2006 Nissan Maxima 3.5 SE and 3.5 SL A34 Service Manual (P/N PFP-27500)

• Covers 2006 Nissan Maxima A34 HVAC systems, detailing automatic A/C operation, LAN-based component communication, and accelerator control.
• Official Nissan publication (Part number PFP-27500, Revision May 2006).
• 47 pages packed with wiring diagrams, component layout illustrations, self-diagnostic procedures, and HVAC performance test tables.

Diagnostic and Control System Overview

This manual dives deep into the integrated climate control architecture. It focuses heavily on the LAN communication between the unified meter, the A/C amplifier, and the various door motors. You will find detailed signal specifications for the mode, intake, and air mix door actuators, alongside fan control amplifier operations. The documentation clearly outlines the built-in self-diagnostic functions. This makes it significantly easier to isolate sensor faults and motor position errors directly through the vehicle's own interface.

Technical Specifications and System Data

Need precise refrigerant handling data? This guide provides the exact NISSAN A/C System Oil Type S requirements and the necessary procedures for maintaining correct oil levels during component replacement. Performance charts document the expected discharge temperatures and system pressures relative to ambient conditions to help verify the refrigeration cycle accurately. It also includes specific mechanical baselines, such as the required accelerator pedal travel distance (52.6–58.2 mm).

Because working with pressurized A/C systems and sensitive vehicle networks carries inherent risks, this data is provided strictly for reference and shop-level maintenance planning. Always ensure you have the proper certification and recovery equipment before opening refrigerant lines or altering vehicle control modules.
