- If a malfunction is detected, the DTC pattern begins flashing after the security light flashes or illuminates for approx. 1 min according to the DTC. However, because there are DTCs which cannot be confirmed using the security light, verify the DTCs that were detected using the M-MDS prior to beginning the servicing.

- DTC 16 or below: Flashes for approx. 1 min and the DTC flash pattern repeats 10 times.
- DTC 21 or higher: illuminates for approx. 1 min and the DTC flash pattern repeats 10 times.
- If more than one DTC is detected, only the DTC with the lowest number is displayed.

- If there is no malfunction, the security light illuminates for approx. 3 s, and then turns off.

NOTE:
- The service code flashing pattern repeats 10 times.
- If more than one DTC is detected, only the DTC with the lowest number is displayed.

3. If there is a malfunction, verify the DTCs using the M-MDS. When several DTCs are detected, repair the malfunctioning location based on the DTC displayed by the security light.
NOTE:
- Because of the possibility that one malfunction cause could result in several DTCs being detected, erase the DTCs after the repair is completed, and then re-inspect the DTCs.
