Symptom Testing: Notes

NOTE: To determine appropriate test, see SYMPTOM CHART TABLE. Unless otherwise directed, perform tests in order listed.

Verify the customer complaint by operating power seat. Visually inspect for obvious sign of mechanical and electrical damage. If no visual damage is evident, go to SYMPTOM CHART TABLE. A digital volt-ohmmeter is required to test the power seat system. See WIRING DIAGRAMS for pin numbers. These connectors are identified in illustration. See Figure -9.
