Error Code
Error Type
Conditions for Cause
CH1x105
Fan board communication error
Main PCB has no communication with Fan PCB
CH1x106
Fan PCB IPM Fault error
Fan PCB H/W over-current is decided
CH1x107
Fan DC link low voltage error
Fan PCB detected DC link voltage is below standard value
CH1x108
Fan board communication error
Fan PCB has no communication with Main PCB
CH1x113
Liquid pipe temperature sensor error
Sensor Open/Short
CH1x114
Over-cooling inlet temperature sensor error
Sensor Open/Short
CH1x115
Over-cooling outlet temperature sensor error
Sensor Open/Short
CH1x145
External PCB communication error
Main did not receive signal from External PCB for 10 seconds
CH1x151
4-way valve switching failure
After 5 tries of 4-way valve recovery, if pressure difference is less than 400kPa or compression ratio is less
than 1.1
CH1x152
Start-up failure
Among total of 3 cranking sequence tries, when it did not satisfy start-up success decision condition
CH1x153
Engine RPM Low problem
EC_RPM is maintained below 500RPM for 2 seconds or longer (Error check from after the point of start-up
success decision)
Or if ECU raised engine low rotation problem signal (It is not checked when it is stopped)
CH1x154
Engine RPM High problem
EC_RPM is maintained at 2301 or more for 30 minutes, or ECU raised engine excessive rotation problem sig-
nal (It is not checked when it is stopped)
CH1x155
Coolant temperature high temperature problem
Coolant temperature is maintained at 100°C or more for 3 seconds, or ECU raised engine water temperature
excessive rise signal (It is not checked when it is stopped)
CH1x156
During operation, hydraulic switch problem
Check after 10 seconds from the point of start-up success decision. When EC_RPM is 700 or more, if oil hy-
draulic switch ON state is maintained for 5 seconds, or ECU raised engine hydraulic signal during operation
(Check after 15 seconds from engine start-up)
CH1x157
Engine oil replacement notice
When engine operation hours passed 5000 hours, error output with every 2 hour interval
CH1x158
Coolant pump current problem
During the pump operation, if pump current of 1.5 or more is maintained for 100 seconds, or during the pump
operation, if pump current of 0.5 or less is maintained for 10 seconds
CH1x159
Starter motor current problem
Starter current
≥
20A and EC_RPM < 70 condition is maintained for 3 seconds or longer
CH1x160
Coolant temperature low temperature problem
Decide from 10 min. after engine start, and coolant temperature of 0°C or less is maintained for 30 seconds
