Compressor types that can be tested are:
Denso: 5SER09, 5SE09C, 6SEU14, 6SEU16, 7SEU16 and 7SEU17
Sanden: PXE13 and PXE 16
The clutchless technique demands new ways of analysing the root cause and conduct the
correct diagnosis as it is harder to measure the signals to the electronically controlled valve.
However, it is crucial to know if the valve is reacting properly to steering signals or not before
opening the AC-loop.
- Is the malfunction dependant on the
electronics or the AC-Loop?
- Costs not chargeable to the customer
- It does NOT require any dismounting,
simply disconnect the compressor cable and
connect the tester.
- It gives you an answer within 15 minutes
- Invite your customer for a coffee meanwhile
you diagnose the problem.
- The CLT enables you to a better perceived service level
What does it cost to open the loop
- Cables for BMW, MB, Toyota and VAG applications
- Compressor simulator to prevent faults to be saved in the on board computer during
the repair
- Power supply cable – tester connected to the vehicle battery

I have been using the CLT1 to verify operation of these clutchless compressors , mostly fitted to newer VAG cars. Its quick and easy to connect the CLT1 direct to the compressor connector and to the car battery for power. You also get a dummy load to put onto the loom wiring to prevent fault codes from the climate unit.
You can check the solenoid operation on the compressor for open circuit or short circuits and furthermore you can take over control of the solenoid to exercise the compressor independently.
Most of the time I plug it into a ‘dead’ compressor and I can hear the solenoid clicking on/off as I increase/decrease the levels on the CLT1 whilst watching for pressure level changes on my gauges. On a dead compressor the pressure for suction and discharge stay the same i.e. no change or difference indicates a dead solenoid control inside the compressor. This gaurantees you have a dead compressor and replacement can then take place confidently.
The majority of compressors fail without any internal damage so a straight swop for a new unit is possible without the need for a system flush. However some compressors will be dead on the solenoid as well as causing the rest of the AC system to be contaminated. In this case you have no option except to flush and replace other components to clean out the system.
Note that the climate control system will not display a fault code with a failed solenoid unless the solenoid is short/open circuit. In my experience this never happens and so the climate control unit cannot diagnose an internal fault to the compressor and assumes all is well.
Using the CLT1 proves you have a dead compressor and speeds up the diagnosis. Using the tool it takes less than 5 minutes to hook it up , push the buttons and come to the right diagnosis.
