Cat Lift Trucks (& Caterpillar) ET4000:
Cat ET4000AC error code APP-A

Hi, i need help on this one. After replacing the left drive card and the main power card, the lift won't move, but the code APP-A appeared on the display. The last A is flashing. Anyone's knows what I have to do to make the lift work?
