AGREEMENT
10-18
DESCRIPTION
The left motor voltage feedback circuits
are damaged (Slave Module).
The pump motor feedback is not respond-
ing when the pump is being driven (by the
Master Module).
The right motor voltage output is higher
than expected (Master Module).
The left motor voltage output is higher
than expected (Slave Module).
The right motor voltage output is lower
than expected (Master Module).
The left motor voltage output is lower than
expected (Slave Module).
The pump motor voltage output is higher
than expected (driven by the Master Mod-
ule).
The pump motor voltage output is lower
than expected (driven by the Master Mod-
ule).
The right motor has been detected stalled.
The left motor has been detected stalled.
DESCRIPTION
Tilt sensor inputs to the control system
are not the same state.

CHECK
• Check the left motor power wiring and connections.
• Check the pump motor power wiring and connec-
tions.
• Check the pump motor for proper impedance.
• Check the right motor power wiring and connec-
tions.
• Check the motor phase to phase impedance.
• Check the motor phases for proper insulation with
the chassis.
• Check the right motor power wiring and connec-
tions.
• Check the motor phase to phase impedance.
• Check the motor phases for proper insulation with
the chassis.
• Check the right motor power wiring and connec-
tions.
• Check the motor phase to phase impedance.
• Check the motor phases for proper insulation with
the chassis.
• Check the line contactor contact.
• Check the left motor power wiring and connections.
• Check the motor phase to phase impedance.
• Check the motor phases for proper insulation with
the chassis.
• Check the line contactor contact.
• Check the pump motor power wiring and connec-
tions.
• Check the pump motor for proper impedance.
• Check the pump motor connections for proper
insulation with the chassis.
• Check the pump motor power wiring and connec-
tions.
• Check the pump motor for proper impedance.
• Check the pump motor connections for proper
insulation with the chassis.
• Check the line contactor contact.
• Ensure vehicle is not stuck on something prevent-
ing movement.
• Check for jammed or obstructed right drive motor.
• Ensure vehicle is not stuck on something prevent-
ing movement.
• Check for jammed or obstructed left drive motor.
CHECK
• Check the wiring between the two controllers and
the connections : CR2(7) to CR3(7).
