Schematic of the 10 VDC Sensor Supply
This diagnostic code is associated with the 10 VDC sensor power supply of the Brake Electronic Control Module (ECM). The diagnostic code is activated even when no components are connected to the 10 VDC supply.The CID 1482 FMI 04 diagnostic code is activated when the ECM detects a below normal voltage of the 10 VDC power supply circuit.The following conditions could cause this diagnostic code:
The power supply circuit is shorted to a ground source.
The Brake ECM has failed. A failure of the ECM is unlikely.Note: The following test procedure may create other diagnostic codes. Clear the diagnostic codes when the problem has been corrected. Verify that the CID 1482 FMI 04 diagnostic code is active before performing this procedure.Test Step 1. CHECK THE STATUS OF THE DIAGNOSTIC CODE
Perform the following:
Visually inspect the harness connectors.
Clean the contacts of the harness connectors.
Visually inspect the insulation of the wires for damage that is caused by excessive heat, corrosion, or chafing.
Reconnect all harness connectors. Verify the following:
Connectors are fully seated.
The clips for each connector are fastened securely.
Use the Cat Electronic Technician (Cat ET) service tool to perform a wiggle test on the machine wiring harness. The wiggle test can detect intermittent shorts or opens in the machine wiring harness.
Turn the disconnect switch and the
