Truck Response
No Traction
Possible Causes and
Test Procedures
1. Return throttle to
neutral.
2. Ensure linkage is
allowing throttle to
return to neutral.
3. Check throttle Hall
Effect sensor is
centered.
Sensor output = 2.5
V when centered.
4. Check connector at
J2 is tight and pins
are in good condition.
5. Failed throttle
sensor.
6. Ensure continuity
through proximity
switch.
7. Improper
parameters on
software, use
handset to verify
parameters.
8. For testing
procedures refer to
Control Card
Functional Test in this
section.
Logic
The controller will not drive the motor if the throttle is more than 25% engaged at
startup. If the controller receives a throttle input greater than 25% of full speed before
the motor is started, the controller will fault and prevent traction.
