I have a 2005 Honda Accord (CM2) with a complex electrical fault where the turn signals (both left and right), high beam headlights, and cruise control have all failed simultaneously. However, the hazard warning lights, low beam headlights, horn, and windshield wipers all continue to work normally. My diagnostic appointment is scheduled for 2026-07-20 and I need expert guidance on the following: 1. COMBINATION SWITCH DIAGNOSIS: Is the combination switch (multi-function stalk assembly, Honda part number 35255-SDA-305) the most likely single point of failure, given that all failed functions are controlled through the same stalk? What are the specific failure modes to check? 2. CONNECTOR PIN-OUT: Please confirm the 18-pin combination switch connector pin-out diagram: pin 1 = right turn signal feed, pin 5 = left turn signal feed, pin 8 = high beam, pin 12 = cruise control set/resume. Are these correct for the CM2 variant? 3. CLOCKSPRING TEST: What is the correct multimeter test procedure for checking continuity through the clockspring/cable reel (part number 77900-SDA-A22) to verify it has not failed, especially given that the airbag warning light is NOT illuminated? Which pins should show continuity and what resistance values are acceptable? 4. MICU FUSE FAILURE: Could both the Multiplex Integrated Control Unit (MICU) fuse #22 (10A) and fuse #31 (7.5A) in the under-dash fuse box fail simultaneously due to a power surge? What would cause both to blow at the same time? 5. WIRING DIAGRAM REFERENCE: I am using Honda ETM 2005 CM2, Section 14, pages 14-120 through 14-135 for reference. Can you confirm this is the correct section for diagnosing the turn signal, high beam, and cruise control circuits? Please provide a systematic diagnostic approach to identify the root cause before my appointment on 2026-07-20.
