AC compressor clutch — current below expected value The BHM measures the current on this circuit when the AC compressor is commanded ON. This fault indicates the clutch circuit is open or the wiring between the BHM and the AC compressor clutch is high resistance or open. 97F, 97C, 98Z BHM B2, M 1550 6 AC compressor clutch — current above ...This video is helpful if you are trying to troubleshoot air conditioner problems, the A/C compressor clutch in particular. Start by turning the engine on. Set the AC to the maximum cold setting. Open the hood and look at the serpentine belt to locate the AC compressor. Now, look at the pulley of the air conditioner compressor.

If one is bad then the AC will not work. The body controller also controls the AC clutch. Without connecting to the truck with software, it's unlikely you will be able to diagnose it. Like i mentioned before for 4 to 5 Minutes the A/C System works correcht. Fan running, compressor engaged, Check A/C Light off.The Fuel Pressure Relief Valve (PRV) on heavy equipment and generators is usually found on the high-pressure pump or on the common rail. This pressure relief valve is responsible for regulating the fuel pressure in the fuel rail. Common rail injections systems run anywhere between 23,000 to 29,000 PSI - if fuel pressure rises above this the Fuel Pressure Relief Valve will open to allow that ...FMI 5 – Current Below Normal or Open Circuit: CRS1 open circuit for 2 seconds.

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.Good morning. This code is for the AC clutch. It s related to the charging system. Unplug the clutch and see if the alternator is going back to 14.1 at engine run. If so, the AC clutch is pulling too much and the cause. Otherwise, the fault usually occurs when the clutch is going bad.
