Spn-876 compressor clutch circuit

Hey y'all, My AC isn't working. I'm pretty sure the compressor clutch has a bad coil. Jumpering the relay socket with a paper clip, I see 14 volts at the lead going to the compressor, but the clutch doesn't engage. I also measure open circuit between the socket on the compressor and ground, so I'm pretty sure the clutch coil is open.

Linear solenoids are solenoids that use electrical energy to move an enclosed valve a certain distance linearly. The movement of this valve opens and closes the various hydraulic circuits of the solenoid. Some transmissions which use linear solenoids to help control flow to the clutches are the 09G and U660E ( Figure 1 ).Fault Code: 2377. PID (P), SID (S): S033. SPN: 647. FMI: 3/3. Lamp: Amber. REASON: Fan Control Circuit - Voltage Above Normal or Shorted to High Source. Open circuit or high voltage detected at the fan control circuit. EFFECT: The fan may stay on continuously or not run at all. Circuit Description:Using a DVOM place the positive lead at the battery positive post and back-probe the positive side of the clutch coil connector with the negative probe. The DVOM should show 1.0 volts or less. Readings higher than 1.0 volts indicate excessive resistance in the circuit. The cause for the resistance will need to be found and corrected.Hello, I'm having a issue my freightliner cascadia(###) ###-####keep throwing code than turns off the are spn 876 fml 11 and spn 4765. ... compressor clutch circuit number 876 dated valid but below normal operation range replace the compressor expansion valve and dryer charged it still has code there's another code in it to HVAC …SPN 516497 12 126 Active Advanced Emergency Braking System J1939 Advanced Emergency Braking System 2 (AEBS2) ... short to battery or open circuit SPN 1548 5 58 Inactive HVAC-Front Control Unit FCI - voltage below normal SPN 158 4 1 ...

The torque converter clutch solenoid valve is activated, with the gear in D4, by the Transmission Control Module (TCM) in response to signals sent from the vehicle speed and the Engine Control Module (ECM).

The compressor magnetic coil wiring can be defective. You can check it by testing continuity between the two ends of the coil. If the circuit is open, then the coil wiring is cut somewhere. You will need to get the magnetic coil replaced, which in most cases would be cheaper than having it repaired. The compressor clutch could be slipping.9 INSPECT MAGNETIC CLUTCH (a) Measure the resistance according to the value(s) in the table below. Standard resistance (b) When connector terminal A1 is connected to the positive (+) battery terminal, check that the following occurs: 1) the magnetic clutch's operating sound can be heard, and 2) the magnetic clutch's hub and rotor lock.My Freightliner is making a loud high pitch whining noise.

Jun 17, 2021 · 520465. This Diagnostic code is the result of two or more HVAC actuator related faults being active. The body controller prevents A/C compressor operation when this DTC is set. . NOTE: If a problem is found in two or more of the actuator circuits, repair those circuits and clear the diagnostic trouble code. The P0740 code means that your transmission control module, the computer tasked with controlling your automatic transmission, has registered a problem with the torque converter clutch circuit. In other words, your torque converter is not functioning normally, and the cause is most likely a mechanical issue of some sort.18 SPN, SID, FMI Diagnostic Trouble Code List 52 Section 4: Removal and Installation Removal Hydraulic Compact Unit 55 Installation Hydraulic Compact Unit 56 Removal ... pg. 94 Brake Caliper Circuit pg. 97 Spring-Applied/Hydraulic Release Parking Brake Circuit 98 Changing Hydraulic Brake Fluid 99 Brake Fluid Replacement RequirementUnplug it and test, with AC switch ON in the cab, one wire at the pressure switch should have 12volts.
