Cause
Internal scale is out of calibration.
Refrigerant is stalled in the ISV or the
ACS 661.
ACS 661 is not shipped with database in-
stalled.
Overfill safety circuit tripped. ACS 661 is
locked out because of too much refrigerant
in ISV.
150 kg (331 lb) or more refrigerant has
been recovered since last filter change.
ACS 661 is locked out because pressure in
ISV is too high, possibly because of exces-
sively high tank temperature.
Before the ACS 661 begins evacuating
the A/C system, it checks for pressure in
the system that could damage the vacu-
um pump. In this case, system pressure is
above 0.35 bar gauge.
Failed communication with relay board.
Not enough refrigerant in the ISV to perform
a system flush.
Activation code entered into the ACS 661 is
not correct.
Filter serial number entered into the
ACS 661 is not correct.
A leak in the vehicle A/C system.
System pressure is below 0.35 bar gauge.
Accumulator pressure failed to rise above
1.10 bar within the minute before an oil
drain was supposed to occur.
Display shows filter capacity remaining until
ACS 661 locks down.
Accumulator pressure transducer is not
reading pressure correctly.
Air flow sensor is not reading air flow cor-
rectly.
Solution
Press F1 to retry calibration check. If calibration con-
tinues to fail, exit current test and contact Bosch for
repair.
Verify connections are secure and valves are in cor-
rect position.
Contact Bosch for more information.
Contact Bosch for more information.
Refer to Filter Maintenance section of this manual for
instructions to change vacuum pump oil.
Allow ACS 661 to cool before performing additional
A/C service. If problem continues, contact Bosch for
more information.
Press F1. Refer to Recover section of this manual to
recover refrigerant before proceeding.
Reset the relay board by pressing F2. If problem con-
tinues, contact Bosch for more information.
Refer to Tank Fill in Maintenance section of this man-
ual.
Verify activation code is entered exactly as received.
Capitalization is required.
Verify serial number entered matches serial number
on filter. Verify filter has not been used on ACS 661
previously.
Exit current test and perform repairs on the vehicle
A/C system.
Verify high-side (red) and low-side (blue) hoses are
connected and coupler valves open. Press F1 to re-
cover; press F2 to bypass recover and proceed to
Vacuum.
Adequate pressure is required within the accumulator
to force the oil, which has been separated from the
refrigerant, out of the system. Press F1 to retry; press
F2 to exit.
Refer to Filter Maintenance section of this manual for
instructions to change vacuum pump oil.
Exit current test and contact Bosch for more informa-
tion.
