Скачать или смотреть Mercedes-Benz Dual Battery Systems | Diagnostic Training with Patrick Lonigro

Mercedes dual battery systems vary widely by chassis — and misdiagnosis is common. In this February training webinar, Patrick Lonigro breaks down how Mercedes 12V dual battery systems evolved, how control modules manage charging and consumer shutoff, and what commonly fails in the field.

This session covers:
• Starter vs. systems battery functions
• Additional battery (G1/7) & ECO battery (G1/13) logic
• Battery Control Modules (N82 / N82/1)
• Coupling relays, diodes, and emergency modes
• Water intrusion failures (under-seat, trunk, sunroof drains)• Dip limiter (R62) operation and failure symptoms
• Transition to park pawl capacitors on newer models
• 48V battery systems, DC/DC converters, and ISA operation
• Cooling system bleeding on M264 & M256 engines
• Common 48V battery faults and precautions

Chassis covered include 164, 166, 204, 207, 211, 212, 221, 230, 167, 205, 213, 222 and more.
