P2771: Transmission Fluid Cooler Control Circuit Low – Explained
The P2771 code is related to the four-wheel drive low switch circuit in vehicles equipped with an active transfer case. It consists of the PCM, transfer case control module, and circuit wiring.
The transfer case control module controls the 4WD low signal on the low signal circuit. When the operator selects 4WD low, the transfer case control module grounds the signal circuit, and the 4WD low signal voltage on the circuit changes from ignition voltage to zero volts. The PCM then compensates for transfer case gear reduction in the transmission output shaft speed (OSS) sensor signal.
