HCC 001638.02 – HCC Calibration Fault/Hydraulic Oil Temperature Low

HCC 001638.02 (HCC 1638.02)

Code: 001638.02

Shortcode: 1638.02

Description:

This error code is generated when the Hitch Control Unit (HCC) is calibrated with the hydraulic oil temperature below 50°C (122°F). Proper calibration requires the hydraulic oil to be within a specific temperature range.

Reaction:

This error results in an indicator or alarm only, without disabling any functions.

Recommendations:

  • Warm Up Hydraulic System:
    • Ensure the hydraulic system is adequately warmed up and the oil temperature is above 50°C (122°F) before performing calibration.
  • Recalibrate HCC:
    • Repeat the calibration process with the hydraulic oil at the correct temperature.
  • Operator/Technician Training:
    • Provide training to operators and technicians on the importance of temperature conditions during calibration.

Note:

Accurate calibration of the HCC is critical for proper operation. Always perform calibration procedures with the hydraulic oil at the recommended temperature.
