ACU 524212.04 – Low Voltage in Rear Hitch Control Lever Sensor

ACU 524212.04 (ACU )

Code: 524212.04

Shortcode:

Description:

Error code ACU 524212.04 indicates that the voltage in the rear hitch control lever sensor circuit is below the expected threshold. Low voltage may be caused by issues such as weak battery performance, poor electrical connections, or a failing sensor, all of which could compromise the accuracy of hitch position control.

Reaction:

To prevent potential malfunctions or unsafe hitch operations due to unreliable sensor readings, the hitch system has been automatically disabled.

Recommendations:

  • Check the rear hitch control lever sensor and its circuit for signs of electrical wear, damage, or degradation that could be causing the low voltage readings.
  • Use a multimeter to verify the actual voltage levels at the sensor, confirming that they are indeed below normal operating standards and pinpointing the location of voltage drops.
  • Inspect all related wiring and electrical connections for signs of wear, corrosion, or looseness that could impact voltage delivery.
  • Ensure that all power sources, such as batteries and alternators, are functioning properly and providing adequate voltage to the sensor circuit.
  • If necessary, replace the sensor or repair any faulty wiring and components identified during the inspection. After making repairs, recalibrate the hitch control system to ensure proper functionality.

Note:

Maintaining proper voltage levels in sensor circuits is critical for the accurate and safe operation of hydraulic controls like the rear hitch. Regular electrical maintenance can help detect and correct voltage issues before they lead to more significant system failures.
