Powertrain Control Module (Pcm)

The PCM is located between driver's side front fender and power distribution center, near the battery. The PCM power and ground circuits may be checked by performing specified No Trouble Code (NTC) test. See TEST NTC-11A CHECKING PCM POWER & GROUND CIRCUITS in appropriate BASIC TESTING - 3.8L article. Since many computer-controlled and monitored components set a diagnostic trouble code if they malfunction, also perform procedures in TESTS W/CODES - 3.8L article.
