DIAGNOSTIC STATUS CODES
IT TRANSISTOR CONTROL
TRACTION
STATUS CODE
Motor field current is too low during the
-49
run mode.
MEMORY RECALL
YES
SYMPTOM
Control will only operate for a second
Circuits valid
or two before shutting down.
for
Traction
POSSIBLE CAUSE
Controller
If the fault code is intermittent, verify
that the accelerator pot is adjusted
correctly.
Check for open motor field coils or
loose or intermittent field connections,
or open F1 or F2 connections.
TRACTION
STATUS CODE
Capacitor volts are low before the line
-51
contactor closes.
MEMORY RECALL
NO
SYMPTOM
Line contactor does not close when
Circuits valid
capacitor does not precharge.
for
Traction
POSSIBLE CAUSE
Controller Defective control fuse.
• Check control fuse for open circuit.
Replace fuse, if necessary.
Loose connector at P1.
• Verify connection at P1.
Verify that hydraulic pump motor
contactor tips are not welded.
