This diagnostic trouble code is generated when the control unit detects no current at the signal input to the park lock solenoid valve 2 (Y15/2). This indicates that the circuit is open.

READ MORE

This diagnostic trouble code is generated when the control unit detects that the current at the signal input to the park lock solenoid valve 2 (Y15/2) is too high or too low. This indicates that the circuit is shorted to…
