Powertrain Control Module: Notes
CAUTION:
Powertrain Control Module (PCM) is electrostatically sensitive. Before servicing PCM, technician must ground himself and work area to avoid possible build-up of electrostatic charge and damage to PCM. Do not remove part from packaging until ready to install. Ground any static-proof package before opening. Do not touch electrical terminals of components unless properly grounded. Do not lay electrical components on car seat, carpeting or dashboard. Use electrostatic protection mat and ground strap whenever possible.
CAUTION:
Use correct fastener in correct location. Replacement fasteners must be correct part number for application. Fasteners requiring replacement or fasteners requiring use of thread locking compound or sealant are identified in service procedures. DO NOT use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage fastener. Use correct tightening sequence and specifications when installing fasteners in order to avoid damage to part and systems.
NOTE:
Before replacing Powertrain Control Module (PCM), carefully inspect all wiring and control components. Failure to test for short circuits may result in repeated PCM failure due to shorts. To prevent internal damage to PCM, ensure ignition switch is in OFF position when connecting or disconnecting PCM harness connectors or any electrical components.
