Spn-876 compressor clutch circuit.

A/C Clutch Relay. The air conditioning electronic control module can control a high-current component like the compressor clutch by applying a low current to the circuit's relay. Electromechanical relays use a coil that controls contacts or an arm that swings between two contacts. When the relay is open, the compressor's clutch is disengaged ...FMI 5 – Current Below Normal or Open Circuit: CRS1 open circuit for 2 seconds. FMI 6 – Current Above Normal or Shorted Circuit: CRS1 commanded on and shorted to ground. FMI 7 – Mechanical System Not Responding: The LCA Position Sensor reports the clutch is released while the clutch control system is attempting to engage the clutch.

Resistance Test: Perform an A/C clutch coil resistance test with an Ohmmeter. Typically, a clutch coil should be between 2 and 5 Ohms, and any reading below 2 Ohms or over 5 Ohms indicates a bad coil. A reading of 0.00 indicates that there is a shortage in the windings. A reading of O.L. or infinity indicates an opening in the windings. I have a 2011 Freightliner Cascadia. I have two Fault codes. I had the A/C on today and it never seemed to get cold. Any ideas on where two start. 1. check wiring to ac clutch for broken or frayed wires. check the connector for damaged pins. 2. check all your lights. make sure all your lights work. 6xvshfw 3dudphwhu 1xpehuv 631 &rghv rq - gdwd olqn 7kh 6xvshfw 3dudphwhu 1xpehu 631 lv gldjqrvwlf idxow frgh whuplqrorj\ irxqg rq vrph ri rxuStep 2: Checking for Power and Ground. To determine if the AC compressor clutch is receiving the necessary power and ground signals, follow these steps: Turn off the engine and disconnect the negative terminal of the battery for safety. Locate the clutch relay in the fuse box or relay panel and remove it.

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.
