Fault
code
Description
Cause Solution
accelerator of FL motor
controller
0242
Low voltage at slider end of
accelerator of FR motor
controller
0342
Low voltage at slider end of
accelerator of RL motor
controller
0442
Low voltage at slider end of
accelerator of RR motor
controller
0043
High voltage at slider end of
pot2 of pump motor
controller
Excessively high output
voltage at slider end of
pot2.
Measure the voltage at the slider end of pot2,
replace it if necessary.
Note: The pin #17 of the 35-pin controller
connector is for pot2 slider end input.
0143
High voltage at slider end of
pot2 of FL motor controller
0243
High voltage at slider end of
pot2 of FR motor controller
0343
High voltage at slider end of
pot2 of RL motor controller
0443
High voltage at slider end of
pot2 of RR motor controller
0044
Low voltage at slider end of
pot2 of pump motor
controller
Excessively low output
voltage at slider end of
pot2.
Measure the voltage at the slider end of pot2,
replace it if necessary.
Note: The pin #17 of the 35-pin controller
connector is for pot2 slider end input.
0144
Low voltage at slider end of
pot2 of FL motor controller
0244
Low voltage at slider end of
pot2 of FR motor controller
0344
Low voltage at slider end of
pot2 of RL motor controller
0444
Low voltage at slider end of
pot2 of RR motor controller
0045
Pot-low overcurrent of pump
motor controller
Excessively low resistance
of potentiometer.
Overcurrent at potentiometer low end, replace
it if necessary
0145
Pot-low overcurrent of FL
motor controller
0245
Pot-low overcurrent of FR
motor controller
0345
Pot-low overcurrent of RL
motor controller
0445
Pot-low overcurrent of RR
motor controller
0046
Invalid EEPROM of pump
motor controller
1. Software error;
2. Controller fault.
1. Download the correct software version;
2. Replace the controller.
