Instruction

No description available.

Setting conditions of the event

The fault is entered if the SV supply voltage is smaller than 16 V for longer than 1 s with the engine running and a gear engaged.

When the SV supply voltage increases above 18 V, the fault is cleared.

Test conditions of the event

No description available.

Final function check

If the defective component cannot be clearly identified, you should try to reproduce the fault:

• Reinstall the component in the vehicle.
• Test the function.

After the fault has been eliminated, the following steps have to be carried out:

• Conduct a test drive with function check.
• Read out the fault memory.
• Check the transmission for leaks.
• Perform a final visual inspection.

These steps are necessary to ensure the entire vehicle functions.
