Diagnostic and Electrical Scope

The 1996 Nissan Pathfinder R50 service publication details the operation of the RE4R01A transmission, providing extensive technical data for control unit functions and signal diagnostics. It maps the interaction between sensors—such as the vehicle speed, throttle position, and fluid temperature sensors—and the A/T control unit. Documentation includes detailed flow charts for troubleshooting shifting malfunctions, torque converter lock-up issues, and engine brake performance. The text also covers the pinout specifications for the control unit harness, ensuring precise identification of circuits for line pressure solenoids, shift solenoids, and the overdrive control switch.

Specification and Reference Values

Technical data provided includes critical voltage thresholds and fluid parameters essential for assessing transmission health. Fluid temperature sensor output is documented at 1.5V when cold (20°C/68°F) and 0.5V when hot (80°C/176°F). The line pressure solenoid valve duty is specified at approximately 0% for low-pressure/small-throttle conditions, scaling to 95% for high-pressure/large-throttle operations. Further reference values are listed for the throttle position sensor, which registers 0.5V at fully-closed and 4V at fully-open throttle. Valve clearance for the intake is listed at 0.11–0.20 mm in the cylinder head specification table. Coolant system capacity for the 1996 Nissan Pathfinder R50 is documented at 2.73 liters. The magneto pick-up coil resistance is specified at 450–650 ohms. For additional technical insights, how factory workshop documentation is structured provides further clarity on using these reference charts for accurate component diagnosis.
