Toyota RAV4 Service Manual: Open in one side of can branch line

Toyota RAV4 Service Manual / Can communication / Fail-safe chart / Open in one side of can branch line

Description

If 2 or more ecus and/or sensors do not appear on the intelligent tester's "bus check" screen via the can vim, one side of the can branch wire may be open. (One side of the canh [branch wire] /canl [branch wire] of the ecu and/or sensor is open.)

Inspection procedure

Notice:

Hint:

  1. Check for open in one side of branch wire (abs and traction actuator)

  1. Disconnect the a19 abs and traction actuator (skid control ecu) connector.
  2. Select "bus check" on the intelligent tester display via the can vim (see page ca-34).

Result




  1. Check for open in one side of branch wire (abs and traction actuator branch wire)
