Verifying DTCs using security light

Note

•  If multiple DTCs are detected, only those having the lowest numbers of those detected will be indicated by the security light.

•  A DTC is displayed ten times by switching the ignition ON once.

1.  Switch the ignition ON.

2.  Wait for approx. 1 min until the security light displays a DTC.

Note

•  When the ignition is switched ON with the following DTC detected, a DTC is displayed after the security light is flashed or illuminated for approx. 1 min.

―  If a DTC in the tens is detected, the security light flashes for approx. 1 min.

―  If a DTC in the twenties is detected, the security light illuminates for approx. 1 min.

•  If the security light turns off after approx. 3 s, verify the DTC using the M-MDS because the immobilizer system is normal or there is a DTC which cannot be verified by the security light.

3.  Read DTCs by the number of times the security light flashes as shown in the figure.

Example: DTC 12
