Pin Voltage Tests

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 GENERAL INFORMATION before disconnecting battery.
CAUTION: Before disconnecting battery, obtain anti-theft code for radio. After battery is reconnected, the word CODE will appear on radio display. Enter 5-digit anti-theft code using select buttons and radio will begin working. If code is entered wrong 10 times, leave radio on at least one hour and enter code correctly. Any time radio power is lost, pre-selected radio stations will have to be set. For more information, see owners manual.
NOTE: Unless stated otherwise in testing procedures, preform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance. Carefully backprobe PCM harness connector using Backprobe Set (07SAZ-001000A) to avoid connector damage. Voltage readings may vary slightly due to battery condition or charging rate.
NOTE: PCM may also be referred to as ECM. Generator may also be referred to as alternator.

Pin voltage charts are supplied to reduce diagnostic time. Checking pin voltage at the PCM connector determines whether PCM is receiving and transmitting proper voltage signals. Diagnostic charts may also help determine if PCM harness is shorted or open. See Fig 1-Fig 37 .
