System Function and Control
The 2012–2013 Nissan Versa automatic transaxle manual outlines the electronic control architecture managed by the Transmission Control Module (TCM). It details how the TCM processes critical inputs from the accelerator pedal position sensor, vehicle speed signal, and turbine speed sensor to manage shift solenoids A and B. You get a clear breakdown of line pressure control strategies. These specific routines are designed to optimize shift quality across various operating temperatures and throttle positions. Working on automotive transmission electronics involves inherent physical and electrical risks. Always ensure the vehicle is properly supported and wear protective gear before testing live circuits.
Diagnostic and Specification Data
Specifications are provided for the automatic transaxle electrical system. This section delivers precise terminal reference values for the TCM connector alongside solenoid circuit voltage ranges. It lists the exact conditions required to trigger fail-safe mode when electrical input anomalies are detected. Fast access to these factory parameters accelerates your transaxle repair diagnostics. For instance, the line pressure solenoid valve operating voltage is explicitly listed as 1.5–3.0 V during release and 0 V during wide-open throttle. Additionally, the document confirms the input speed sensor signal frequency operates at 360 Hz when driving at 20 km/h.
