System Functionality and Diagnostics

This factory manual details the operation and testing of the dual-zone Automatic Climate Control (ACC) system for the 2000–2001 Mercedes-Benz E320, E430, and E55. Coverage focuses on the logic governing the push-button control panel, which integrates temperature sensors, heater core duovalves, and auxiliary coolant pumps. The text outlines version coding procedures, sensor diagnostics, and the logic for the self-diagnostic memory system. Practitioners can find details on retrieving Diagnostic Trouble Codes (DTCs) and the specific circuit testing methods required for validating temperature sensor integrity.

Specification Highlights and Component Data

Documentation includes comprehensive torque specifications and fluid requirements for the A/C compressor and related cooling circuit components. Refrigerant capacities are documented alongside specific system operating pressure testing criteria. The manual provides detailed resistance charts for multiple climate sensors, including in-vehicle, evaporator, and heater core temperature sensors to assist with circuit verification. Reference only — always consult a certified technician before performing service on this equipment. This 100-page OEM factory workshop manual covers the 2000–2001 Mercedes-Benz E320, E430, and E55 automatic A/C and heater systems, providing complete diagnostic, testing, and component-level specifications for the climate control architecture.
