code
Description
Cause Solution
3. Controller damaged.
module works properly;
3. If the inspections above fail to discover the
problem, replace the motor.

Open-circuited FR motor
controller

0437
Open-circuited RR motor
controller
0038
Fused main contactor of
pump motor controller
1. Fused contact of main
contactor;
2. Improper wiring.
1. Check the main contactor for fused
contact;
2. Measure the coil voltage for abnormality;
3. Check for correct wiring;
4. If the motor has missed phase, check the
UV phase for unlinked cable.

Main contactor engaging
failure of pump motor
controller
1. Large voltage drop in
KSI voltage and battery
voltage;
2. An element with high
power is connected in
series in the KSI circuit,
which brings the volt-
age drop;
3. Contactor damaged.
1. Use a handhold to monitor the KSI, ensure
the difference between the capacitor volt-
age (monitor/outputs menu capacitor Volt-
age) and the key switch voltage
(Keyswitch Voltage) is less than the
threshold (programme/main contactor/
main DNC threshold).
2. Check whether an element with high
power is connected in the KSI circuit,
which brings the voltage drop;
3. Replace the contactor to find out if it is
damaged.

High voltage at slider end of
accelerator of pump motor
controller
1. Accelerator wiring
disconnected;
2. Excessively high out-
put voltage at slider
end of accelerator.
Measure the output voltage at the slider end
of accelerator to check if it is too high, replace
the accelerator if necessary.
Note: The pin #16 of the 35-pin controller
connector is for accelerator slider end input.

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 pin #16 of the 35-pin controller
connector is for accelerator slider end input.
