System Overview and Diagnostics

This service publication provides a comprehensive set of diagnostic data and component descriptions for the audio and accelerator systems. It details hardware such as the audio unit, door speakers, front tweeters, and satellite radio tuner while providing precise signal descriptions for both base and Bose configurations. Wiring schematics cover both Coupe and Sedan variants, documenting communication signal circuits, steering switch resistance values, and power supply pathways. Having these exact specifications directly improves shop efficiency by eliminating guesswork during complex electrical diagnostics. Understanding the factory structure is critical when tracking down intermittent audio symptoms.

Component and Electrical Data

The accelerator control section outlines assembly components and crucial physical parameters. Note that the accelerator pedal assembly contains sensitive electronic sensors and must never be disassembled during service work to prevent irreversible damage or vehicle malfunction. Total accelerator pedal travel is officially specified at 48.5–53.5 mm (1.91–2.11 in). For technicians testing steering wheel controls, the switch resistance for volume functions is documented at 487 ohms. Communication signal diagnostics include oscilloscope reference values for the satellite radio tuner and audio unit RX/TX lines, giving you the exact baselines needed to verify module integrity. Harness continuity charts list exact terminal mappings for front and rear speaker signal paths. At 100 pages, this official OEM publication acts as the authoritative desk reference for completing an accurate system repair on this specific platform.
