Fault
code
Description
Cause Check
0341
High voltage at slider end
of accelerator of RL motor
controller
0441
High voltage at slider end
of accelerator of RR motor
controller
0042
Low voltage at slide end of
accelerator of pump motor
controller
Excessively low output
voltage at slider end of
accelerator.
Measure the output voltage at the slider end
of accelerator to check if it is too low, replace
the accelerator if necessary.
Note：The pins #16 of the 35–pin controller
connector is for accelerator slider end input.
0142
Low voltage at slider end of
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 if necessary.
Note：The pins #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

voltage at slider end of
pot2.
Measure the voltage at the slider end of pot2,
replace if necessary.
Note：The pins #17 of the 35–pin controller
connector is for pot2 slider end input.
