ALL-MODE 4WD SYSTEM TF-19 [ATX14B] C E F G H I J K L M A B TF
2005 Pathfinder Table 1 Table 2 *: After 2.5 seconds have elapsed. ● 4WD shift switch, PNP switch, Neutral-4LO switch, vehicle speed sensor and throttle position sensor are WAIT DETECTION SWITCH ● The wait detection switch operates when there is “circulating” torque produced in the propeller shaft → H) or when there is a phase difference between 2-4 sleeve and clutch drum (H → L). After the release of the “circulating” torque, the wait detection switch helps provide the 4WD lock gear (clutch drum) shifts. ● The wait detection switch operates as follows. – 4WD lock gear (clutch drum) locked: ON – 4WD lock gear (clutch drum) released: OFF ● The wait detection switch senses an actual drive mode and the 4WD shift indicator lamp indicates the NEUTRAL-4LO SWITCH The neutral-4LO switch detects that transfer gear is in neutral or 4LO (or shifting from neutral to 4LO) condi- ATP SWITCH The ATP switch detects that transfer gear is under neutral condition by L-H shift fork position. 2-4WD SHIFT SOLENOID VALVE The 2-4WD shift solenoid valve operates to apply oil pressure to the wet-multiplate clutch, depending on the CLUTCH PRESSURE SOLENOID VALVE The clutch pressure solenoid valve distributes front and rear torque in AUTO mode.
