System Tests: Notes
WARNING: This page is about a different car, the 2002 Chevrolet Monte Carlo, 2002 Chevrolet Impala, 2001 Chevrolet Monte Carlo, and 2001 Chevrolet Impala. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Electronic modules are sensitive to static electrical charges. Proper grounding of technician and workplace is essential to prevent damage.
CAUTION:
When using scan tool, exit all scan tool tests before cycling ignition switch from OFF to RUN position unless scan tool instructions indicate otherwise. Follow all scan tool manufacturer's instructions, or diagnostic trouble codes (actual or false) may set, vehicle systems may malfunction or scan tool may malfunction.
NOTE:
For component locations, see COMPONENT LOCATIONS
. For wiring circuit identification, see WIRING DIAGRAMS
.
NOTE:
Use adapter from Terminal Test Adapter Kit (J-35616-A) connected to DVOM when making all measurements.
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:
Do not replace Body Control Module (BCM) unless a DTC remains current after all DTC repairs have been performed. Do not replace BCM if only history DTCs are set.
NOTE:
Always check module ground and power circuits prior to replacing a control module. See DATA LINK CONNECTORS, GROUND DISTRIBUTION and/or POWER DISTRIBUTION in appropriate SYSTEM WIRING DIAGRAMS article in ELECTRICAL.
