ON-BOARD DIAGNOSYS SYSTEM PID DATA/MONITOR FUNCTION OPERATION [ADVANCED KEYLESS SYSTEM]

id0914b51056b1

## On-board Diagnostic Function

### Malfunction detection function

  • Detects overall malfunctions in the keyless entry system-related parts.

### Display function

  • If any malfunction is detected, the keyless warning light (red) in the instrument cluster illuminates to inform the driver of a system malfunction.

### Memory function

  • Stores malfunctions in the keyless entry system-related parts detected by the malfunction detection function, and the stored malfunction contents are not cleared even if the ignition switch is turned to the LOCK position.

## PID/data monitor function

• The PID/data monitor function is used for optionally selecting input/output signal monitor items preset in the keyless control module and reading them out in real-time.
• Use the WDS or equivalent to read the PID/data monitor.
