Danny,

This code is for a failed motor encoder or wiring. Go to the drive motor and find the encoder connector, should have 4 wires. Disconnect the connector and check voltage between pin 1 and battery negative with key on, should read 5 volts. If good, move ground test lead to pin 4 of the same connector, again should read 5 volts. I would check your battery voltage to make sure jack is fully charged. Make sure all fuses are good. Should all this check good, need to verify wires from encoder to controller are good. May have failed encoder. Swap with same model truck to verify. Good Luck.
