Case IH 517959-03 - DEC – DEC: Transmission A2 clutch solenoid electrical circuit fault voltage above normal

The controller has detected that the voltage in the A2 clutch solenoid circuit is higher than the expected normal range, typically indicating a short circuit to a power source, an open circuit, or a failed solenoid coil.

1. 1

   Note: The A2 clutch solenoid is the first of 11 transmission components calibrated; a fault here will halt or prevent successful transmission calibration.

2. 2

   Inspect the wiring harness between the DEC and the A2 clutch solenoid for a short circuit to a power source

3. 3

   Check the circuit for an open circuit condition

4. 4

   Inspect connections for poor or corroded contacts

5. 5

   Check the A2 clutch solenoid coil for internal failure

1. 1

   Repair wiring

   Repair any shorted or open wiring in the A2 clutch solenoid circuit.

2. 2

   Replace solenoid

   Replace the A2 clutch solenoid if the coil is internally failed.

3. 3

   Calibrate transmission

   Rerun the automated transmission calibration sequence via the multi-function handle/display to ensure the A2 clutch solenoid (and the subsequent 10 components) calibrate successfully.
