COMPRESSOR CODE 34
Separator Tank Pressure Greater Than 20 psi at Crank
Troubleshooting Steps
Action Result
Step 1:
Wait until separator tank pressure is below 20 psi
and try to crank the machine.
Step 2:
With air system completely blown down, check
WEDGE diagnostic display 5 to verify pressure value
is 0 psi.
Step 3:
Check all harness connections between WEDGE
and PT1 pressure sensor.
Repair harness as needed
Step 4:
Disconnect PT1 from harness and plug pressure
transducer simulator (Part No. 22168868) into the
harness connector. Check WEDGE diagnostic
display 5 to verify pressure value is between 186 psi
and 196 psi.
If pressure value on display 5
is not between 186 psi and
196 psi, check for WJDing
problems
If pressure value on display 5
is between 186 psi and 196
psi, replace PT1 pressure
sensor
Step 5:
If Steps 3 and 4 checkout OK, replace WEDGE.
Explanation:
The WEDGE has detected a pressure from PT1 pressure sensor that is greater than
20 psi at the time of engine crank.
Effect:
Code 34 is a SHUTDOWN condition and will prevent cranking until the separator
tank pressure is below 20 psi. The Compressor Malfunction light will be on solid, and
Code 34 will be displayed.
