Case IH 518564-13 - ACM – ACM: EHR lever F sensor disagreement

This code indicates that the redundant position sensors inside the Electro-Hydraulic Remote (EHR) lever #6 (Lever F) are providing conflicting or implausible voltage signals to the control module.

1. 1

   Determine if the EHR lever was recently calibrated, or if the Armrest Control Module (ACM) / EHR control unit was recently replaced without a follow-up calibration

2. 2

   Check if the tractor's ACM is running the most up-to-date software version, as outdated software can cause false sensor disagreement flags

1. 1

   Initial Calibration

   If the EHR lever was not calibrated (especially after a controller change), perform the EHR lever calibration procedure via the AFS Pro 1200 display / Vision Pro operating system.

2. 2

   Recalibration

   If the EHR lever was already calibrated previously, repeat the EHR lever calibration procedure to see if the sensors can successfully relearn their parameters.

3. 3

   Software Flash

   If the error code returns after calibration, download the correct/latest level of software to the ACM and perform the calibration procedure again.

4. 4

   Hardware Replacement

   If the fault occurs again after software updates and a successful calibration attempt, the internal sensors of the EHR lever have failed. You must remove and replace the EHR lever assembly / EHR control unit.
