Error code Messages When it occurs Possible solutions Action
A003 ADC NOT WORK -
ING
– Electronics fault – ADC analog-digital converter dam -
aged
– Replace the logic electronic board
A032 CIRCUIT STILL UN -
DER PRESSURE
– During the vacuum, cylinder filling
or leak test phase in vacuum
– The vehicle A/C system is pressu -
rized
– Recover the refrigerant gas from
the vehicle before starting another
vacuum phase.
A033 CIRCUIT LEAKAGE – During the vacuum, cylinder filling
or leak test phase, both under pres -
sure and in vacuum
– Leakage in the circuit
– Leakage in vehicle fittings
– Identify the leak position in the ve -
hicle or connected system and
have it repaired by trained and
qualified staff according to local
legislation.
A034 VACUUM LEVEL
TOO LOW – During tracer injection and oil injec -
tion phase. The necessary vacuum
level has not been reached.
– Vehicle A/C system is pressurised
notwithstanding the vacuum phase
– Possible presence of leakages in -
side A/C system
– Vacuum phase time not sufficient
or phase not executed (manual cy -
cle).
– Repeat cycle, increase vacuum
time
– If leakages has been identified,
identify the leak position in the ve -
hicle or connected system and
have it repaired by trained and
qualified staff according to local
legislation.
A035 CYLINDER EMPTY – During the gas injection and flush -
ing phase
– Refrigerant gas is too low for the
procedure to be completed
– Refrigerant load cell out of calibra -
tion
– Fill the internal tank
– Check calibration and calibrate if
necessary
A036 CYLINDER REFRIG -
ERANT QUANTITY
TOO LOW
– During the gas injection and flush -
ing phase
– Gas amount in internal tank less
than required
– Refrigerant load cell out of calibra -
tion
– Fill the internal tank
– Check calibration and calibrate if
necessary
A037 FURTHER REFRIG -
ERANT INJECTION
NOT POSSIBLE
– During gas injection phase – Hoses not connected to vehicle
A/C system
– Couplers closed
– Vacuum not sufficient
– Presence of pressure in the circuit
– Caution: before proceeding, empty
out the hoses
– Repeat the recovery procedure and
increase the vacuum phase dura -
tion
A038 CIRCUIT LEAK -
AGE OR DISCON -
NECTED
– During flushing phase – Leakages or obstructions in the cir -
cuit to be flushed
– Check the connection to the A/C
system
– Identify the leak in the circuit and
have it repaired by trained and
qualified staff according to local
legislation.
A043 CYLINDER FULL – During the gas recovery and hoses
emptying phase
– Internal tank full (maximum capac -
ity level reached)
– Decrease quantity of gas by filling
(injecting) an external suitable tank
(with safety valve)
A047 LP LEAKAGE – At the end of the gas injection or,
– In the Eco-Lock Lock patented
technology quick couplers discon -
nection phase, or
– During the vehicle fittings leak test
– Vehicle A/C system may have leaks
at the LP port
– Empty the vehicle (follow the pro -
cedure guided by the displayed
messages)
– Replace LP port/schrader valve in -
side LP port
A048 HP LEAKAGE – At the end of the gas injection or,
– In the Eco-Lock Lock patented
technology quick couplers discon -
nection phase, or
– During the vehicle fittings leak test
– Vehicle A/C system may have leaks
at the HP port
– Empty the vehicle (follow the pro -
cedure guided by the displayed
messages)
– Replace HP port/valve inside HP
port
A049 LP AND/OR HP
LEAKAGE – At the end of the gas injection or,
– In the Eco-Lock Lock patented
technology quick couplers discon -
nection phase, or
– During the vehicle fittings leak test
– Vehicle A/C system may have leaks
at the HP and/or LP ports
– Empty the vehicle (follow the pro -
cedure guided by the displayed
messages)
– Replace HP and/or LP ports/valves
inside ports
