DIAGNOSTIC STATUS CODES

SX TRANSISTOR CONTROL

-41

Open thermal protector (TP) or

transistor over temperature.

MEMORY RECALL

CORRECTIVE ACTIONS

YES

 

Circuits valid

SYMPTOM

for

Reduced or no power to traction motor in control

range.

Traction

POSSIBLE CAUSE

Controller

Control is in thermal cut-back.

 

Allow control to cool, status code should

 

disappear.

Defective control.

Replace controller unit.
