Code E142 - Transistor Controller Disable Error
Transistor controller detected a major fault.
1. Severe overvoltage (especially at main contactor close.)
a. Check for proper voltage.
2. High current at digital input.
a. Check transistor controller outputs and wiring.
b. Replace transistor controller.
3. Open circuit in traction motor field circuit.
a. Check transistor motor field wiring and field windings in motor.
b. Replace transistor controller.
4. Shorted brake coil.
Code E150 - Drive Communication Error
ETAC did not receive CAN data from transistor controller.
1. Short or open circuit in CAN wiring.
2. Electrical noise in CAN wiring due to bad connection, outside interference or low voltage.
a. Check CAN wiring.
b. Try driving using a known-good battery.
c. Try driving in a different environment.
3. Bad transistor controller.
4. Bad ETAC.
Code E151 - Drive Communication Tx Error
ETAC could not send CAN data to transistor controller.
1. Short or open circuit in CAN wiring.
2. Electrical noise in CAN wiring due to bad connection, outside interference or low voltage (especially while
lifting or driving) possibly due to overcurrent or short circuit.
a. Check CAN wiring.
b. Try driving using a known-good battery.
c. Try driving in a different environment.
3. Bad ETAC.
Code E157 - CAN-bus Off Error
