Vehicle Interface Unit: Notes
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:
Never exchange Vehicle Interface Units (VIU) or Vehicle Communication Units (VCU) from other vehicles. VIU has a 10-digit Specific Station Identification (STID) number and VCU has an 11-digit Electronic Serial Number (ESN).
