Symptom Tests: Notes
CAUTION:
Static electricity can destroy integrated circuits in Instrument Panel Cluster (IPC) and Vehicle Speed Sensor (VSS) calibrator. Before servicing these components, ground yourself and work area to discharge static electricity.
NOTE:
Unless otherwise specified, make all voltage and resistance measurements with a Digital Volt-Ohmmeter (DVOM) having an input impedance of 10 megohms or greater.
NOTE:
For component locations, see COMPONENT LOCATIONS . For wiring and circuit identification, see WIRING DIAGRAMS .
If sent to SYMPTOM TESTS from INSTRUMENT PANEL CLUSTER (IPC) DIAGNOSTIC SYSTEM CHECK perform appropriate test. See SYMPTOM INDEX table.
