Smart Key Diagnosis

Repair Procedures

Inspection

Self-Diagnosis Using Scan Tool. The scan tool can quickly diagnose defects in the SMART KEY system. The diagnostic tool can forcibly control actuators, monitor input/output values, and perform self-diagnosis. The following three functions are important in the SMART KEY system.

1. 1
   SMART KEY Device Input Problem.
2. 2
   SMART KEY Unit Problem.
3. 3
   SMART KEY Device Output Problem.
4. 4
   SMART KEY Unit Input Problem: Switch Diagnosis
5. 5
   SMART KEY Unit Problem: Communication Diagnosis
6. 6
   SMART KEY Unit Output Problem: Antenna and Switch Diagnosis
7. 7
   In the body electrical system, malfunctions can be quickly diagnosed using the vehicle diagnostic system (Diagnostic tool). The diagnostic system (diagnostic tool) provides the following information.

   1. DTC Search: Check malfunction and diagnostic trouble code (DTC)
   2. Data Analysis: Check the input/output data status of the system
   3. Actuation Test: Check the system operating status
   4. S/W Management: Control other functions, including system parameter setting and zero point adjustment
