System Testing
NOTE:
For testing procedures on anti-theft systems, see ANTI-THEFT SYSTEMS article. For testing procedures on power door lock system, see DOOR LOCKS - POWER article.
CAUTION:
When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in the GENERAL INFORMATION section before disconnecting battery.
Verify the customer complaint by operating power door locks. Visually inspect for obvious sign of mechanical and electrical damage. If no visual damage is evident, perform appropriate diagnostic test. See SYMPTOM CHART. A digital volt-ohmmeter is required to test the power door lock system.
