Description:

This diagnostic trouble code is generated if the control software detects that the second attempt to engage the range has failed. In its active state, this fault also generates the diagnostic trouble code for time-out when engaging the gear. The operator is prompted to engage the range again.

Reaction:

When this error is detected, the transmission may experience limited or no function as the range cannot be engaged.

Recommendations:

• Follow Operator Instructions:
  • Attempt to engage the range again as prompted by the control software.
• Inspect Transmission Mechanism:
  • Check the mechanical components of the transmission for signs of wear, damage, or misalignment that could be preventing engagement. Repair or replace any faulty components.
• Verify Solenoid Operation:
  • Ensure the Range B solenoid is functioning correctly. Test the solenoid and replace it if necessary.
• Check Hydraulic System:
  • Inspect the hydraulic system that controls the range engagement for any issues. Ensure there are no leaks and that the hydraulic pressure is within the specified range.
• Update Control Software:
  • Ensure the control software is up-to-date. Install the latest software updates from the manufacturer to improve performance and engagement reliability.

Note:

Regular maintenance of the transmission and its components is crucial for preventing engagement failures. Following the operator instructions and ensuring all systems are functioning correctly can help resolve this issue.
