Atc Fault Code 134 - New Holland T8010 Manual

High pressure switch cycling error (2 times in 1 minute)
Cause:
Incorrect charge in system
Wire harness/connector failure
NOTE: If system is properly charged, then the high pressure switch will be closed and the failure could be on either
leg of the switch.
High pressure switch failure
ATC module failure
Possible failure modes:
Compressor clutch locked out until unit is cycled off then back on.
Solution:
1) Verify that system charge is within specification.
2) Inspect harness and connectors for possible shorting between high pressure switch wires (both leads) and other
wires or possible open condition. If a short or open exists then replace harness.
3) Disconnect high pressure switch from harness and check its resistance. It should be closed (measure around 0
Ohms) if system charged correctly. Replace if faulty.
4) If no fault found with system charge, wire harness, connectors, or high pressure switch then replace ATC
module.
Cause:
Wire harness/connector failure
NOTE: If system is properly charged, then the low pressure switch will be closed and the short could be on either
leg of the switch.
ATC module failure
Possible failure modes:
Compressor clutch disabled.
Solution:
1) Inspect harness and connectors for possible shorting between low pressure switch wires (both leads) and other
wires. If a short exists then replace harness.
2) If no fault found with wire harness, or connectors, then replace ATC module.
