Inspection Procedure

WARNING: This page is about a different car, the 2002 Toyota Prius. However, it is still accessible from the selected car via links, so may be relevant.
  1. Check for open, short and +B short in wire harness between HV ECU ABFS terminals and AIRBAG ECU GSW 2 terminal  . See HOW TO USE THE DIAGNOSTIC CHART AND INSPECTION .
    NOTE: Confirm that there is no open circuit in the wire harness. If the battery voltage is always applied to the HV ECU ABFS terminal with the ignition ON, the AIRBAG signal circuit has +B short.
