Inspection Procedure

WARNING: This page is about a different car, the 2004 Toyota Camry. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK CAN BUS LINE FOR SHORT TO GND (DLC3 SUB BUS LINE, CAN-L) 
    1. Disconnect all wire harness connectors (J13, J14, J15, J17) from the junction connector.
