INSPECTION PROCEDURE

NOTICE:
Inspect the fuses for circuits related to this system before performing the following inspection procedure.
HINT:
Check the condition of each related circuit connector before troubleshooting (RAV4_ACA30 RM000000UZ306OX.html).
1.CHECK WIRE HARNESS (4WD CONTROL ECU BSLC TERMINAL)

  1. Disconnect the E67 ECU connector.
