Electric mirrors
Both mirrors are dead. Does that really mean both mirror motors failed?
What this lesson covers
CORE TEACHING Mirror axis motors; polarity/control; fold motors; heater; memory/module control; shared supplies; LIN/local door modules. PRACTICAL DEMONSTRATIONS AND TESTS Connector pin identification from diagram; power/ground; switch input/live data; controlled motor output; bench/direct testing only where architecture permits. ADVANCED / SCAN TOOL LAYER Scan door-module inputs/outputs; scope LIN to mirror/door electronics where fitted. KEY DIAGNOSTIC QUESTIONS Are both sides missing the same shared input? Is switch command seen? Is the module outputting? Is the mirror an intelligent node? MUST-COVER CHECKPOINTS Map simple vs module-controlled architecture; prove heavy power and ground; verify switch/request; command output; measure load current; inspect signal/network where used.
What you will be able to do
