CLAAS A015h: Fault in 1 valve not returning to neutral

The 1 valve does not return to neutral within the specified time. This issue may be related to oil viscosity caused by low temperature, which affects the valve's performance. If the problem persists after warming up the tractor, the 1 valve may need to be replaced.

   Oil viscosity and temperature

2. 2

   Operation of the 1 valve after warming up the tractor

3. 3

   Presence of the fault code after warming up

1. 1

   Check oil viscosity and temperature

   Ensure the oil is at the correct viscosity for the current temperature. Low viscosity due to low temperature may affect the 1 valve's performance.

2. 2

   Warm up the tractor

   Allow the tractor to warm up to normal operating temperature and retest the operation of the 1 valve.

3. 3

   Verify fault code

   If the error reappears after warming up, the 1 valve may need to be replaced.
