John Deere 523824.05 – SSU: SID 2 Channel Current Out of Range High

The Steering System Control Unit (SSU) has detected an abnormally high electrical current in the circuit for the second channel of the Steering Input Device (SID). The SID contains the steering wheel position sensors critical for the AutoTrac™ assisted steering system. This condition indicates a potential issue with the wiring harness connected to the SID or a failure within the sensor itself, and will typically cause the AutoTrac™ system to become disabled.

1. 1

   Attempt to clear the code and restart the vehicle to see if the fault is intermittent or returns immediately

2. 2

   Visually inspect the wiring harness and connectors between the Steering Input Device (SID) on the steering column and the Steering System Control Unit (SSU) for damage, corrosion, or loose connections

3. 3

   Isolate the faulty component by accessing the SID under the steering column covers and interchanging the connectors for the two steering wheel position sensors. Observe which fault code returns to determine if the issue is in the harness or the SID

1. 1

   Repair visible wiring damage

   Repair any visible damage, corrosion, or loose connections found on the wiring harness or connectors between the SID and SSU.

2. 2

   Replace Steering Input Device (SID)

   If the diagnostic test of swapping sensor connectors results in a different code appearing (e.g., related to sensor 1, such as 1807.06), the problem is likely with the SID itself. Replace the steering wheel position sensor/SID component.

3. 3

   Test and repair wiring harness

   If the diagnostic test of swapping sensor connectors results in the same code (523824.05) returning, the issue is likely in the wiring harness leading to the SSU. Test the harness between the SID and SSU for continuity and shorts, and repair or replace as needed.

4. 4

   Recalibrate system

   After any repairs or parts replacement, perform a recalibration of the AutoTrac™ steering system.
