Thermoking v100 - didn't start - no faults, no errors

[avtorespect]

Hello, I'm owner of service and we have little problem with one Thermo King v100

- there is no alarm code
- no fault

but the unit do not want to start.
We checked the connections, checked the system - ***** is about 5 bar.

Where is the problem in your oppion?
After our checking, the display in the cab occured alarm code "pse" ?

Can you help me with this?

PSe indicates a high pressure sensor faulty or disconnected. Is the condenser fan faulty? Is the condenser coil blocked/dirty?

PSE High Pressure Sensor Fault

1. This alarm code indicates that the signal from the HP
sensor is outside of the readable range (<0.5 Vdc [at 0
psi] or >4.5 Vdc [at 500 psi]), and that a fault exists
with the high discharge pressure sensor.
2. Inspect for a blocked or dirty condenser coil.
3. Inspect for a faulty High Pressure transducer.
4. Check that pin C4 at connector C-1 on PCB 1 is
connected (check for a pushed pin or loose pin crimp),
not corroded, and is not obstructed by dirt.
5. Observe the continuity between CHT (pin C2,
connector C-1) and the ground bolts.
6. Make sure that the voltage between pins C3 and C4 on
connector C-1 corresponds to the table below.
7. Check for +5 volts at pin C5, connector C-1 on PCB 1.
8. If the problem persists, replace the terminals in the
connectors of the ECM and the transducer.
9. Outside the main harness, connect the transducer
directly to the ECM.
