Description This dtc is output when: 1) during key code registration, a key malfunction occurs; 2) the key code was unable to be registered properly. Inspection procedure Reregister key Clear the dtc (see page ei-18). Reregister the key code with the transponder key ecu (s ...

Fail-safe chart
Fail safe operation If there is a problem with any sensor signals or actuator systems, the skid control ecu prohibits the power supply to the abs and traction actuator and informs the ecm of vsc system failure. The abs and traction actuator turns off the solenoids and the ecm sh ...

Purpose of readiness tests
The on-board diagnostic (obd ii) system is designed to monitor the performance of emission related components, and indicate any detected abnormalities with dtc (diagnostic trouble codes). Since various components need to be monitored during different driving conditions, the obd ii syste ...
