21
Throttle Fault
0x2210
• Throttle wiring fault
• Incorrect throttle type setting
• Incorrect throttle operation
• Steering angle pot wiring fault
1 The throttle AD data is out
of range for 48ms.
Cycle the keyswitch. Shut down throttle
2 The HPD Sequencing fault
is active for 10s.
3 The steering angle AD data
isout ofrange for 48ms.
4 The throttle calibration
process failed.
22
HPD
Sequencing
0x2211
• Incorrect throttle operation
• Defective throttle
1 At least 10% throttle
is applied for 48ms
before the interlock state
changes to on.
Release the throttle before
10s expires. If the HPD
Sequencing fault is active
for more than 10s, the
Throttle Fault is generated.
Shut down throttle
23
Main Relay
Welded
0x2220
Defective main relay 1 The Capacitor Voltage is
greater than (Keyswitch
Voltage − 0.7V), and the
capacitor bank voltage
drop is less than 1.5V
after the Main Welded
PWM is applied to the
motor for 96ms.
Cycle the keyswitch. Shut down motor
Shut down main
contactor
Shut down throttle
Shut down interlock
24
Main Relay
Did Not Close
0x2221
• Defective main relay
• Incorrect Pull In Voltage
1 The difference between
the keyswitch voltage
and capacitor voltage
is greater than the DNC
Voltage Threshold for
96ms when the relay is
engaged.
Cycle the keyswitch. Shut down motor
Shut down main
contactor
Shut down throttle
Shut down interlock
2 The difference between
the keyswitch voltage
and capacitor voltage
is greater than the DNC
Voltage Threshold for
96ms after the relay ison.
25
Main Driver
Fault
0x2222
Defective main relay driver 1 Main relay feedback is
high when the relay is on
for 100ms.
Cycle the keyswitch. Shut down motor
Shut down main
contactor
Shut down throttle
Shut down interlock
2 Main relay feedback is
low when the relay is off
for 100ms.
26
Precharge
Failed
0x2223
The PTC resistor in the precharge
circuit is defective.
1 The Capacitor Voltage
is less than 65% of the
Keyswitch Voltage for
500ms after the Keyswitch
Voltage is greater than
60% of the nominal
voltage at startup.
Cycle the keyswitch. Shut down motor
Shut down main
contactor
Shut down throttle
Shut down interlock
2 The Capacitor Voltage
is less than (Keyswitch
Voltage − 4V) before the
relay is engaged.
