Fault Code 514: Clutch Release Solenoid 2 (C6) – Fine Fill
J1939: SA 3 SPN 5617 FMI 0, 1, 3, 4, 5, 6, 8, 10, 12, 16, 18
Overview
The Endurant XD Series transmissions are equipped with solenoid valves that direct vehicle Supply Air to and from the Linear Clutch Actuator (LCA) to control clutch position. The clutch control system includes four solenoid valves – two for engagement (Vent) and two for disengagement (Fill).
The Clutch Release Solenoid 2 (CRS2) valve is energized by the Transmission Control Module (TCM) to direct Supply Air to the LCA, disengaging the clutch. The CRS2 valve is located in the Mechatronic Transmission Module (MTM) and connected to the TCM at the 74-Way Transmission Harness Connector.
Detection
The TCM monitors the CRS2 circuit. If a circuit or system failure is detected, the fault is set Active.
Conditions to Set Fault Code Active
FMI 0 – Data Valid But Above Normal (Most Severe): CRS2 Low-Side Current value greater than commanded current for 1 second.
FMI 1 – Data Valid But Below Normal (Most Severe): CRS2 Low-Side Current value less than commanded current for 1 second.
FMI 3 – Voltage Above Normal or Shorted High: CRS2 circuit shorted to power for 2 seconds after CRS2 commanded off.
FMI 4 – Voltage Below Normal or Shorted Low: CRS2 circuit shorted to ground for 2 seconds after CRS2 commanded off.
FMI 5 – Current Below Normal or Open Circuit: CRS2 circuit open for 2 seconds after CRS2 commanded off.
FMI 6 – Current Above Normal or Shorted Circuit: CRS2 circuit shorted to ground for 2 seconds after CRS2 commanded on.
FMI 8 – Abnormal Frequency: CRS2 signal frequency out of range for 1 second.
FMI 10 – Abnormal Rate of Change: Clutch Engage Solenoid commanded on longer than expected to maintain clutch engagement for 10 seconds.
FMI 12 – Bad Intelligent Device: TCM has detected an internal processing error.
FMI 16 – Data Valid but Above Normal (Moderately Severe): CRS2 commanded on longer than expected increasing solenoid temperature.
FMI 18 – Data Valid but Below Normal (Moderately Severe): CRS2 circuit voltage lower than expected for 1 second after CRS2 commanded on.

Fault Code 514 Troubleshooting
Set vehicle parking brake and chock wheels.
Record transmission fault codes, FMIs, occurrences, and timestamps from Service Activity Report created during the Diagnostic Procedure.
If Fault Code 514 FMI 0, 1, 3, 4, 5, 6, 8, 16, 18 is Active or Inactive, Go to Step B
If Fault Code 514 FMI 10 is Active or Inactive, Go to Step E
If Fault Code 514 FMI 12 is Active or Inactive, Contact Eaton Cummins Automated Transmission Technologies for further diagnostic instructions. For Help Line phone numbers, go to Contact Information. Go to Step V
Key off.
Remove TCM from MTM with 20-Way TCM Vehicle Harness Connector and 20-Way TCM Body Harness Connector connected.
Inspect TCM side of the 74-Way Transmission Harness Connector, verify connector is free from contamination and corrosion; terminals are not bent, spread or loose; and there is no damage to connector body.
Inspect TCM Seal, verify seal is properly installed and not damaged.
If contamination or damage is found to TCM side of 74-Way Transmission Harness Connector, replace Transmission Control Module (TCM) and Mechatronic Transmission Module (MTM). Go to Step V
Note: MTM removal and installation requires transmission to be removed from vehicle. Reference Endurant XD Service Manual TRSM0960, Transmission Removal Service Procedure.
If no contamination or damage is found, Go to Step C
Key off.
Connect Eaton Breakout Box with 74-Way Eaton Diagnostic Adapter to MTM side of 74-Way Transmission Harness Connector.
Measure resistance at Eaton Breakout Box between Pin 18 and Pin 19. Record reading in table.
Measure resistance at Eaton Breakout Box between Pin 19 and Ground (TCM mounting stud). Record reading in table.
Compare reading(s) in table.
If readings are in range, Go to Step D
If readings are out of range, replace Mechatronic Transmission Module (MTM). Go to Step V
Note: MTM removal and installation requires transmission be removed from vehicle. Reference Endurant XD Service Manual TRSM0960, Transmission Removal Service Procedure.
| Pins | Range | Reading(s) |
|---|---|---|
| 18 to 19 | 3.4–5.5 Ohms | |
| 19 to ground (TCM mounting stud) | Open Circuit (OL) |
