REPAIR KIT 6V3000 - Caterpillar

This diagnostic code is recorded when VIMS electronic control module reads the signal from the trailer left brake oil temperature sensor and the frequency of the signal or pulse of the signal is not within an expected range. The sensor sends a PWM signal to the VIMS electronic control module. The possible causes of this diagnostic code are listed here:
The sensor has failed.
Intermittent connections or poor connections
The VIMS electronic control module has failed. This is unlikely.Note: The following diagnostic code procedure can create other related diagnostic codes. Perform the following procedure. Reconnect all harnesses. Then clear all the related diagnostic codes.Test Step 1. CHECK THE SENSOR.
Turn the disconnect switch and the key start switch to the ON position.
Ensure that the diagnostic code is active.
Disconnect the sensor from the machine harness. Expected Result:The diagnostic code has changed from CID 0655 FMI 08 to CID 0655 FMI 03.Results:
YES - The diagnostic code has changed from CID 0655 FMI 08 to CID 0655 FMI 03. The sensor has failed.Repair: Replace the sensor. Verify that the new sensor corrected this diagnostic code. The diagnostic code should NOT be active.STOP
NO - The diagnostic code CID 0655 FMI 08 remains active. The sensor is not the cause of the diagnostic code. proceed to test step 2.Test Step 2. CHECK FOR A SHORT IN THE MACHINE HARNESS.
The sensor remains disconnected from the machine harness.
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the J1 and J2 machine harness connectors from the VIMS electronic control module.
At the machine harness connector for the VIMS electronic control module, measure the resistance between the signal contact to all other J1 and J2 contacts. Expected Result:Each resistance measurement should be greater than 5000 ohms.Results:
YES - Each resistance measurement is greater than 5000 ohms. The harness is correct. The VIMS electronic control module has failed.Repair: It is unlikely that the VIMS electronic control module has failed. Exit this procedure and perform this diagnostic code procedure again. If the cause of the diagnostic code is not found, replace the VIMS electronic control module. Refer to the Testing and Adjusting, "Module - Replace" section. STOP
NO - The resistance is not greater than 5000 ohms for each measurement. The machine harness has failed. There is a short in the machine harness. The short is between the signal circuit and the circuit with the low resistance measurement. Repair: Repair the machine harness or replace the machine harness.STOP
