ON-BOARD DIAGNOSYS SYSTEM OUTLINE (IMMOBILIZER SYSTEM)
E5U091467000N07
• The immobilizer system is provided with a malfunction diagnosis function.
• Malfunction diagnosis of the immobilizer system occurs automatically when the start knob is turned from the
LOCK (ACC) to the ON (START) position.
• If the results of the malfunction diagnosis show a malfunction in the immobilizer system, the security light
indicates a DTC. At the same time, DTCs are stored in the PCM and keyless control module. The stored DTCs
can be verified using the WDS or equivalent.
Caution
• Always use the WDS or equivalent to verify DTCs even if the security light indicates a DTC. If the
security light itself has a malfunction, it is possible that a DTC may not be indicated properly.
There are certain DTCs which can only be verified using the WDS or equivalent, not the security
light.
Note
• If two or more malfunctions are detected as a result of malfunction diagnosis, only the DTC with the lowest
number of those detected will be indicated by the security light. The PCM and keyless control module
store multiple DTCs at the same time.
• If two or more immobilizer system DTCs are verified, first repair the part of the DTC indicated by the
security light. After completely repairing one location, turn the ignition switch from the LOCK to the ON
position and perform immobilizer system malfunction diagnosis.
