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 No. 2 skid control ECU (brake actuator assembly) is installed based on the identification information.
