Spn-876 compressor clutch circuit.
There are a number of things that could be the cause of the clutch turning off; the front air control, the BCM, the ECM or the IPDM. Since you wired up the clutch directly we know the clutch is OK. High temp and/or pressure (over 398 PSI) will turn off the clutch, as well as throttle position.
The purpose of the A/C clutch relay control circuit is to control the operation of the air conditioning. This is accomplished by providing power to the A/C clutch to engage the A/C compressor. Based on the specific vehicle, this circuit can be very complex and include several control modules. Code P0646 is set by the PCM when it detects a low ...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.Toyota Tacoma (2015-2018) Service Manual / Air Conditioning / Air Conditioning System(for Automatic Air Conditioning System) / Compressor Lock Sensor Circuit (B1422/22) SYSTEM DESCRIPTION The ECM …
In the "on" or "engaged" position, an A/C compressor's clutch transmits 100 percent of the rotation force applied by an engine's serpentine belt, directly to the compressor's driveshaft. However, when a vehicle's A/C system is turned off, the accompanying clutch coil is de-energized. In turn, the A/C system clutch disengages.520349 FMI 14. 520349: TxId: 61 SPN: 520349 FMI: 14 - 520349: TxId: ...
