Pioneer 6 disc PD-M601

I need to know how to put into test mode. It does not have a button
on the main board called test, just a 6 pin TP1. Do I need a special
cable? It moves the slider to home, but the spindle never spins all
the time and jumps to the next CD. Laser lights and moves in and out.
It does not show a voltage on the spindle motor.
Thanks
