagnostic code. The parameter causing the code will be displayed. Reset the configuration for the identified parameter as appropriate for the machine.
The Implement ECM has no blank or invalid configurations. OK - The Implement ECM has no blank or invalid configurations.
Verify that the new configuration has corrected the problem before attempting to operate the machine.
STOP
NOT OK - The Implement ECM has blank or invalid configurations.
Repair: Repeat this procedure.
If the diagnostic code remains active or repeatedly activated and no cause can be found, flash the ECM with the latest version of software. Ensure that you have the latest version of software for your specific machine and ECM. Refer to the Troubleshooting, " ECM Software - Install " section of this manual for the correct procedure.
If the problem is still present after flashing the latest software to the ECM, contact the technical communicator for a possible consultation with Caterpillar.

PCS Store Switch

Illustration of the Payload Control System Store Switch electrical connections
The PCS Store Switch is installed on the machines with the Payload Control System attachment.When the Payload Control System is active, the PCS Store Switch is used to store the current bucket information in the Implement ECM memory. The switch is also used to reset the current bucket weight to zero.When the PCS Store Switch is pressed, the ECM receives a signal that the input circuit is grounded. The Implement ECM response will depend on the PCS mode
