There are no approved repairs to Supplemental Restraint System (SRS) or High Voltage (HV) wiring or connectors. SRS system wiring and connectors
are color coded yellow and HV wiring is orange however vehicle-specific wiring diagrams are the best source for identifying wiring in these circuits.
Wiring diagrams are available through the Technical Information System (TIS) www.techinfo.toyota.com.
If SRS or HV wiring or connectors are suspected of damage they should be inspected thoroughly. Damaged wiring and/or connectors require
replacement of the affected harness. Follow all precautions and procedures outlined in model-specific repair manuals for replacing SRS wiring or
components. Only Certified Hybrid Service Technicians are qualified to replace HV system wiring and components.
