Title: POWER ASSIST SYSTEMS: POWER STEERING SYSTEM: C1567; Error in Matching of ECUs; 2019 MY RAV4 RAV4 HV [11/2018 - 02/2019]

DTC

C1567

Error in Matching of ECUs

DESCRIPTION

for Gasoline Model:

  • The power steering ECU (rack and pinion power steering gear assembly) determines whether an incompatible ECM, main body ECU (multiplex network body ECU) or skid control ECU (brake actuator assembly) is installed based on the identification information.

for HV Model:

  • The power steering ECU (rack and pinion power steering gear assembly) determines whether an incompatible hybrid vehicle control ECU assembly, main body ECU (multiplex network body ECU) or skid control ECU (brake booster with master cylinder assembly) is installed based on the identification information.

DTC No.
