System Tests: Notes

CAUTION: When battery is disconnected or modules are replaced, 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 GENERAL INFORMATION before disconnecting battery.

NOTE: Before replacing any control module, ensure all module ground and power circuits are functioning normally. For circuit identification, see GROUND DISTRIBUTION and POWER DISTRIBUTION articles in WIRING DIAGRAMS.

NOTE: Before beginning system testing, perform PRELIMINARY INSPECTION under TROUBLE SHOOTING.

NOTE: For aid in identifying circuits or wiring during system testing. See wiring diagrams in appropriate article for system being tested.

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.
