Diagnostic Information and Procedures
Self-Diagnosis Function
S6JB0AA504002
The keyless start control module has self-diagnosis function to monitor the system components and circuits while the
keyless start system is at work. When the keyless start control module detects an abnormality in the system, it saves
the area where such abnormality has occurred as a DTC in its memory. The DTC stored in memory of the keyless start
control module is indicated by the key indicator light in the combination meter flashing in a specific pattern. For DTC
indication, refer to “DTC Check” and for the clearing procedure, to “DTC Clearance”.
Keyless Start System Diagnosis Introduction
S6JB0AA504003
To ensure that the trouble diagnosis is done accurately and smoothly, observe “Precautions in Diagnosing Troubles”
and follow “Keyless Start System Check”.
