Spn-876 compressor clutch circuit.

After inspecting the belt, there can only be two things left that could be happening: 1. The clutch is not getting a signal to turn on. This indicates some form of wiring problem. -or-. 2. The AC compressor is getting a command to turn on but is no longer able to, which would indicate that it needs replacing. 2.One of the reasons why compressors do not engage is because of a low pressure lockout, a poor ground, a bad clutch coil, an opening in the wire to the clutch coil, or simply a blown fuse. There are several ways A/C compressor clutches receive power. One, the relay can be operated by the PCM (the PCM interprets the condition of the low and high ...Resistance Test. You can also do an A/C clutch coil resistance test using an Ohmmeter. The clutch coil should have a range between 2 to 5 Ohms. If you get a reading lower than 2 Ohms or beyond the 5 Ohms, this is indicative of a bad coil. If your reading is 0.00, then, most probably, there is a short circuit in the windings.A/C Clutch - protection mode (voltage too low) SPN 876 1 7 Inactive Modular Switch Field Voltage below normal, or shorted to ground SPN 168 4 2 Inactive SAM Chassis Electrical Potential (Voltage) - Voltage Below Normal Or Shorted To Low Source SPN 168 4 3 Inactive SAM Chassis Tail Lamp Left - Current Below Normal Or Open Circuit SPN 520918 5 1I have issues with this code SPN 876 fmi 5.

There are two other "right out of the box" clutch issues that are encountered with some regularity on tech line calls. These are: 1. No clutch function at all. (Usually due to an "open" clutch coil.) 2. The A/C compressor clutch circuit blowing fuses. (Usually due to clutch coil resistance being too low.) As a result, it is advisable to ...

Now, start your car, turn on the AC, and observe the gauge readings. For most systems, a normal low-side reading will fall between 25 and 40 psi, while the high-side will range from 200 to 350 psi. If the readings are significantly higher, it may indicate an overcharge. If you do get an engage and the power probe does not kick out, then one of the plugs on the circuit had a pin vibrate loose. Most times you will find the clutch is burned up. Here is the manufactirer info below for the fault. A/C Compress or clutch - Current below normal, or open circuitPrint. ECM: Freightliner - SAM Cab. Fault: SPN 522006 FMI ... The most common reason why your AC clutch is not engaging is that the AC refrigerant level is too low or too high.
