Case IH 4216-18 - DEC – EHR (Electronic Hitch/Remote) / Transmission Control Unit (TCU): Transmission reverse clutch solenoid minimum quick fill calibration time limit exceeded

The exact fault code 4216-18 could not be verified in public Case IH literature. Depending on the specific machine and module, code 4216 translates to 'Rear Remote No.1 - Valve Spool Not Calibrated' (EHR Module) or 'Short circuit to ground at clutch K3' (TCU).

• Case IH Magnum 235–340 (Series 4)
• Case STX Steiger tractors (350 to 600 HP)
• Case C, D, & E Series Wheel Loaders

1. 1

   If diagnosing the Transmission Control Valve (ZF/Case TCU 4216): Check the cable running from the Transmission Control Unit (TCU) to the transmission control valve for damage or shorts to ground

2. 2

   If diagnosing the Transmission Control Valve (ZF/Case TCU 4216): Inspect the connectors from the TCU to the transmission control valve for corrosion or backed-out pins

3. 3

   If diagnosing the Transmission Control Valve (ZF/Case TCU 4216): Measure the regulator resistance on the clutch solenoid

4. 4

   If diagnosing the Transmission Control Valve (ZF/Case TCU 4216): Check the internal wire harness of the transmission for continuity and shorts

5. 5

   If diagnosing the Rear Remote Valve (Case IH EHR 4216): Verify that the rear remote valve spool has been properly calibrated using the tractor's display or diagnostic tool

1. 1

   Repair or replace wiring harness

   For the Transmission Solenoid Short (Clutch K3 / Reverse Solenoid): If the diagnostic checks reveal a short to ground in the wiring harness, repair or replace the affected harness section.

2. 2

   Replace clutch/reverse solenoid

   For the Transmission Solenoid Short (Clutch K3 / Reverse Solenoid): If the resistance check on the solenoid fails, drain the transmission fluid, access the transmission control valve body, and replace the faulty clutch/reverse solenoid.

3. 3

   Calibrate Rear Remote No. 1

   For the EHR Valve Spool: Enter the tractor's calibration menu and execute the calibration procedure for Rear Remote No. 1.

4. 4

   Replace spool valve or position sensor

   For the EHR Valve Spool: If calibration fails repeatedly, the spool valve or its position sensor may require replacement.
