Replace lift potentiometer.
Bad potentiometer.
Inspect and repair wiring as necessary.
Wiring to lift potentiometer broken or shorted.
PERFORM INPUT TEST 04 - LIFT/LOWER POTENTIOMETER VOLTAGE. Look for “dead spots”,
sudden voltage jumps, etc.
Solution
Possible Cause
Lift potentiometer voltage is outside the normal
operating range (0.39V to 4.63V). Note: actual
voltage supplied to potentiometer is 15V.
LIFT system shutdown.
Criteria
Resulting Effect
LIFT/LOWER POTENTIOMETER VOLTAGE OUT OF RANGE
Fault condition

Replace steer position potentiometer.
Bad potentiometer.
Inspect and repair wiring as necessary.
Wiring to steer potentiometer broken or shorted.
Adjust steer position potentiometer or replace if
necessary.
Steer position potentiometer out of adjustment.
PERFORM INPUT TEST 05 - STEER POSITION POTENTIOMETER VOLTAGE. Look for “dead
spots”, sudden voltage jumps, etc.
Solution
Possible Cause
Steer position potentiometer voltage is outside the
normal operating range (0.29 V to 4.7 V). Note:
actual voltage supplied to potentiometer is 15V.
TRACTION system shutdown.
Criteria
Resulting Effect
STEER POSITION POTENTIOMETER VOLTAGE OUT OF RANGE
Fault condition

Warning: Tampering with traction amplifier may void warranty.
Swap amplifier harness connections at J2 and J6 on
the controller. If the error code changes sides, then
the controller is good. If the code does not change
sides, the controller is bad. Now swap the harness
connections at the amplifiers. If the code changes
back to the original side, then the amplifier is bad.
If the code does not change back, the harness is
bad.
Bad amplifier harness or amplifier.
Solution
Possible Cause
Left/right traction amplifier temperature sensor
voltage is outside the normal operating range.
TRACTION shutdown.
