Description:

This error code is triggered when the C1 clutch fails to engage due to excessive carrier speed, indicating a possible clutch enable pressure control problem. This fault automatically causes PTI 000630.13 and PTI 000630.14 to be generated. If PTI 524230.05 (clutch enable solenoid circuit fault) is stored or active, it should be diagnosed first.

Reaction:

The control unit commands the equipment to enter Park mode, which is recoverable.

Recommendations:

• Diagnose Related DTC:
  • If PTI 524230.05 is present, perform diagnosis and resolve that issue first.
• Inspect Clutch Enable Pressure:
  • Check the clutch enable pressure to ensure it is within the specified range.
  • Inspect for any leaks or blockages in the hydraulic system.
• Evaluate Clutch Components:
  • Verify that the C1 clutch is engaging and disengaging correctly.
  • Inspect for any wear or damage to the clutch components.
• Test Speed Sensors:
  • Ensure the speed sensors for the carrier are accurate and functioning correctly.
  • Replace any faulty sensors.

Note:

Addressing clutch engagement issues promptly is essential to prevent further damage and ensure reliable operation of the transmission system.
