Fault Code 513: Clutch Release Solenoid 1 (C5) – Coarse Fill
J1939: SA 3 SPN 5616 FMI 0, 1, 3, 4, 5, 6, 7, 8, 10, 12, 16, 18
Overview
The Endurant HD transmission is equipped with solenoids to direct pneumatic flow to release and engage the clutch. The Clutch Release Solenoid 1 (CRS1) is energized by the Transmission Control Module (TCM) to direct vehicle supplied air pressure into the Linear Clutch Actuator (LCA) and release the clutch. The clutch control system requires four solenoids to control the clutch position – two clutch engage solenoids and two clutch release solenoids. The CRS1 quickly applies air pressure to the LCA and releases the clutch. The CRS1 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 CRS1. If a system failure is detected, the fault is set Active.
Conditions to Set Fault Code Active
FMI 0 – Data Valid But Above Normal (Most Severe): CRS1 low side current is greater than commanded current.
FMI 1 – Data Valid But Below Normal (Most Severe): CRS1 low side current is less than commanded current.
FMI 3 – Voltage Above Normal or Shorted High: CRS1 shorted to power for 2 seconds.
FMI 4 – Voltage Below Normal or Shorted Low: CRS1 commanded off and shorted to ground for 2 seconds.
FMI 5 – Current Below Normal or Open Circuit: CRS1 open circuit for 2 seconds.
FMI 6 – Current Above Normal or Shorted Circuit: CRS1 commanded on and shorted to ground.
FMI 7 – Mechanical System Not Responding: The LCA Position Sensor reports the clutch is released while the clutch control system is attempting to engage the clutch.
FMI 8 – Abnormal Frequency: CRS1 out of normal operating frequency.
FMI 10 – Abnormal Rate of Change: The clutch engage solenoid has been commanded on for a longer duty cycle than expected to maintain clutch engagement for 10 seconds.
FMI 12 – Bad Intelligent Device: CRS1 commanded on beyond expected duty cycle.
FMI 16 – Data Valid but Above Normal (Moderately Severe): CRS1 commanded on for longer than expected increasing solenoid temperature.
FMI 18 – Data Valid but Below Normal (Moderately Severe): CRS1 commanded on below expected voltage.
