swoop223, thanks for you answer, but in list code (personal cat Mexico) sendme say that is the sensor bearing (encoder), so we change for a new, but the problem now is the traction star in 5 and decrease to 1, this in less that 1 min, what do you think.

GRacias

Problem: Traction Motor, Stall Timer (16)
Display:"16". All truck operations inhibited. Line contactor OPEN and steering contactor HOLD
Possible Cause: Stall current flowed more than set time (#20) in traction motor, faulty traction inverter current sensor, shorted harness wiring, faulty traction inverter DSP card, faulty logic unit.

this is set on option #20 in controller setup

you will need the troubleshooting guide from service manual to check this and figure out where the problem is.
